removing hard water build up?

[93mr2red]

How do you remove hard water build up? It seems to appear underneath the windows where it traps the water.



Is this what spot sanding pens are for? I do not want to scratch the paint off.

Maybe a 50/50 mix of Iso/Water?

distilled white vinegar

With the vinegar, do you dillute it, or use it full strength?

The vinegar would have to soak on the calcium buildup for awhile to remove it. I know vinegar sometimes removes color, would it not fade my paint?



Have you tried this?

~One manâ€â„¢s opinion / observations~



Using diluted / undiluted distilled white vinegar should not noticeably fade the paint colour.

Try soaking a towel, wring it out so the vinegar doesnâ€â„¢t run and place it on the water spots





Have you tried this?

This is the 'usual' remedy to remove surface water spots. Yes I've tried it.



~Hope this helps~
