Cleaning, Storing, and Repairing Your Classic Camera

Unlike the digital camera market, which is saturated with brand new products and the support network needed to fix them, film cameras can be rare and precious and expensive to fix. That’s why it’s important for all film photographers, from the most casual point-and-shoot lover to the dedicated hoarder of rare Leicas, to know how to look after and maintain their gear.

Here are a few basic tips to help you understand how to store, clean, and fix (if need be) your beautiful, old camera.

How to Clean a Camera

Most of my gear has been obtained from secondhand shops, boot fairs and eBay. While these places are often the cheapest places to buy film camera bodies and lenses, it’s rare to find gear that has been stored and maintained correctly. The older the camera the greater the chance that it’s been mishandled or improperly stored at some point in its life. It’s best practice, therefore, to give the camera or lens a thorough inspection and cleaning immediately when it arrives.

Having the proper gear to do the job is essential. Cameras have lots of nooks and grannies, and unmentionable gunk often accumulates in these tiny places. Around the dials on the top of the body, surrounding the viewfinder, and on the leatherette – think of all those hands that have gripped, sweated, and smeared on your new toy. Eurgh! Luckily, decades of dirt can be easily cleaned away with nothing more than soapy water, lens cleaner, a pack of cotton buds (Q-tips), and two or three microfibre cloths (both damp and dry).

Start by dipping a microfiber cloth in a little bit of soapy water (simple soap is fine), and use it to wipe off any visible grime you can see on the camera body. If your camera has a built-in lens, leave it until last (think of it as doing the windows of your car last – you don’t want to have to clean the same area twice). If you’re cleaning an SLR, remove the lens and be careful not to get any water inside the body of the camera. It’s best to carefully clean the reflex mirror with a dry microfiber cloth. Don’t touch the focusing screen up top with anything, simply use an air blower to blow the dust away. Lastly, clean the external lens mount and then fit a body cap to keep things protected while we clean the rest of the body – we don’t want any liquids getting inside that mirror box.

If the mirror and focusing screen are very dirty, we can use a light amount of isopropyl alcohol on a soft Q-tip to clean these delicate components. Be sure to roll across the surface of the focusing screen, rather than drag, and use very little alcohol (just enough to clean the surface – otherwise capillary action will draw the alcohol onto the other side of the screen). If the camera has a removable focusing screen, this process is easier and less stressful. Once the screen and mirror are cleaned, use an air blower to dry the focusing screen and use a microfiber cloth to polish the mirror back to a shine.

For cleaning of the external body of the camera, you don’t want the cloth to be soaking wet, just damp. Patience, good lighting, and cleaning a small portion at a time are all keys to success. After the initial once-over, go in with the cotton buds, dipped in a bit of soapy water (you can also use isopropyl alcohol, everyone has a preference) to get into all the tiny nooks and crannies. A toothbrush is also helpful for reaching the hardest and finest areas (think the knurling of an ISO dial, where plenty of dirt can hide).

The inside of a camera can also suffer if not stored and cleaned properly – the main offender being the foam light seals that line the camera back door. These degrade over time, and can turn into a crumbly, sticky mess that can be a real pain to clean and replace. It’s worth looking at the light seals inside any camera you’re buying, if possible, to save yourself extra work further down the line.

If need be, old light seals can be removed with a scraper tool (something plastic is best, or a wooden cuticle stick with a wedge end), then the glue residue can be removed with alcohol on a cotton bud. SLR mirrors sometimes have a mirror bumper (a pad of foam lining the upper edge of the mirror box) to dampen mirror slap, and it’s worth checking to see if this is intact too.

New light seal kits can be bought online inexpensively – Nik & Trick sell replacement foam kits for a lot of the more common models and sellers on eBay supply these as well. They’re usually of the pre-cut, peel and stick variety, but the ease of replacement of light seals is dependent on your model of camera – some are easier than others!

[Editor’s Note – the photo below is horrific and this method of cleaning should not be tried at home, or anywhere.]

Don’t do this.

