Ammo NYC demonstrates in a video how to remove car door handle scratches in less than 10 minutes. The problem with the car handles is to reach the behind area to clean, polish, and revive its aspect.
On a tip from the start: lock the car, because the process requires repetitive open & close actions. First of all, as usual, you must wash thoroughly the problematic area by constantly opening and closing the door. The next step is to dry it also with the most possible meticulosity to get all the trapped water.
It’s quite tricky to get the cleaning tools behind the door handles – you’ll need to do it manually to avoid damaging the paint. Hand polishing is the best for modern cars where the plastic is easily exposed to damage in a mechanical procedure.
What seems simple, has some great inside tricks to teach you. Watch and learn!
