How to Deal with Whitening of Automotive Plastic Parts?
2 Answers
Here is an introduction to whitening of automotive plastics: 1. First, assess the whitening condition. If it is a light white mark, use a damp towel to wipe it, and there will be no trace after drying; if there are still marks after drying, it indicates scratches. 2. Spray dashboard wax evenly around the scratches, wait a few minutes, and then repeatedly wipe the dashboard wax with a clean, damp towel. The hard plastic treated with dashboard wax will no longer whiten. 3. If whitening persists after treatment, you can try using black shoe polish. First, clean the whitened plastic part, then apply the shoe polish to the plastic part. Wipe it back and forth with a clean cloth. It is best to have a heat gun, set the temperature to about 200 degrees Celsius, and apply and wipe while heating. After even wiping, it is advisable to apply a layer of dashboard wax if possible, as this will prolong the effect.
I've seen plastic car parts turning white many times, often due to oxidation from prolonged sun exposure. The solution isn't difficult: first, gently wipe the whitened area with mild detergent and water to remove surface dirt, then apply a car-specific plastic restorer paste for a few minutes before wiping it off - this can restore some color. For long-term protection, buy a UV protection spray and apply it weekly to prevent re-whitening. When parking, try to find a shaded spot or use a sunshade to avoid direct sunlight. I keep a maintenance kit in my garage and found that regular care significantly reduces whitening issues, which both protects the car and saves money.
