Here are questions related to Fixing Black Spots on Mirrors.
I have a black, rust like stain that has appeared on my bathroom mirror. It doesn't seem to be on the surface of the glass, but seems to permeate right through. Any ideas what caused it and how to get rid of it?

The posters below have it correctly, the "silver" is coming off from the backing of the mirror. You can try and avoid this problem by never spraying a mirror with cleaner to clean it but by spraying a paper towel or whatever you use directly and then wiping off the mirror. Moisture collects on the mirror and can seep through if you spray window cleaner directly on it.
What causes a black rust like stain to appear on my bathroom mirror? It seems to permeate right through the glass.

I have only ever seen this problem with very old mirrors. Is this a new mirror, or an antique one? I agree that it is likely the backing coming off.
I spray all my mirrors directly, and have for years. I don't have a problem, but thriftyvicki may be right. I don't spray so much on that it drips all over.
The edge of my bathroom mirror (currently hidden by the frame) has a small nick to the silvering on the back. I am afraid it will grow/spread with time if left "untreated" creating a black spot on the visible portion of the mirror. What can I safely seal/coat the nick with now to keep it from growing/spreading with time?

My shower door, which is also a mirror, has a black stain that is growing. It started out about 1 inch X 4 inches, and in about 6 months, spread to about 12 X 12 inches.
I realize it can't be fixed, but is there some way it could be stopped from spreading any more? I am very near sighted and need to stand close to the mirror to do my makeup. The mirror over the sink is too far away for me to use without glasses.
I'd like to stop the spreading if it is possible. Would just resealing it all around do any good?

Hi, Everyone! I came across this forum while I was surfing re mirrors. Ironically, only yesterday I placed an order with Amazon.com for a spray product by Krylon (Krylon #9033 Looking Glass Mirror-Like Paint) which is supposed to enable an ordinary piece of glass to be turned into a mirror by simply spraying the glass after proper cleaning. Apparently, this product is not simply a shiny or chrome paint. Reviews were consistently marvelous.
I do not believe this product will solve the root problem of a mirror being continuously subjected to moisture. However, I think it might help in other situations. I hope to incorporate Krylon's product into my art.
Here is the direct page via the Krylon URL
I also loved the projects pages for their products.
Will update you after I give Krylon Looking Glass a try!
I have a problem with black spots on edge of a mirror. If we stop using liquid detergent on the mirror will the black spots cease growing in size and we can frame the mirror to conceal the spots?

Or, you can embellish the mirror. Is the frame ornate or country? If you look at the mirror from across the room, what do you see?
Could you enhance with some lace, fabric, buttons, or glass paint and faux metal work?
If it's not the large wall kind, can you make it into a serving tray for tea cups, jewelry, or to display a collection?
If you love the item, you can fix it. There is no reason to get another mirror unless you break it. If nothing else, give it away and someone will be thrilled to have it.
I have an old mirror which has black around the edge. Can this be repaired?
You can find several videos on YouTube with detailed instructions for removing oxidized silver from a mirror, preparing the mirror for a new silver plate, and the actual silver application. It's not a task for the average 'do it yourselfer'. You may want to have it done professionally. The process is called 'resilvering a mirror'.
Thrifty Fun has been around so long that many of our pages have been reset several times. Archives are older versions of the page and the feedback that was provided then.
I need some advice please on how to remove black spots on my bathroom mirror. I am unable to remove the mirror from the wall.
Thanks in advance,
Andrea from London
Use stickers on the "good side" to cover up the black spots.(01/15/2005)

My bathroom mirror's edges are fading. It has black splotches on the edges. What I can do to hide those splotches, maybe frame it? Any suggestions, please.

* Here's a temporary solution for all of you renters out there. Take a grapevine wreath and soak it overnight in plain water in the bathtub or a storage tote. When it's been soaked in water overnight the vines on the wreath will become pliable. Now unwind the vines from the wreath and staple them to the bathroom wall around the edges of your mirror. Then the next day after the vine has dried out a bit, hot glue silk ivy or grape leaves and vines to it. Making sure to cover the staples with silk leaves to disguise them. This twining ivy or grape vine will look very real because of the real wooden vine. Be sure to place the ivy leaves so they cover the black spots in the mirror. I did this in a rental house and it turned out beautifully!
* Another tip: If you can get the mirror down, they make a silver mirror spray you can spray on the back. This mirror spray is made to turn glass into a mirror. You first clean the glass with rubbing alcohol, then spray on the silver mirror finish behind the glass. (07/27/2008)
