spots on paint

my car was parked in a N.Y.C. garage for about a week and leaks from the cement ceiling have left unsightly globs on the finish.I have tried cleaners,tar/sap removers even goof-off,nothing works to remove the spots.Someone thinks it could be lime drips.Any feedback on removal would be greatly appreciated.

Have you tried detailing clay such as "Clay Magic", the stuff by Mother's, or of course the Meguiar's clay? How about Meguiar's #7?

Give the above recommendations a try then let me know how it works. If no luck, then we'll take it from there.

Hope this helps...Lee

s9896:

If the leak actually came from the concrete ceiling as water drips, more than likely it could be "lime" or calcium carbonate, a water soluable mixture emitted by concrete.

Try to use a simple lemon - one you buy in a grocery store. Citrus acid will "dissolve" calcium carbonate, and will not damage your paint. It might remove the wax that might be on the paint, but not the paint iteself.

Try this first, as it is a cheap fix. If this does not do it, then it is not calcium carbonate, and you may have to spring for the clay......Andras

thankyou for both your suggestions but neither seem to work.I tried the lemon @the mequirs products and no results .The residue the drops left looks almost as if you could peel it off .It has a "crusty" coating to it.I have tried with my fingernail but it does not budge. Any more ideas would be appreciated.

You could also try "Goop" hand cleaner. (one of the few hand degreasers that has no abrasives) You might also try a bit of solvent type cleaner (Windex, 409, etc) on the finish but rinse, #7, and rewax immedately after use. Of course a few applications of Meguiar's #9 might be tried. If they work just a little bit but not much you will need a more aggressive rubbing compound. At that point, I'd suggest you call the Meguiar's help line for a case specific recommendation. The last resort would be wet-sanding but that is really really a last-ditch option. When you finally figure out what it takes to remove the spots let us know. Good luck and let me know how the above works for you.

Hope this helps...Lee
