Mixing the Muriatic Acid
Now, let’s mix the muriatic acid. Follow these steps:
- Take a plastic container.
- Pour one part muriatic acid.
- Add three parts water. Always add acid to water, not the other way around.

Applying the Muriatic Acid to the Mirror
Now it’s time to apply the acid. Follow these steps:
- Put the mirror face down on a safe surface.
- Spray the back of the mirror with the mixed solution.
- Watch closely. The silver will start to bubble.
- Let it sit for a few minutes.
Do not leave it too long. Check every minute. You want the silver to come off, but not too much.
Removing the Silver
After a few minutes, check the mirror. If the silver is bubbling, use a rag to wipe it off. If it is still hard, spray more acid and wait again.
Once you remove enough silver, wash the mirror. Use lots of water. This stops the acid from working. Rinse it well. Make sure no acid is left on the mirror.
Finishing Touches
Now that the silver is removed, let’s finish the look. Here are some ideas:
- Let the mirror dry completely.
- Consider adding a coat of clear sealant.
- This helps to protect the new look.