Once the body looks a bit cleaner, start on the exterior components of the lens. Clean the aperture and focus rings with a cotton bud or toothbrush dipped in soapy water and squeezed out – you don’t want any fluid to get inside the lens at all. Be careful around painted marking – soapy water shouldn’t harm anything, but rubbing alcohol can actually dull or completely strip paint from certain models.

Now we’re ready to clean the glass. Use a clean cotton bud dipped in lens cleaner fluid to gently clean the lens glass. Start in the center and swirl outward. Try to keep from getting any cleaner on the outermost edge of the glass, as it can sometimes spread to the outside edge of cemented elements and seep where it’s not supposed to go. This is an exercise in patience – go slowly, and be sure to get both the front and rear elements of the lens, as dust can accumulate everywhere.

If all this scrubbing sounds a bit much for you, or you simply don’t have time, it’s worth finding a local camera repair shop that offers CLA service (clean, lube and adjust). In the UK, my go-to is Miles Whitehead, and I’d recommend him to anyone having camera troubles!

Storing your Camera

Once your collection has expanded past a single body and one or two lenses, it’s worth looking into the best way to store your gear. Cameras and lenses need to be stored in a dry, cool environment (sorry, Floridians) to avoid damage to the seals, and to stop fungus growing inside lenses. Ever picked up an old camera and smelled a musty aroma? That’s mold, my friend, and you want to avoid it as much as you can.

Ideally, cameras should be stored in a climate-controlled room with low humidity, away from direct sunlight, and inside an enclosure that protects them from dust. For displayed collections, the best solution is a humidity control cabinet, which we’ve reviewed here. For user cameras, the most common (and easiest) solution is to store your gear in a relatively small, sealed container and to throw a few moisture absorbing silica packets inside. This should absorb much of the extra moisture in the contained space. Replace the packets as needed and the camera will last forever.

Most shooters probably already have the ideal storage solution already – your camera bag! A nice, padded bag or backpack is perfectly suited to hold multiple bodies and lenses, so why not use it? As long as your bag isn’t damp or dusty or dirty, put your gear in a bag and then into a closet in your living space. Just like you, cameras and lenses don’t want to live their lives in a basement or attic where temperatures and moisture levels are uncomfortable. If your everyday camera bag accumulates rainwater and dust, buy a bag specifically for storage and never take it our of the house.

Remember to store lenses with both lens caps on and sitting upright when not on the camera. This way the lens will be safe from dust and the lubricant in the focusing mechanisms will stay where it’s supposed to, rather than migrate onto the aperture blades. When lenses are stored attached to a camera, make sure the caps are on as well – sunlight passing through the lens can act like a magnifying glass and burn a hole into shutter curtains.

As for camera bodies, if you have body caps, use them! They’ll stop dust getting into the body itself. Remember to remove batteries from any camera bodies you’ll be storing for more than a few weeks to avoid battery leakage, corrosion of electrical contacts, or unwanted battery depletion.

For most cameras it’s best to store them with shutters uncocked. This reduces stress on tension springs, curtains, and gears inside the camera body which can lead to shutter speeds becoming inaccurate. Of course there are certain exceptions – check your individual camera manual for advice on whether or not to store cameras with shutters cocked or relaxed.

You should also consider proper storage of your film stocks. After all, there’s no point buying expensive rolls of Velvia and letting them get ruined in a hot car glove box. All film rolls will have an expiry date – this is the date before which a manufacturer recommends using the film to achieve optimal (and predictable) results. Know these dates and stack your film with the freshest rolls on the bottom.

Personally, I store everything that’s not dollar-store film (sorry, Agfa Vista 200) in the salad crisper drawer of my fridge. Refrigerated film lasts much longer than film stored at room temperature – just make sure you acclimatise it properly before loading it into your camera. Thirty minutes at room temperature should be fine.

If you have a huge stock of film you want to use for years to come, you may also want to freeze your film in a frost-free freezer – just be sure to thaw them before use. Bear in mind that many 120 roll films are stored in foil packages, which don’t keep humidity out. You may want to keep 120 rolls in a plastic container, to keep the moisture out (another use for those handy little silica packets).

Repairing Your Camera

Inevitably a camera will break, or we will find a deal on a gorgeous but malfunctioning camera that’s simply too good to pass up. In some cases it’s even advisable to buy a slightly damaged or broken camera in order to get a great deal (as long as it can be fixed).

