Staining on glass

Hi, i have made my 6th copper foil project and have a problem with the last one that I didn't come across with the others. I have used reclaimed glass in this project and I've found that it has picked up some staining..I assume from the patina, i am wondering if there is something I could use to clean it off, it seems to scratch off but as its right in the corners it it quite hard to get to.It has a dirty appearance that is a bit disappointing. I have already stripped it back once and reapplied the patina, which did seem to get rid of a lot but I'm not really sure if I can fix it by doing this again. Any suggestions would be appreciated.


Tooth paste works well for removing most stained.
The Mr Clean Magic Eraser will remove some stains also. If anyone reading this has had luck with anything else, please tell us about it in the comments section below.

Patina Stain on Glass


I have several panels with patina stains on the glass. I thought I'd have to live with it. Then I joined Warner glass chat and asked. Someone referred to your site on copper finish so I thought I'd check you out.

Novacan Stain Remover and toothpaste were advised for me to use. Do you have a suggestion?
Also, you said some people use white vinegar or salt in the black patina, do you?

I've been making stained glass for 3 1/2 years and I LOVE it. I'm going to put them in a business soon to see if they will sell.

Thank you in advance for your help.

Hi Jane,

Have you tried the toothpaste? It has worked very well for me. Something else that should work is the Mr Clean Magic Eraser. I've never used it on patina stains since I haven't had any to try it on. However, I've never found a stain that it didn't remove, so if you have one, give it a try and let us know how it works.

I very seldom use black patina...I love the look of copper, but when I do use black I put salt in it. It make the black darker.

I can't guarantee this, but I believe that waxing before you apply the patina protects the glass from stains. I haven't had any patina stains since I started waxing first (which is part of my cleaning and applying patina technique).

Good luck with the sale of your stained glass creations,

glass stained after soldering and applying patina

by kris burrowes

After soldering and applying patina the glass has an iridescent look to it that cannot be removed. mostly happens to red glass. I clean immediatly after applying.


Try cleaning it with toothpaste. Don't laugh, it usually works. I've seen it take off stains that I thought were permanent.
