Illustration for Scratched or Hazy Car Screen

Owners raise this in detailing forums. One said a detailer left long wipe scratches across the infotainment screen and then stopped replying.

How carmakers say to clean a screen

Manuals differ, so check yours. One carmaker’s support page says to use a clean, soft cloth like one for cleaning glasses, and to put a small amount of alcohol on the cloth if fingerprints remain. It warns not to pour or spray alcohol onto the display, and not to use detergent or any solvent. Another carmaker’s owner’s manual is stricter. It says to turn the ignition off and wipe with a dry soft cloth. It says never to use a rough cloth, alcohol, benzene, thinner, any solvent, or tissues with chemical cleaners, because they would scratch or deteriorate the panel. It also says not to splash any liquid, such as water or car fragrance, on the display. For an extreme stain, it allows a small amount of neutral detergent on a soft cloth, without soaking the screen.

Going by those pages, a glass cleaner or an all-purpose interior spray wiped across the screen can be the wrong product, depending on the car. If a detailer is cleaning your interior, tell them which screens to skip or how your manual says to clean them.

What can be fixed, and what it costs

Damage Realistic fix Cost
Smudges, streaks, a film after cleaning Clean again the way your manual says A soft cloth
Hazy patch that won’t wipe off Clean per the manual first; if it stays, have the dealer look Inspection, then a quote
Light scratches Live with them; a protector stops new ones $44.99 for an anti-glare glass protector (Spigen, Toyota models)
Deep scratches or a worn-off coating Replace the display unit $4,813.24 list for an older Prius V unit; $6,066.92 for a Corolla 8-inch unit; $10,180.17 for a Highlander unit (one Toyota dealer’s parts site), before labor

The middle column is our reading of the carmaker pages and listings in the Sources. How we research: methodology.

The dealer listings call each part a radio, display unit or receiver assembly, so the screen comes with the head unit. The same dealer’s site showed sale prices below list on the day we checked: $3,212 for the older hybrid’s unit and $4,048.61 for the 8-inch unit. The top-priced listing is for a 12.3-inch touchscreen and notes that it includes the navigation display. Get a quote with your VIN; the part varies by trim and audio system.

Prevention is cheap

A glass screen protector costs a tiny fraction of a display unit. Our guide to interior film on screens and piano-black trim compares a DIY protector with shop-installed film. The protector in the table is a matte, anti-glare glass piece sold by screen size, from 12.3 to 14 inches on the listing we checked, so buy the version listed for your exact model and year. Fit it to a clean screen, after cleaning the way your manual says.

If a detailer caused it

Raise it soon, with photos taken at an angle in good light, and ask what cloth and product touched the screen. Keep it in writing, and get a dealer parts quote so the conversation has a real number. If the shop goes quiet, our guide to getting a bad detail fixed walks through the next steps, and what a detail can’t fix covers the line between cleaning and repair.
