Help Hard Water Spot Removal........ How to...... What to use?

[krzcuevas]

Good day everyone.  I just want some help and need your expert advice regarding my problem.
My newly bought car has no garage for 1 month, in short it's expose in rain and shine that's why it acquired hard water spots.  I already used GLASS SCRUB of Glass Science which promise to scrub smoothly the glass stains.  But after 5 tries its no use.  The question now is, it is really good to use rubbing compound with kerosene, or purely rubbing compound?  A friend of mine says it's bad for the glass, is it really true that it makes the glass brittle?  Any advice would be of great help and thanks in advance.....

to detail the glass of your vehicle and remove water spots, there are generally two types of chemicals you can choose from - paste/compound type (e.g. one grand, glass & chrome etc.) and the acid-based ones (elevo liquid, splash water spot remover etc.). if you use the latter, be sure no to get them on plastic parts or rubber trims. best if you seal these off first before doing anything. these two types of chemicals work in different ways but can achieve the same results. they can also be used one after the other. hope this helps!
