Both of us were smoking in the car the
whole way down as well as back, not to mention that the outside of the
windshield was collecting bugs at a tremendous rate... anyway, the drill
was to stop for gas right before it got completely dark, and clean the
outside of the windshield with the gas station squeegee and then wipe
both inside and outside of glass with these glass wipes (they come in a little
plastic container like baby wipes) et voila, crystal clear glass and
no glare from oncoming headlights. I liked them so much I'm going to go
buy my own container so I can try it on my own cars (one of which has a
rear window I just can't seem to get clean by conventional means as it's
huge and the PO was a heavy smoker, the other one is clouded from what I
believe is outgassing from my new interior.) Once you wipe the windows
down they clear themselves in a few seconds, no need to polish with a
paper towel. If you drive a car with the windshield close to you, it's
possible to do the inside while driving should you forget to stop before
dark. Two thumbs up! And I usually avoid Armor All products like the
plague...
