Cleaning bath tub jets
My mom has one of those bathtubs with jets that is supposed to massage a person while they take a bath. Its got 8 holes in total, 3 on each side and 2 for the back. She's never used it before, but she hurt her arm recently and I suggested she give it a try.
But, when she tried turning it on, this disgusting green algae thing came out of those jets. Since she's hurt and I'm a good son, I guess I'm supposed to try to clean it out. But, I have no idea how to do this. There are no instructions, and I hope somebody with a similar bathtub might help.
