Diluted vinegar, liquid dish soap, baking soda and diluted bleach are effective acrylic tub cleaners, according to Tub Liners Direct. Windex also cleans and shines acrylic tubs.
Acrylic tubs require frequent cleaning with products that do not damage the sensitive material. These tubs cannot tolerate abrasive cleaners, brushes and scouring pads. Cleaners containing alkaline solutions often fade colored acrylic surfaces and may cause surface cracks. Washcloths and soft rags are the best cleaning utensils for acrylic tubs, according to Ask The Builder.
Waxing the sides of a clean acrylic tub promotes a shiny appearance. However, waxing the interior is unsafe because it creates a serious slipping hazard. Wiping the interior with Windex is a safe alternative.
