Bathtubs are constantly in contact with dirt, soaps and body oils, which quickly stain and deteriorate their appearance. Plastic bathtubs are easy to clean and maintain, as the plastic is a non-porous surface that allows you to remove stains and residue in a few easy steps. The key is to act quickly to remove the stain, then implement a regular cleaning routine that will break apart residue as it develops.

  1. 1

    Pour equal parts of powdered dish detergent and baking soda into a bowl.

  2. 2

    Pour in water slowly, stirring the powdered ingredients until you have formed a thick paste.

  3. 3

    Pour plain powdered dish detergent onto the stain, then scrub with a damp nylon scrub brush. This will loosen much of the excess residue.

  4. 4

    Rinse the area, then spread a thick layer of the paste onto the stain. Let sit until dry.

  5. 5

    Scrub the dried paste away with a nylon scrub brush, then rinse the area. Repeat the stain removal process until the entire stain has been removed.

Tips and warnings

  • Fill a spray bottle with 3 cups hot water, 1/4 cup powdered dish detergent and 1/4 cup baking soda. Shake the bottle to combine ingredients, and use as an all-purpose cleaner for your shower. The hot water will dissolve the powdered ingredients, the dish detergent will cut through soap scum and the baking soda will add an extra cleaning and deodorising element.
