My large mirror is cloudy no matter how I clean it. Is it the backing?

I have tried vinegar, foam cleaners, etc. Mirror is 35 years old.

  • Could be - might be going blind. 35 years is not old for a mirror but it depends on exposure. You can have re silvered, but that can get expensive.

    • So welcome! I have a mirror that belonged to my grandparents that emigrated from Austria in 1938. My mom's house was built in 1926 and I still have several of the original mirrors in that house too. Back in those days, I think they made things to last, wherein now, if something lasts 10 years, it is a miracle. Weather, location and exposure have a lot to do with it too. Hot and dry here.


      Sorry your mirror needs to come down, maybe you can get it off in one piece and maybe sell it?

    i have some old mirrors and i use a steam cleaner and coffee pot filters. the ones from the dollar tree work the best because they don't leave any lint behind. hope this helped. i also use my steam cleaner on windows, appliances, glass in picture frames, sinks, faucets, and anything i can think of!

    A mirror is just glass with a coating behind it. The quality changes with the thickness and type of glass, and the coating. Moisture between the glass and backing can degrade the clarity, as well as the hardness of the water you have, etc. MIght be time to search for old mirror projects..... Local glass shop might be able to cut you a replacement.

    The silver backing could be fading. Try to look at it from the side with a flashlight. If it's the clear glass, you can tell that way. If it's the backing, you might need to get it resilvered.
