How To Deal With Mirror Rusting?

If you’re concerned about your bathroom mirror rusting, there are a few things you can do to keep it in good shape.

Choose Cleaning Products Wisely

If your bathroom mirror starts to degrade, you should probably replace it. Mirror de-silvering is still possible, but it’s not a simple fix because it usually necessitates replacing the mirror’s reflective plate and sealant.

So, before you have to deal with mirror rot, it’s best to avoid it altogether. One simple method is to exercise caution when cleaning your bathroom mirror.

Ammonia-based cleaners should be avoided at all costs since they might weaken and destroy the mirror’s protective coating. Also, stay away from anything with harsh chemicals or abrasives, as these might break the mirror backing and allow moisture to seep through.

Don’t Spray The Products Directly On The Mirror

Always take precautions when cleaning your bathroom mirror. If you spray the cleaning liquid directly on the mirror, it will run down the glass and into the mirror seams and corners, harming the chrome and mirror backing. Instead, spritz the cleaning solution onto a clean microfiber cloth and wipe your mirror clean with it.

There will be no liquid gathering around the borders of your mirror this way. Keep an eye on your mirror to ensure it doesn’t get damp. Ensure that it is thoroughly dry after each shower.

Wipe Down The Mirror Every Time You Use The Shower

Another approach to prevent rust on your bathroom mirror is to keep it dry and away from moisture. If there is any condensation after you shower, wipe it dry with a clean microfiber towel. Aside from microfiber towels, a squeegee can be used to wipe down the mirror to eliminate any moisture swiftly.

Additionally, if your bathroom mirror rests directly on top of the vanity, try using a silicone strip to seal the edge of the mirror where it meets the counter. To avoid water getting into the mirror when using the faucet, you can lift the mirror. So, it doesn’t touch the vanity.

Check For Appropriate Ventilation In Your Bathroom

Another technique to keep your mirror dry is to keep it in a well-ventilated bathroom. Open the bathroom windows and door after you’ve finished showering. When mirrors are exposed to extreme dampness, their metal components corrode.

Corrosion is a problem with chrome trim and metal brackets, but mirror rot is also. Moisture becomes trapped between the glass and the shiny metal, causing it to corrode. According to the manufacturers, bathroom mirrors are more prone to rusting than mirrors in other parts of the house.

The sealants in the mirror deteriorate as ammonia eats away at them. Presto. Moisture appears to have found a way into your mirror, causing rust to form.


When it comes to rusting bathroom mirrors, prevention is always preferable to treatment. After all, once your mirror has rusted, you won’t be able to repair it yourself. You must maintain the beauty and cleanliness of your bathroom mirror.

There are just two simple ways to achieve this: control the dampness in your bathroom and use ammonia-free cleaning solutions.
