So I decided to frost the glass on my kitchen cabinets using (first) Rustoleum's Frosted Glass Spray paint, and then over that, I brushed Liquitex artist's matte medium (post is here: http://lipstickandabradnailer.blogspot.com/2012/07/how-to-frost-glass-cabinets.html).
Then I decided that I didn't want the frosted glass anymore. It's just that my kitchen has a traditional look to it, and I thought the frosted glass made it look more modern, and thus out of place. Here is how it looked:
So the Rustoleum Frosted Glass spray paint and the artist's matte medium are both removeable. If you have used etching cream to frost the glass or if you have bought frosted glass that was professionally frosted, that is permanent, and this method of removal will not work for you.
I just left the cabinets hanging, and I sprayed water on the glass (I had frosted the back of the glass on the inside of the cabinet) to soften the frosted coating some. I also read somewhere that spraying water on the glass beforehand lessens the chances that you will scratch the glass when you use the scraper. Then I bought this handy dandy glass Stanley glass scraper at Wal-mart for less than $3. It has a wide blade.
The wide blade worked so easily to remove this coating. This did not scratch my glass (which is not safety or tempered glass, by the way). You have to press down firmly, though, to get it to come off well. The coating that comes off is kind of like plastic wrap. Here is a better pic of it:
It came off very easily with little mess. I recommend using a removeable method if you are going to frost glass, since you may change your mind someday and not want it anymore or at least not want the pattern you originally had on it. Here is my glass after I removed all the frosted glass coating:
Much better until I decide what I want to do with the glass!!
