Mostly the windshield has hard watermarks where wipers don't hit.
What's the best to get rid of it?


Is there even a search button on the app??? Lol or am I stupid?

Thank you

You can also do it with #0000 (FINEST) steel wool. Just wipe the glass with a damp cloth to remove any dirt and then just rub a dry steel wool on the glass. Removes 100% of water spots. Blow dry the car or wash it after, since steel wool shreds

wool can create swirl marks/scratches in the glass

#0000 is specifically recommended so that this doesn't happen. Any of the coarser stuff will cause damage. People need to read and follow instructions carefully - the #0000 is vitally important. Test in an inconspicuous area on your first time.

I've used #0000 on windshields dozens of times - no marks.

that Ceriglass polish looks more safe and does the job

Sure, I guess. I never recommended against using Ceriglass.

One thing I have learned over many years in the BMW community is that there's a seemingly endless lineup of people wanting to special order something for $20 when $0.20 at the local hardware store will do the same job...

Have you ever polished glass? It's not as easy as one thinks.

First off to the OP are you doing this via machine or by hand? If by machine you'll need the appropriate glass pads for the ceri product, if by hand give up now and just try the Steel wool 0000 with some vinegar. Also do you own any chemical paint cleaners? If so try something like Klasse or P21S paint cleaner or Pinnacle Paint Work cleanser on a white or orange foam pad and see how that improves it before buying a dedicated item you may only use once or twice.

Glass is tough to polish and often the end result is not that good. I've seen some really well known pros have a hard time getting glass polished to the expectation someone has of their painted surfaces especially if it's that neglected. I'd seriously try the steel wool then the paint cleaners first. Also the polisher being used will need to be able to really cut so PCXP's struggle with neglected glass.

You hit it on the head. A rotary and a glass pad pair with Ceriglass will do the job (eventually) but it is messy and it takes a long time. A force rotation DA would also work if a rotary is not available.

0000 wool and a vinegar solution is what I would try first. Don't worry too much about the 0000 wool scratching the glass. Glass is fairly hard. It can withstand scrapping from razor blades as well as snow/ice scrapper so 0000 should not be an issue but then I also would recommend doing a small test spot prior in working on the entire windsheild.

Good Luck.
