Squeegeeing the glass frequently, then drying with a soft cloth is highly recommended. Using a squeegee after each shower helps keep spots and scale from accumulating on glass components.
The Model Home Look also recommends cleaning the glass twice a week with a glass cleaner while following the recommendations of the Bath Enclosures Manufacturing Association (BEMA).
Avoid abrasives, bleach, acidic or vinegar based cleaners and scrubbing pads. Read labels on cleaning products thoroughly before using.
