Hot Tub Things® Metal Out (16 fl oz) – Spa & Hot Tub Stain & Scale Preventer

This stuff is exactly what we needed for our nw hot tub! So glad I came across it - gets rid of metals quick!

Keeps spa water clear. Filling a tub without this risks having copper fall out of suspension and tinting your spa water (and your spa) green.

good book.

Easy to use and works great.

Long story short, my toddler flushed a dish sponge down the toilet and clogged it. After it overflowed a few times I got a snake and snaked it out, finding the sponge. However in the process the metal spring from the snake left scrape marks in the toilet that would not be cleaned off easily. I got some of this, put just a little bit in the toilet and then left it for five minutes. In five minutes, boom, the scrape marks were gone.I am glad too, my wife was talking about getting a brand new toilet just cause of the scrapes.
