One of the best things you can do to protect your glass is to use TPC surface protector. When we install your glass, we do the first coating, which typically lasts 3 or 4 months, and then you can purchase a container of the product and apply it yourself.
This is a very thin polymer coating that is applied as if it were a polish and it laminates it to become stain-repellant. This minimizes fingerprints, mildew and scum from building up.
