Windows that won't come clean (SOLVED!)

[Deej101]

My non-garaged vehicle parked in a forest constantly has dirty windows, and especially hard water stains (and dog nose/mouth slobber stuff).

I've tried what I thought should be the solution: magic eraser. Nope!

Then I tried Bar Keepers Friend. YES!! Finally, perfectly clean spotless glass! Followed up with that blue & white can of spray foam window cleaner.

There are several Bar Keepers Friend products, exactly which one did you use?

Just the regular powder kind. I added some water to make a paste.

It also worked really well at removing the oxidized paint from the black trim pieces (not the rubber ones). Can take pics later.

The spray works great on glass. All their products are non toxic too if that's important to anyone.

I also like buffing with one of these after cleaning to remove any streaks...

I used polishing compound and a buffer on my moon roof and it turned out amazing!
