I did consider doing a clay bar on the glass, that only works if the glass is brand new and not pitted though lol. Ok so what is a "glass towel" lol. Just been using microfibers.

:icon14: Completely untrue. Based on that statement, I'm not sure you understand how clay works. A clay bar actually pulls embedded contaminants out of the clear coat on your paint. Same with the pitting on your glass. If there is pitting in your window so deep the clay bar is not working, then it sounds like you have chips that need repairing.

A glass towel is a specific type of microfiber towel with low pile and much tighter woven fibers. They will do a much better job than a standard microfiber towel when it comes to glass. Even cheap glass towels from the local auto parts store I find work far better than the high quality Eagle Edgeless microfiber towels I buy from The Rag Company.

:iagree:

I used Klasse auto polish once, worked well...think any polish will work as long as it has a little grit in it

So many post and no mention of filtering the water. You need to add a filtration system , and wash your car during the evening after the car cools down. :)

:ugh2: several mentions of it already...... even the op mentioned it.

That's essentially what I am talking about with pits, im not talking waterspots, im talking a ton of tiny tiny pits in the glass from weathering over several years. If the clay goes over these and gets trapped, I bet it wouldn't be fun to try and remove.

I know exactly what a clay bar is for, its just something I read on a detailing website about using clay on glass, and it kinda makes sense if it is a real old beat up windscreen.

I will clay bar my windshield every now and then to get rid of the gunk that chemical cleaners don't want to remove. It seems to be easier on the glass than using an abrasive cleaner. YMMV

For minor pitting of the glass, you might try polishing with an appropriate abrasive and an electric buffer. The pits will still be there but less visible.
I've seen products that are supposed to fill in the pits but have no idea how well they work.

It won't get trapped if you're properly lubing (detail spray) while you clay. I put over 95K miles on my first windshield before having it replaced recently. Never once worried about the pitting in it.

Basically, get an inline water softener from lowes or home depot, with the necessary garden hose thread adapters (like the ones in the pics). If your water is too hard, you may have to get an additional de-ionizer filter too.

Well, that sure is reassuring!

Klasse does the job. I had a lot of water spots. I tried a few different polishes and water spot remover. Klasse was the only thing that worked. Also had an imprint of a leave on the hood. Nothing would get it out except Klasse. Good ****!

Buy glass stripper, many different brands but will resolve the issue
