Cleaning my shower doors is a dream. I use a squeegee or just wipe them dry. I have zero spots. I am truly amazed at how maintenance-free they are.

How our glass coating technology works

At a microscopic level, glass is extremely porous. As a result, minerals from hard water, soap scum, and other contaminants can easily penetrate the surface, causing unwanted stains. DFI’s protective coatings chemically bond to the glass, creating an ultra-thin barrier that seals the surface and provides a wide array of benefits.
