There are several glass treatment options out there that can make it easier to keep your glass shower door clean. Treatments can help keep soap scum, corrosion, and pesky little fingerprints at bay. You might pay as much as a 30% upcharge on the price of your glass shower door to add a protective coating.
Even with a protective coating, you have to clean your shower. If you are diligent about wiping down shower walls after use and giving the glass a more thorough cleaning every week, you can likely save money and skip the added glass treatment.
If your shower endures heavy use from multiple family members and guests, a protective coating can make it easier to keep the glass spotless.
