3 Things you are Doing Wrong | Car Wash
1. Using the wrong soap
You need to wash your car with soap that’s gonna suds up a lot, because those suds help move dirt away from your paint to prevent scratches. You also don’t want a soap that’s too alkaline for various reasons. That Dawn Brand Soap you’ve got sitting by the kitchen sink? It’s practically guaranteed to strip off any wax you’ve got on your car, and that’s a big NO, NO.
2. Washing in the sunlight on a hot day
The water-and-soap combo is a lubricant of sorts that helps the mitt glide across the paint without scratching it, but also, as the water dries, the minerals within it wind up etching onto the paint. You know how hard it is to get rid of water spots in your shower? It’s infinitely more annoying having those on your car, and you can’t scrub to remove them.
3. Using a regular towel
Normal cotton towels are neither very absorbent nor terribly soft. What’s worse: they’re moderately abrasive, so if you’re not drying your car with all the caution of a neurosurgeon, you’re inviting trouble.
