Acrylic Composition
-
Acrylic is a nonporous plastic commonly used in kitchen and bathroom sinks and tubs. This synthetic material is durable and easy to clean.
Cause #1: Hard Water
-
Hard water is common throughout the U.S. and is especially prevalent in homes that draw water from wells. Minerals in this water create limescale deposits that naturally yellow acrylic surfaces.
-
Cause #2: Bathroom Cleaners
-
Some bathroom cleaners are too harsh for acrylic surfaces. Consult the manufacturer of your tub for approved cleaners to ensure you don't permanently damage the acrylic lining.
Treatment
-
Remove yellow stains caused by hard water deposits with Lime-Away or a vinegar and water solution. A mild soap and water solution also works for general cleaning. If the yellowing is the result of trying to clean the tub with a harsh solvent, it might have caused irreparable damage to the acrylic surface.
Prevention
-
In you have hard water, install a water softening system in your home. There are a variety of systems available. Use mild bathroom cleaners made especially for acrylic bathtubs. A white vinegar solution or a store-bought detergent made for acrylic or fiberglass tubs are both good options to prevent discoloration.
