If you’re ever cleaning up a mess in your home or office, you know how to do it: put everything away, get a cloth, and start scrubbing. But what if there’s something stuck to the glass? How do you clean it? There are a few ways to clean liquid glass thinking putty. The first way is to use a vacuum cleaner with the hose attachment. Put the putty into the crevices of the glass and suck out all of the liquid. Then use a plunger to push and pull all of the putty out until it’s completely clear. Finally, use a dry cloth to dry it off.
