Hard Water Spots on Class A Windshield

[tazsport]

Does anybody have any magic formula or product that removes accumulated hard water spots on a the outside of a windshield ?

The spots will not come off with Windex, Magic Glass, etc..

The spots have been there to some degree since we purchased the motorhome new from a dealer earlier this year.

Have you tried vinegar? That's the old-timey limey remover.

[tazsport]

Do you have any suggestions on the ratio of water to vinegar, eg. 2 parts water to 1 part vinegar ? or straight vinegar ?

What harm could vinegar do to paint, if any ?

In a clean spray bottle (not a bottle that has contained other chemicals) pour 1 part white vinegar to 3 or 4 parts plain cool tap water. Give the bottle a good shake. This stuff is amazing on glass, mirrors, and all other surfaces in the home or RV. The smell dissipates quickly.

If you want to add extra cleaning power, add a squirt of natural liquid soap.

I have the same problem on our side windows. Tried vinigar straight and dilluted, trouble is it dries to fast.
I've heard folks mention Bon Ami, #00 steel wool (both are mild abrasives), Gel gloss (or the No Streak glass polish), A-MAZ, and CLR. You have to be careful, some are not safe on paints.

Bon Ami will do it every time. It will not scratch the glass and you can just rinse it off.
Try it if the white vinegar doesn't work. Use the white vinegar on the inside of your windows, you won't believe the difference.

CLR works too. I've used it full strength on a sponge and immediately wash it off anything else.

Bon Ami was and may still be sold at GM parts departments under the GM name.

It does work well.

Do no use Ajax, Comet, etc. Only Bon Ami.

Hi Tazsport

Here are two products that will be helpful-- I've used both with good sucess-

What works quite well is using a razor blade. Spray the surface with window cleaner or vinegar and while it is wet lightly pass the razor blade on the complete surface. As long as you keep the blade flat, it will not scratch the glass.

I learned this long ago when they would put tint on windows to clean it back to the original surface. I have used it since and you will be amazed how much accumulation that builds up on the glass. In fact, I did it to my coach last summer before the vacation trip. It works for me.............

They use steel wool on windshields quite often. Just make sure the window is free from grit, there is no rust present in the steel wool pad, and it's a superfine or #0000 grade. #00 is too course. You don't have to wet it, clean the window and polish with the steel wool till the spots come out.
Same with razor blades, safe on glass but make sure there is no grit to get caught under the blade and possibly scratch.

Mineral spirits are also good for use on glass for cleaning per Anderson windows. I have not tried using them myself yet.

Do not use steel wool or blades if you have a film or tint on windows.
