How to remove brown spots from mirror?

Question

I know the black marks in 2nd photo are damage to the silvering. You can see scratches on the backing and light goes through. But what are the brownish marks and can they be removed? There's no marks on the backing behind these. Thx!

I think the brown marks are the beginning signs of silvering as well. With older mirrors, I am not sure there is any fix for that, other than having the mirror completely re-silvered.

You could try one of the spray on mirror finish paints, it does a great job of turning clear glass into mirrors

I would need to strip off the backing paint though cause it is intact behind the brown spots. Worth trying?

You have to remove the backing and repaint it.

William · Answer

Michele is correct. The silvering is going bad. Moisture got behind the paint and is attacking the silvering. You can strip the paint and silvering with Citristrip paint stripper down to the glass. Use Rustoleum Mirror Finish. then flat black paint to protect it. Make sure the glass is super clean before applying the mirror finish.
