Water stains on sunroof

Help me out someone. How do you guys remove heavy water spots from glass moonroof? When I say heavy, I mean the thing probably has been collecting spots for about 5 years or more. :confused:
 
:cool: Didn't take any pics but will try next time, pretty bad shape, I was afraid of using abrasives which might cause hairline scratches, or would it? It was a lexus LX470, damaging the sunroof could mean "BROKE" for a month:D
 
$100 says 5-year-old water spots cannot be removed with AIO, clay, vinegar, or steel wool. From experience, you'll either have to replace the glass or deal with it. Making these spots less visible will require something abrasive. Good luck :)
 
Nonetheless, a good cleaning with AIO, clay, vinegar etc. should at least reduce the spots. If not, you can always try one of the glass polishes with a PC.
 
When using vinegar, it might be helpful to let it dwell for some time on the problem area. I have a friend who owns a housecleaning business, and he says dwell time is the key with tough stains, cooked-on food residue, etc.



I've used the Malco brand glass cleaner. It gets rid of the water spots, but it does tend to scratch a bit when excessive pressure is applied. But that was done by hand, perhaps the PC would work better, as suggested by ntwrkguy1 above.
 
Thanks guys, will keep trying. By the way, would it be possible to apply vinegar by using a rotary?:confused: Then maybe clay? I tried everything in the book, it was just too thick. The surrounding areas like the roof was easy, just used a 2500grit wet sandpaper, hmmmm I wander........ NO, NOT THE GLASSROOF:nono
 
Vinegar by rotary will sling like water. Try applying a few spoonfuls worth with a cotton ball or paper towel, then let it sit while you go work on another part of the car, come back to it in about 15-20 minutes and see how it's doing.
 
It sounds like what I would call acid rain. We take this out or off glass pretty regularly. It has to be polished out. Contact glassweld.com for some of thier glass scratch polish. Only on a sunroof will come out pretty quickly.

Please recommend a site where I can buy steel wool #0000. Also, will steel wool rust?

You can buy 0000 SW almost anywhere, hardware stores, Wal-Marts, etc. Just look in the paint dept and make sure it is grade 0000.



Oops, I just noticed you're located in the PI. Perhaps PM theveed, heâ€â„¢s located in Manila and might know of a source locally for you. I also remember an old thread where he was talking about tough water spotting, he may be a good source of local info also. Here is a link to his web-site:

Edit: I found the thread he did on water spots and 0000 SW:

And if you do have to buy it on-line here is one source (and they do ship overseas):

I use steel wool all the time for tuff stains. I disagree with not using with anything and suggest that you don't use it with water only. Two things that will work good with it are stoners invisible glass window foam or disappearing windows. Better to be safe than sorry. Scratches on Glass are worse than scratches in paint. Water doesn't have lubricity of these type of glass cleaners. As for rust, I don't know it might. It's so cheap I by a roll and break off a piece, then use it and toss it. I'd rather do that than store old pieces off SW. Make sure it's 0000 steel wool, not even 000 would be a good choice for automotive use.

BTW, window spray is the only thing I recommend you buy from this site. I've tried the other stuff and I don't prefer them. Powershine has a terrible solvent smell and an oily finish, and the tire spray is very good but only lasts on 3 sets of tires. IMO stoners is a better tire spray because it lasts longer with the same results.

Thanks, checked out the thread but most of the response was not to use #0000 steel wool for it might create micro scratches on the glass. HMmm.....but its the sunroof,...would it matter? I guess so.... I just want to do it as perfectly as possible.
