How Do I Know If Water Spots Need Polishing?

Common Water Spot Causes

Sprinklers

Sprinkler water often contains minerals that can dry on the paint and leave bonded deposits behind.

Dried Wash Soap

Car wash soap can leave residue when it dries on the surface before being fully rinsed away.

Rinse Water

Tap, well or hard rinse water can leave mineral spots if it is allowed to dry on the vehicle.

Contaminated Rain

Rainwater can pick up airborne pollution and leave corrosive residue as droplets dry on the paint.

No one wants to obsessively wipe down their car every time water spots appear. But at the same time, you never want to let them sit for too long, or they’ll etch into the paint and require polishing to remove. So how long do you really have before it’s too late?
