Waterspots from hell...

[shankscomp]

OK, I don't get what the hell I got on the truck, but trying to get rid of these things are a challenge.

When I wash my truck, these spots reappear in the location. Usually it takes a day or two before they show back up again. I have attached pictures, hopefully you can see the white circles... They are textured, and if you scratch them with your fingernail, they turn to a powder. I just want to know what I need to do to get rid of them.

Thanks
Tim

Looks like hard water dried there and thats whats left. Wash your car with soft water and thoroughly dry. They will disappear.

Hard water will do that.. I had the same issues with my last black truck at my older house before I moved.

Back when I was researching, I think most people used inline water filtration systems to help with this. But it's been awhile..

Try mixing vinegar and water 50/50. Spray on with spray bottle from home depot. Wipe off with cloth.
