- 1). Put on rubber gloves and protective eyeglasses. Pour the Borax into a bowl.
- 2). Moisten a sponge with vinegar. Firmly press the damp sponge into the bowl with Borax. The Borax will stick to the sponge.
- 3). Scrub the sulfur stains with the scrubbing side of the sponge. Repeat the first two steps if your sponge dries or runs out of Borax.
- 4). Scrub until the sulfur stains are no longer visible. Rinse well with hot water.
