Review on Sandpaper LotFancy Assortment Automotive Polishing by Daniel Mandal

These are the only items I will use to clean accumulated soap scum and hard water stains from my glass shower enclosure. It's rough enough to get the job done, but soft enough not to scratch the glass. When we showed our most recent home (sold last August) we received many compliments on how clean the windows were. I moved to another house and it was the worst thing I have ever seen. Twenty minutes later, the glass looks just as good as it did at my last home. In any case, use 2500 grit - there is less risk of scratches.
