1. Daily Cleaning: Be gentle and avoid irritation.
Basic Cleaning Tools:
Preferably use a soft, slightly damp cloth (such as a glasses cloth or microfiber cloth). Avoid using rough cloths (such as steel wool or scouring pads) to prevent scratching the surface texture or gloss.
For cleaning, choose a neutral detergent (such as baby shower gel or neutral dishwashing liquid, diluted before use) or simply use water. Avoid using acidic (such as white vinegar or toilet cleaner), alkaline (such as baking soda or soapy water), or detergents containing alcohol or solvents (such as gasoline or nail polish remover). These can corrode the celluloid surface, causing discoloration and cracking. Cleaning Instructions:
Gently dust the surface with a dry cloth (avoid static electricity caused by dry rubbing, which attracts more dust).
Damp a damp cloth in a small amount of neutral detergent, wring it out until partially dry, and then gently wipe the stain. (For localized stains, only wipe the affected area; there’s no need to soak the entire surface.)
Immediately blot any remaining moisture with another clean, dry cloth, ensuring the surface is completely dry. (To prevent prolonged moisture penetration and warping of the film, this is essential.)
II. Special Stains: Targeted Treatment, Avoid Brutal Force
Grease Stains/Fingerprints: Use a slightly damp cloth dipped in diluted neutral detergent and gently rub in circular motions. Dry immediately. Do not use alcohol or degreasers.
Paint/Handwriting: For water-soluble paints (such as watercolor), simply wipe with clean water. For stubborn stains like oil-based markers, gently rub with an eraser (soft art eraser) before cleaning with a damp cloth. Do not use stain removers or banana oil, as they will dissolve the celluloid surface. Glue residue: Dip a cotton swab in a small amount of warm water and hold it on the glue for 10-15 seconds to soften the glue. Then use an eraser or soft cloth to gently peel it off. Do not scrape it with a blade (it may damage the surface).
