How to look after your acrylic bathtub properly! household remedies protect the environment Rinse your acrylic bathtub with hot water after every bath and dry the surface with a cotton cloth. Acrylic bathtubs are naturally resistant to different kinds of dirt due to the material. Usually, simple wiping with a soft cloth or sponge is enough to clean it. To remove greasy or oily deposits, it is best to use washing-up liquid, liquid detergent or soft soap. A paste made from water, tartar and hydrogen peroxide helps in extreme cases. Under no circumstances should scouring powder, abrasive cloths, scouring sponges and microfibre cloths be used on your acrylic bath. Otherwise, this results in extremely fine scratches that attract dirt and limestone deposits. If the tap water in your region is very hard, then remove limestone residues carefully with vinegar or citric acid diluted in water. Rubbing with lemon peel also results in a lustrous shine. However, if your acrylic bathtub is scratched, then we recommend treating the scratches with our acrylic polishing kit.
