The foggy Glass effect is very useful. It can take a plain lantern with a flicker flame bulb and give it a realistic effect. It can also make details unclear and leave more up to the imagination.
Water Salt Based Solution - This will give a frosted look to glass and plexi glass.
You should only do this process to glass that you plan on keeping fogged. Since this is a salt based effect it will wash off. However it is not easy and you may find yourself with a razor blade cleaning it off the glass.
Mix the water and salt together, let the salt dissolve into the water.
Now apply the solution to the glass you want to fog. The target glass will just look wet but when it dry's all the salt will stay and the water will evaporate. Repeat the process for better results. * Epsom salt can be bought at your local drug store
