Dust, traffic film, and rain spots mute LED and vinyl surfaces. After dark, that buildup turns into haze and glare—letters bloom, contrast drops, and your message underperforms. The fix is simple: regular, LED - safe cleaning done the right way.

What Cleaning Does (and why it matters)

• Removes the film that kills brightness and contrast.
• Cuts the particles that create glare halos around white areas.
• Restores deep blacks and crisp edges for better night readability.

Safety & Prep

• Power off the screen before cleaning.
• Work in dry, calm weather with cool panels.
• No strong solvents, no abrasives, no pressure washing (risks damage and water ingress).

Tools & Cleaning Agents (gentle, LED/vinyl-safe)

• Lightly damp microfiber cloths / soft brush
• Distilled water or a mild, LED/vinyl-compatible cleaner
• Dry, lint-free cloths for finish

Step-by-Step: Cleaning for Visibility

1. Dry dust removal: soft brush/air blower to lift grit and loose dust.
2. Main wipe: apply liquid to the cloth (not the screen); straight, overlapping passes with lightly damp microfiber.
3. Edges & seams: detail bezels and shrouds—dirt here migrates back onto the image area.
4. Dry down: finish with a dry microfiber until no moisture remains—no drops, no streaks.

Even a thin film can eat a noticeable share of perceived luminance and create a “milky” glow at night.

Glare Control via Cleaning

• A clean surface delivers even light without sparkly points.
• Removing road salts/mineral spots reduces unwanted reflections.
• Clean, dry borders around the active area minimize stray light.

How Often to Clean

• Baseline: monthly.
• Dusty/polluted routes or winter de-icers: every two weeks.
• After heavy rain or sandstorms: do an extra wipe.

Quick Fixes

• Streaks after cleaning: re-wipe with distilled water, finish dry.
• Rain/road salt marks: spot with mild cleaner, then dry thoroughly.
• Overall “fog” look: schedule a full-surface clean—spot fixes won’t restore uniformity.

FAQ (short)

Can we pressure wash? No—risks water ingress and pixel/module damage.
What’s safe to use? Distilled water or a mild LED/vinyl-compatible cleaner on a lightly damp microfiber cloth.
Do we need to dry afterward? Yes—any moisture at seams/edges leads to streaks and reduced night clarity.
Do you do inspections or calibration? No. Cleanline performs cleaning only for billboards.
