Cleaning Glass of Water Deposits

[71vert340]

 I removed the stainless trim from around the windows. What do I use to remove the hard water deposits on the glass from years of rain and dirt? How do I  using something  (Lime Away) and not damage the glass and paint? Its the brown deposits along the glass edge in photo.

Ultra Fine Steel Wool works best on glass and doesn't damage the paint if you mask it off with a couple layers of masking tape....

Scrape the majority off with a razor blade...then ultra fine steel wool as mentioned

I used steel wool many years ago but found if you leave little fine particles they will rust into the paint. I use Meguiars water spot remover now. Takes a little work much like a fine cut cleaner.

 Thanks for the replies. I've been using the razor blade and steel wool. Hoping there was an easier way but I'm 95% done now. I'll need to try the Meguiars product on painted surface water spots.

We used to use metal prep, it's a mild acid, but you could also use a moistened cloth (sacrificial) moistened, not dripping, with muriatic acid in your gloved hands. Obviously you don't want it to be dripping and a quick wash with some baking soda in water finishes the job. There'll be horrified comments likely, but it works, period -AND, you'll be done in minutes as opposed to hours. Your car, your call. Good luck

 I wondered about metal prep. I have some but was leery of using it. I may try it on a little spot.
Thanks.

I've used chrome acid for hard water deposits on glass and on paint... It works well but have a second person ready to hose it off... And if there's any aluminum trim don't let the rag touch the trim....

When you start rubbing the rag on the glass or paint initially it will feel like the rag is dragging or sticking... A few swipes & it'll start to move more freely & a few more passes & it'll feel smooth, pull the rag away & rinse immediately....

When you rinse watch the water, it should sheet fully over the area, if it splotches rather than sheeting hit it again... Shouldn't take much but the water should just lay smoothly over the area...

I've never used baking soda but if it makes you feel better go ahead...

I have used a Mr Clean Magic Eraser to remove hard water spots. Worked Great
