Removing water "spots"

[Puffs Daddy]

Actually, the problem is more than the usual "spots." Several months ago while I was out of town my wife had our driveway and patio "pressure washed." The folks who did it dragged their hoses through the garage and (apparently) sprayed my valk from a leak in their hose. Once dried, the residue left a large number of spot and drip marks on the paint, chrome, windshield, etc. The marks are thick enough in places to feel them with a finger.

I've tried a variety of non-abrasive approaches to cleaning them off. And after multiple washings, I've managed to remove most of them. (Though some I thought were gone appear to magically reappear from time to time.)

I've concluded that they are mineral deposits that are particularly stubborn to remove. Before I take the next step of applying a polishing compound or some sort of solvent to remove them, has anyone encountered this problem? And, if so, how did you correct it?

Have you tried Meguiars paint cleaner? I've used that with success on heavy water spots.
Or a clay bar perhaps?

For removing water spots of the type you've mentioned, I use a solution of 50% vinegar & water in a spray bottle.  Apply, let it work for a while, wipe off, rinse and repeat if necessary.  Vinegar, being a very mild acid, will dissolve the mineral deposits.  If really stubborn, wet a rag with just vinegar and wet the spots & let work for a minute or so, wipe off, repeat as necessary then rinse.  Will not harm paint or chrome.
