After getting my windows tinted I see that my windows are covered in Hard Water Spots (And yes they are on the outised - I had 3 different people confirm it's not on the inside). They are all over the windows!
I've tried everything:
- Stoner Glass Cleaner
- Magic Clay Bar
- Windex w/ Vinegar
- Undiluted Vinegar
- Bug & Tar Remover
- Lime Away
- Polishing Comound
- 3M Rubbing Compund
- Skrape them w/ a Razor Blade
- HCL (Hydrochloric Acid)

Any suggestions?

 

brillo or steel wool....try on a smalll area...

 

i ahve them on my sunroof and i cannot get them gone! i have been wondering this forever. if someone has a remitiy share please!

 

If you can't get them off with a cleaner and some scrubbing, then you should take it to a pro.

You could try steel wool, but you must use a super fine knit or else you'll remove your spots and have scratches... not a nice trade off.

Most professional detailers have an acid based hard water remover. They are pretty much only made by professional detail product companies and only sold to licenesed detail shops because they are dangerous. They are real acid's. They will make you go blind, give you a chemical burn, permately damage your window and destroy your paint if you are not careful. I've had a bad incounter with the stuff, ruined a 200 dollar pair of sunglasses and had a chemical burn on my face for 3 days, and that was just a mist. You don't want to mess with the stuff. However, it does do an awesome job at removing water marks, etching and chemical stains.

 

I tried something like steel wool, didn't seem to work...
My next step will be to take it to a pro, but I don't know if they'll be able to do anything for it. My friend, who's a chemist, brought home some hydrochloric acid and we tried that on on of the windows... Didn't do a thing.

 

Well, I'm not sure about acid's but I know that the stuff that I use contains ammona and sulfric acid. It works great even on super tough spots.

 

Maybe it's under the tints and the person who did them didn't squeeze out the water and soap like they should...that could possibly leave water marks.

 

Try using clay magic. Go up to the red bar if you have to. If that doesnt work, try using Klasse All In One with a microfiber. If that doesnt work then try it with a PC at a speed of 3 with a mild pad. If that doesnt work, break the window and get a new one

 

Try using Rain-X. Seems to take off water spots really well. I use it everytime I wash the car and now I rarely even get water spots.

 

Try CLR. I saw it on a TV ad and it works well. It took out water spots easily as shown on TV.
