I am trying to keep my windows looking clean. So I picked up some Stoner's invisible glass and two microtex MF glass cleaning towels. I sprayed the cleaner on the glass, wiped, the buffed it dry with the second MF. I did that for the windshield and the back window. I sprayed the cleaner on the first MF to clean the side windows. My question is can I use the stoner's cleaner on the inside of the windows? On a side note I l cleaned all the window, went to work, it rained.
