Here are the steps:
1. Prepare a solution of water and ammonia in a spray bottle.
2. Spray the solution on the frosted glass surface until it is completely wet.
3. Let it sit for about 15 minutes.
4. Wipe off any excess when it is dry with a paper towel or cloth type material to avoid streaking if you’ve sprayed too much liquid.
Ammonia will remove the frost from your windows when it is very cold outside. The solution helps prevent anything from sticking to the window during the cleaning process.
So this is how to Clean Frosted Glass.
