Dustin try the Rain-X 5071268 2-in-1 Glass Cleaner and Rain Repellant - 23 oz. (http://www.amazon.com/gp/product/B000NWJJLG/ref=as_li_tf_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B000NWJJLG&linkCode=as2&tag=affiliatechie-20)http://www.assoc-amazon.com/e/ir?t=affiliatechie-20&l=as2&o=1&a=B000NWJJLG you can use it on all types of glass and I also use it for cleaning the sinks. Just spray or wipe the glass treatment on then wipe it off with a microfiber cloth. I use a squeegee to take off the water after showering to keep the soap scum from building up again. It will repel water for up to six months.