The simplest repairs are cosmetic repairs or replacement of simple parts – leatherette replacement, swapping a broken nameplate for one that’s intact, battery cover replacements, things like that. These uncomplicated repairs are easy, and can even be therapeutic relaxation for those of us with busy lives. We spent a few months live-streaming simple repairs, which you can find on YouTube. The basic principals can carry you through easy jobs like cleaning oily aperture blades, replacing capacitors, etc.

You’ll also need decent tools. Buy a good set of precision screwdrivers, a precision knife kit, a silicon repair mat with parts holders, a fine set of tweezers, and (believe it or not) dental tools. In addition, get some rubber stoppers to remove circular objects (such as lens bezels) and a lens spanner tool.

With good tools, patience, and ample pauses to refocus and center the mind when things go awry, it’s easy for even the most ham-handed among us to repair and improve these old cameras. When repairs are too complicated it’s best to simply pass the job off to a professional. There are still plenty of excellent repair shops operating today, and many that specifically focus on individual brands or models.

With a little time and love, these small steps can ensure your beloved gear will last for many years to come.

Based in Bristol, transplanted from London, I have been taking photos since I could hold a camera (sometimes I still drop them, but the sturdy ones survive).

  • Sound advice, I wrote an article in AP magazine some 20 years ago on a similar subject where I had obtained an old non working camera with a defective meter from a boot fair. I had to open the camera casing to access the meter only to find a broken wire on the meter, resoldered and hey presto a working camera

    • Charlotte Davis June 12, 2019 at 5:17 am

      Boot fair cameras FTW! Soldering is a bit beyond my knowledge, unfortunately. When I dismantle cameras I tend to end up with the dreaded Leftover Screws…

  • A set of vacuum attachments are better than a blower for clearing the inside of a camera, as they actually remove the dust rather than just redistributing it as a blower tends to do. I use the soft tipped probes as sold by Green Clean but with a regular domestic vacuum cleaner rather than their gas aerosol venturi device. Not only is it a lot cheaper to run (and safer as you are not squirting inflammable propane/butane into the atmosphere around you) but the vacuum is considerably stronger as well. Be very careful not to touch the shutter. Particularly titanium blades are extremely thin and fragile.

    I often find that top mounted mode and power switches have dirty and corroded contacts, as they have been sitting under the users nose for years, getting moisture saturated air breathed on them. You have to be extremely careful with ribbon cables when removing a top cover and make sure you put them back with the same bends as original, after checking there are no wire breaks at the bends.

    Thank you so much for this write up. Personally, I have been wanting to dive into repairing some of my film cameras that I pick up on the cheap. Found the list of important tools (and their links) helpful.

  • Add toothpicks to your cleaning gear. They get into the tinniest crevices and won’t scratch.

  • I always use lens liquid cleaner made specifically for camera lenses. Never use Windex or regular glass cleaner liquids. They can damage lens coatings. I use lens cleaning paper. Roll one up, tear off and edge saturate and begin wiping lightly in a circular direction.Dry with a fresh paper. No need to rub hard. Just repeat all of that until lens looks clean.

  • Michael J. Ricciuti June 12, 2019 at 7:36 pm

    Nicely done. Another extremely useful tool: flexiclamps (google it). You can buy a nice assortment for short cash on ebay. They are very handy for work on most cameras, and are particularly useful for any work on Leica M/CL bodies. And yes, a dental tool is very useful.

  • Hairline scratches on the mirror bother me a lot. Never ever touch the reflex mirror if you can help it. It’s a thin layer of soft metal bonded to the glass. It scratches if you breathe on it wrong.

  • On storage, don’t neglect proper selenium meter storage. I have some selenium meters and cameras with selenium meters from the late 1950s/early 1960s that are still working and reasonably accurate. Although they make interesting displays, exposure to light activates and ultimately degrades the selenium. I store selenium meters in a bag or drawer to keep them away from light. On one displayed Retina with a still accurate meter I keep a piece of black craft paper over the cell. Just simply fold the paper to sit over the top of the camera and hang down far enough to cover the meter.

