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 stall basin. You need three products for this, a sponge, yellow is preferable, with scruffy reverse, some Comet. You can use Borax, Ajax, whatever your scouring powder of choice is, and then a bucket with some water for rinsing. Step one, you're going to rinse your sponge, get it damp. Step two, because you can't really shake the powder on a vertical surface. You kind of get in there, go up and down, make sure you get that top lip, rinse that off a few times in your bucket, and that gives a whole new meaning to museum white. That's Mark Newman-Kuzel with Maid in the U.S.A., teaching you how to clean a shower stall basin.
