How to Remove Air Conditioner Water Stains from Car Paint?
2 Answers
When air conditioner water drips onto walls, the lime from the walls can combine with the moisture to leave white marks on the car paint. These can be cleaned using an acidic solution. First, soak a paper towel in hot water, then apply a little vinegar to the surface of the towel and place it over the stained area. Wait for ten minutes before rinsing with clean water. Alternatively, you can purchase an air conditioner water stain remover online and use a specialized towel to wipe away the stains. Air conditioner water stains are relatively easy to remove. Remember not to use hard objects to scrape off the stains, as this can easily damage the car paint.
I've got so much experience with this! Last time I washed my car, I found yellow stains from air conditioner drips all over the hood. The most cost-effective solution I found was using white vinegar from the kitchen. Remember to rinse off loose dust with water first, then mix white vinegar with warm water 1:1, soak a towel, and cover the stains for 10 minutes. Wait for the calcium deposits to soften before gently wiping in circles. If the stains are too stubborn, those nano-cleaning clays from car detailing shops work wonders. Use them with lubricant spray and push like kneading playdough—even water scale in door gaps and corners can be removed. Finally, you must apply wax or ceramic coating because the heavy metals in AC water seriously damage the clear coat! Never use steel wool for DIY cleaning—scratches on the glaze will cost way more to repair.
