Beach-town tint care guide: how sand, salt spray, and sunscreen residue damage window film, and the cleaning routine that keeps it looking new.
**Short answer:** rinse before you wipe, use an ammonia-free cleaner and two microfiber towels, and never dry-wipe sandy glass. That's 95% of beach-town tint care.
Dry-wiping sandy glass drags grit across the film's hardcoat. That's the fine scratch haze you see on beach cars. Always rinse or spray first.
Leaves a mineral haze that fogs the view and makes people scrub harder — which causes the scratching above. Wash weekly if you park near the water.
Oils transfer from hands and arms to the inside of the door glass and smear badly. Ammonia-free interior glass cleaner removes it; ammonia will eventually break down film adhesive and dyes.
1. Rinse or mist the glass — never start dry 2. Ammonia-free glass cleaner sprayed on the towel, not the glass 3. Wipe with microfiber towel #1 (horizontal outside, vertical inside — makes streak sources obvious) 4. Buff dry with microfiber towel #2 5. Never use paper towels, razor blades, or scrubby sponges
