When you work with Rex Glass & Mirror, our commitment to you does not end when the project ends. We provide a range of aftercare services, and we pride ourselves on our quality CLEAN, SEAL, SHINE (“CSS”) maintenance products. Our aim is to ensure that your Rex glass products are looking brand new for years to come. We highly recommend maintaining your products with our CSS Limescale Cleaner, CSS Glass & Tile Sealer, and CSS Metal Shine.

Follow these guidelines to keep your glass, mirrors, and showers looking like new.

Shower Door Glass

Caution: abrasives and harsh cleaning products will damage the glass! Never use scouring powder or pads, acid based cleaners, or sharp instruments to clean the glass as they can permanently damage the glass.


There are many glass cleaners on the market, however, a good many contain ammonia. Although a good cleaning agent, ammonia can harm metal finishes. We recommend the use of an ammonia free cleaner as well as the use of a squeegee type cleaning tool right after showering to prevent soap and mineral build-up. Never use commercial strength cleaners or products like Lime Away or CLR.

Brass & Aluminum Hinges and Hardware

Most of our decorative hardware finishes receive a protective finish of baked enamel clear coat, or a lacquered finish. The intent of the coating is to protect the finish from oxidation during shipping and storage. Once the hardware has been installed, environmental conditions such as air quality, climate and frequency of use will initiate the aging process of the finish. There is no defined time period for the life of the finish. We recommend our CSS Metal Shine to clean and maintain your shower enclosure hardware.

Molds / Mildew

Molds and mildew are very common in buildings and homes and will grow anywhere indoors where there is moisture. When your shower door was installed, it was caulked in strategic areas for the sole purpose of preventing water from leaking outside the enclosure. The caulking will discolor over time depending on the overall moisture environment in your particular shower. It is not an indicator that your shower has been caulked or installed improperly and should not be considered a health hazard or warranty issue.
