Windscreen Polishing

**zey** · 09-11-2004, 11:09 AM

Hi all, I have some very minor water mark on the front windscreen. Is it OK if I use PC with MG W-8006 Polishing Pad to apply #83 DACP on it for water mark removal? Will it mar the glass? Thanks!

I have not tried DACP but Autoglyms glass polish works well with a PC

Lowejackson, I have AG Glass Polish. But I`m wondering how does AG GP could do the cutting work if water spots had etched into the glass if it`s non-abrasive. Please enlighten, thanks.

I am not sure about this but I believe the polish does have some abrasives mixed in with the chemical cleaners.

The AG have never failed to remove water spots on my glass.

Can water etch glass :nixweiss

If AG GP can remove water spots done by British hard water, then I think it shouldn`t be a problem for me. Thanks for your help. I will try to use AG GP using W-8006 tomorrow. :up

Good luck. I would firstly clean the glass with vinegar before using the PC. This way your polishing clean glass and reducing the possibility of dirt causing any damage.

Thanks. I will clean the windscreen thoroughly first before polishing to prevent from scratches being instilled by the dirt.

Mr. Chemist, can water etch glass ie water spots

i`m pretty sure water spots will etch glass if left to bake on too long, this is what happened to my fathers car, even my fav autoglym glass polish didn`t get them off with some effort...

I`ve some luck removing the water marks using DACP with PC running at around 5000opm with MG Polishing Pad. AG GP doesn`t work at all in removing etched glass. I guess it`s designed to remove dirt and stains only.

water itself will not etch glass, it`s the chemicals in the water. Actually more like "leave water-spots".

Try some white vinegar on a cloth before wasting more of your valuable detailing products. White vinegar always does the trick for me, along with a good claying.

Water, no. Solubles in water, like industrial pollution and acid rain, yes.

Strange, it has never failed for me, maybe the water in Cumbria is purer than elsewhere :nixweiss
