Lime Scale Removal
My son just bought a 2002 RSX Type-S with a very low 20K on the odometer. The car was stored for many years in an underground parking garage. Over this period, the concrete ceiling above the car leached out what looks like lime deposits onto the paint surface at a few locations like the rear bumper, and the hatchback door. While the scale can be worked off with a fingernail, it is stubborn and I fear all that scratching will damage the lacquer. I've tried my claybar and the chemical neutralizer CLR, to no avail.
Has anyone experienced this problem?
If yes, what solution could effectively dissolve this residue?
Thanks!

Concrete Spots:
Calcified water spots on paint and glass, water and concrete spots are pretty much the same chemically - calcium carbonate, with the concrete being cross-linked with water
Methodology
•Apply 1:1 ratio water with distilled White Vinegar solution, and using a spray bottle, spray that mixture on the spots and let them "soak." Then rinse with water and repeat as necessary.
•If the ambient temperature water/vinegar mix does not work, warm (100-120 degrees) 100% distilled White Vinegar, saturate a clean kitchen sponge with pure vinegar and hold the sponge over the concrete spots for a few minutes.
•If the above do not remove them try equal parts distilled water, isopropyl alcohol and distilled white vinegar. The acid in the vinegar will help etch and dissolve the concrete.
•Rinse the area thoroughly with water after the vinegar and then reapply wax or sealant to that area.
To remove concrete that has set use the A B C Decontamination / Neutralization system (http:// www.autoint.com) a safe alkaline wash and neutralizing system the ABC wash apparently loosens the bond with the clear coat, after using the wash simply lift off any concrete with a plastic razor, for smaller specks use detailers clay, any subsequent etching will require an abrasive to level the paint surface, and then reapply wax or sealant to that area.
