Hi all,

I purchased a 2005 GPW that probably had a good rain session and never wiped off and was garaged for years. It has less than 20k miles but there's water stains on the side windows and also some on the front windshield. These spots are the worse my detailer ever has seen and he tried to remove them with his vinegar methods for roughly 2 hours and it didn't help!

I attached 2 pictures but it looks worse in person IMO... any ideas on what methods I should use or what product I should purchase?

 

Steel wool works. Try an inconspicuous spot at first, just keep it wet and don't force it.

 

there is glass polish as well.

 

I would use a fresh straight razor blade and some windex. Whenever I have some serious stuff to get off glass it works...should do the trick here I would think.

Thanks for the recommendation guys, I'll try it out when I get back in town next week

Googled glass polish and this came up...

He contradicted himself by saying NOT to get it on the paint and then he went ahead and said it was okay to be on the paint what a professional haha

 

Do not use steel wool; it WILL scratch. Ever hear of someone using steel wool on glasses, camera lenses, or scopes?

You want to chemically remove the calcium carbonate and use a non scratching mechanical means of removal. New, clean razor blades work well as do non abrasive pads.

One good last ditch product to use is Bon Ami - original forumula in the red can with "1886" on the label. They make a similiar revamped formula too but it should not be used on glass. Its cheap and works. Make a paste and go for it.

You can find it at Sears, Ace, Osh, etc. Mainline stores have the newer formula. You will have plenty left over to do your appliances and grill.

Another excellent product is called Bar Keepers Friend. It's similar to what cosmomiller recommended, only a finer powder. Always wet the area to be cleaned and follow the directions for use. This works on a whole myriad of materials for cleaning and polishing.

Thanks to you and cosmomiller for the product recommendations, especially being helpful that it's available at local stores. I'll definitely give this a shot! What type of cloth should I use to apply the Bar Keepers Friend on? Microfiber? Found this link and he seems to approve of the product as well http://e-bookssite.hubpages.com/hub/remove_stains

 

Just youtube'd it and found this, looks promising! Will try it this upcoming weekend and let you guys know how it goes!

You can use steel wool, car care professionals do it all the time. The trick is to use the proper type of steel wool, I recommend 0000 grade.
