A scrubbing sponge is perfect for cleaning grout, tile, shower walls, glass, mirrors, windows, and other hard-to-reach surfaces.
How can I get my scrubbing sponge wet?
There are two ways to make your sponge wet. First, soak it in a bucket of water for 30 minutes and then wring it out. Second, soak it in the sink for 3-5 minutes.
