Fibreglass tubs are easy to clean and maintain, but they can scratch easily if you use an abrasive cleaner on the surface. Homeowners can easily repair scratches to their fibreglass tub using regular automotive polish. Automotive supply shops sell small tubs of polish in almost any colour, so it should be easy to find a polish that most closely matches the surface of your tub.

Purchase a water-based automotive polish in the same colour as your fibreglass tub.

Use the clean, soft cloth to scoop out a nickel-sized amount of polish.

Apply the polish to the scratches in a circular motion with the cloth.

Dampen the cloth with cold water and wipe away any excess polish. Allow the polish to dry according to the instructions on the container.

Apply a coat of fibreglass wax to the surface of the tub after the polish dries. You can find fibreglass wax at most marine supply shops, as boat owners often use it. Follow the application directions on the package, and allow the wax to set for the instructed amount of time before using the tub again.


Never wax the bottom of a tub.
