The clear plastic cover over the dashboard gauges needs to be cleaned from time to time just like the rest of the car. You should take care when cleaning the plastic area, however, so that you do not scratch it. All plastics, even hard plastics, can be damaged easily by certain cleaning supplies.

Step 1

Wipe off the majority of the dust with a damp paper towel.

Step 2

Mix a mild soap and water solution with a dish detergent. Dish detergent soft and contains no abrasives. Do not mix this up with automatic dish washer detergent, which contains bleach and is a harsh chemical.

Step 3

Dip a soft cloth in the soap solution and wring it out.

Step 4

Wipe down the dash gauge covers with the rag. You can use this on the rest of the dash as well if you like.

Step 5

Dip the soft cloth in a bowl of plain water, wring it out and re-wipe the area to remove the soap.

Step 6

Wipe plastic gauge covers with a dry rag while they are still damp. Apply a little pressure to remove smudges.
