Acrylic bath

A soft plastic surface that scratches, crazes with solvents and is damaged by bleach and strong disinfectants, so the safe product list is very short.

General rules for acrylic bath

The list of things not to use on an acrylic bath is longer than the list of things to use, and the short list is entirely adequate for a milk mark.

Warm soapy water and a soft cloth. Nothing gritty, no solvent, no bleach and no strong disinfectant.

That rules out most of what people reach for in a bathroom, which is why acrylic baths so often end up crazed, dull or yellowed. The material is fine; the products are the problem.

Check the label

Acrylic is softer than china and scratches easily, and UK bathroom suppliers are unusually blunt about it: never use household or commercial chemicals on it, including paint stripper, nail varnish remover, household bleach, perfume, aftershave or strong disinfectant. Warm soapy water or a mild cream cleaner is the specification.

Stains on acrylic bath

An acrylic bath is a thermoformed sheet of acrylic, usually reinforced underneath with resin and fibreglass.

It is soft

Softer than china, as suppliers put it, so scouring pads and powders scratch it in normal use. A scratched acrylic bath then holds dirt in the scratches.

Solvents craze it

Nail varnish remover, paint stripper and even perfume and aftershave attack acrylic, producing fine cracks called crazing that spread and cannot be polished out. Suppliers name all four specifically.

Bleach is excluded

UK suppliers say not to use household bleach on acrylic. It yellows and degrades the surface over time.

Heat matters too

Acrylic softens well below boiling, so a very hot cleaning process can distort it as well as setting the stain.

  2. Melamine dinnerware and staining, G.E.T. manufacturer

    Melamine manufacturer guidance that staining is caused by food left to dry on the surface and by protein and hard water minerals building up, that an oxygen releasing soak or an overnight soak in warm water with dishwashing granules removes the stains, that a non abrasive pad is used afterwards, and that bleach, green scouring pads, steel wool and metal scourers must not be used because they dull and scratch the surface.
