Making your own heavy-duty fiberglass scouring cleaner is simple and effective. This tried and true old fashioned recipe uses whiting powder, an ingredient commonly used in homemade household cleaners.

Whiting is a very fine powder composed mostly of calcium carbonate. As a mild abrasive whiting powder can also be used shine stainless steel, marble, glass, silverware, copper as well as other nonferrous metals.

As mentioned, it’s a common ingredient in homemade household cleaner recipes and a little goes a long way.


Fiberglass Scouring Cleanser

You’ll Need:
1/2 cup shaved or powdered Ivory Soap
1 Tbs borax
1 1/2 cups hot water
1 T. whiting (plus up to 2 more teaspoons, as needed)

In a large plastic bowl, mix soap and borax into the water until dissolved.

Add whiting gradually, checking the consistency and degree of abrasiveness after each addition. Transfer the mixture into a squeeze-top container, such as a plastic condiment bottle. Repurpose a mustard or ketchup container for this, just be sure to label it well!

Squeeze some of the cleanser onto a damp sponge or lint-free cloth and scrub gently. Rinse and dry.

  1. The whiting they are referring to is Whiting Powder. It’s a very fine white powder slightly abrasive composed mostly of calcium carbonate. Whiting Powder can also be used to shine stainless steel, marble, glass, silverware, copper and many other non ferrous metals.

    I buy a pound of at a time on amazon and it lasts a very long time, it’s pretty cheap and as you can see from the recipe a little goes a long way. You can get it here.
