Hey there. I'm Mark Newman-Kuzel, President and CEO of Maid in the U.S.A., and today I'm going to teach you how to clean a shower floor scum. You need three products for this, three items, a sponge, a soft yellow with a scruffy reverse, some Comet, you can use Ajax, Borax, whatever your cleanser of choice, and a bucket with some water. Step one, you're going to take your product, scouring powder and lightly sprinkle that around, dip the sponge in the bucket. Use the soft side first of your sponge. This is one of the rare instances you're going to hear me say you can go around in circles instead of just side by side. Then, get some elbow grease in there. You can hear that, hear that product working. Then, what I would normally do is move to the other side of the shower or the bathtub, do the same on that side, just kind of rinse. And that, my friends, is how you clean a shower floor scum. Mark Newman-Kuzel of Maid in the U.S.A.
