sprinkler or hard water on my paint..

and you are who?

clay will take contaminants off including water spots. if its etched into the paint then polish will work if it only penetrated the clear.

He is right, it won't....

Use a half and half mixture of vinegar and water, then follow it with your choice of wax.

then that stain was sitting too long. ive removed water stains from our office doing these sprinkler tests in the spring and evacuating the water in the pipes before winter and each time the stains came off off my car. these are stains that would not come off with a regular car wash.

the vinegar and water trick does work, but you need to use at towel, soak it with vinegar and keep spraying solution over it (not to evaporate) and it's takes a long time for the solution to dissolve the stain. if you want to sit there and wait, good for you.

ive been detailing cars for a while and if the clay does not work, i take my mild polishes and random orbital and remove it that way. just faster and more convenient.
