- Projector: Deep clean before every show (if you’re running shows close together at least clean the gate and trap and wipe down the rollers). Deep cleaning is a great time to check for any stalled rollers or broken, worn sprocket teeth or burrs. Between reels wipe down the gate and trap and rollers. Pull the aperture plate out and clean it so dirt doesn’t accumulate there. A clean toothbrush can be used to clean the sprockets,gently press the toothbrush to the sprockets as the motor is running. Use the canned air last as it tends to blow the dirt deep into the projector.
- Lenses: Clean monthly. Use only optics grade lens cleaner and lens wipes (no Kimwipes!). Apply liquid to lens wipe, never directly to lens. Wipe very gently, using a circular motion. Use this time to check for any cracked or fogged lenses. Never clean a hot lens.
- Port glass: clean your port glass on a regular basis! Use lens cleaner is a spray bottle (best) or 99.9% isopropyl alcohol. Do not use windex or 50% vinegar, 50% water mixtures unless you are certain they won't damage whatever type of optical glass you have in your ports. Damage to the coating of the optical glass can happen if you're using the incorrect cleaner or rubbing to vigorously. Lens cleaner is your safest option if you are unsure. Let the liquid do the work. Spray liberally and clean gently with a microfiber cloth or paper towels. If you can see the action of the film reflected on the port glass IT’S TIME TO CLEAN IT.
- General booth cleaning: Have a shop vacuum, keep surfaces and floors free of dust and debris.
Cleaning Film Prints
- Projectionists handling archival prints should NOT be cleaning the prints. Poorly maintained or improperly used cleaning equipment and supplies can do a tremendous amount of damage, so it's best not to do it. Cleaning equipment is really designed to clean prints that are run for an extended length of time at a venue, and chances are you're only running that archival print a few times.
- Solvents etc.
- Ultrasonic cleaners
- PTR Rollers: Again, Only use them if they are very well maintained and clean and you know what you are doing. Dirty PTR rollers can do more damage than good. PTR rollers are very good at keeping a perfectly clean print dust free, but the benefits of running a very dirty print through PTR rollers are negligible at best.