  • Great article! Most everyone knows about getting a good lens spanner and screwdrivers, but I am happy to see you promoting what is the single best tool for cleaning a camera….the toothbrush! 🙂 I buy 3-packs of the generic ones at the dollar store and throw them in my camera repair/cleaning box and use them all the time!

  • Pouring water into an SR-T 201, as in the photo in this article, is surely inadvisable. That said, of all the cameras I own, my SR-T could probably handle it and still work afterwards. It is indestructable! 🙂

    • There is a comment somewhere among this website’s 7,600 comments that told a great story about an SRT. The user’s camera fell into a river in a jungle. To clean the water away and to get back to taking photos, the photographer removed the bottom plate and poured Vodka throughout the internals. A few hours of evaporation later and the SRT reportedly worked like new (for another decade or so).

    • From a 201 owner, thank you. Yes, I’m late to this party .

  • One question prompted by your excellent advice: Several other online sources suggest that “consumer-grade” current-day films do not require refrigeration, just storage at room temperature. What say you?

    • Refrigerate it. It is just as sensitive to heat as ‘pro’ film. Take it from the experts – people who make the film. Reading the information from the box of my Fuji C200, the first thing it says is , in red and bold, PROTECT FROM HEAT AND XRAY. Same for my Fuji Superia XTRA 400.
      Storing at room temp is fine short term, as is with pro films.

      I think this myth started with someone on the internet claiming Kodak ProImage 100 is designed for hot climates where heat doesnt effect it. It is not. It is a version of Kodak 100/Gold that was marketed for the Far East, and slapping the name ProImage on it is just rebranding. But someone read that somewhere and then others read that posting and thus it became a thing.

    • It can’t hurt to refrigerate. Short term, it likely won’t matter if it’s refrigerated or not, but if you’re keeping the film for more than a week, why not throw it in the fridge?

  • For the lenses, it’s good if they see the sun once in awhile to keep the fungus away. Long term storage in the dark is not a great thing, a little UV light now and again keeps them protected. For an SLR the sun shouldn’t shine through and hit the shutter curtain, since the mirror is in the way.

  • Great info….I have a good camera tech but I try to do the basics, replacing light seals, cleaning etc….

  • I keep my small collection in transparent IKEA boxes with some silica gel for moisture control:
    Lenses stay with the caps off so they are exposed to light – another defense against fungus. Obviously stored away from direct sunlight.
    But of course, the best way to properly maintain a camera is to use it once in a while.

  • How about using moebius lubricants on aperture rings and stuff ? The shutter speed ring on my 35 Sp feels a little rough
    Thanks for the post.

  • Simple soap yes. Not washing up liquid though, that will corrode metal over time leaving holes in it. You can get metal cleaning soaps.

  • Many thanks for this, its taken me an age to find an article like this. I have a small collection and I want to keep it in the best health. I had a Canon 5dmk2 before I moved back to film and I didn’t use it for a few months, I wanted to sell it, next time I used it the shutter mechanism exploded and I had to get the shutter replaced(only 30,000 shots taken). Canon told me that I should fire off a couple of dozen every few weeks to stop the oil from thickening and as causing the shutter from jamming. Is this something I would see with a film camera including all the different types of shutters, many thanks again

    Great article. Now that I have a few collections of film cameras I need to start cleaning them and start using them. Your right I find it relaxing sitting at a cafe and just listening to music while you clean your cameras.. Will be heading to Starbucks today to clean my Nikon F4 I just got…

  • Hi,

    I’m not as brave as all of you! I have an eBay bought Konica S2 that’s supposed to work, but I’d like it cleaned and lubricated and repaired if necessary. Whom do you recommend in the USA?

  • Michael Steward April 5, 2023 at 5:13 pm

    I have 11 Kodak fold-up cameras vintage of 1900. I clean with 91% alcohol, Q-tips, a hypodermic needle to get the alcohol into the tight places If it oozes beyond the target area, it evaporates within seconds. (I dropped my cell ph into a full kitchen sink… I opened it up, poured 91% alcohol in to its “innards,” put it in the sun for a couple of hours and it was back in full operation.)
