The pool, spa and hot tub scrubber brush is gentle on surfaces and great for removing scum or scale.
Barely stayed together until i finished cleaning hottub
I used this in conjunction with "ProTeam Surface Clean" and together they took care of the rough, sand paper-like calcium build-up I had on the interior. It's smooth as ever and very clean. Good as new, it did exactly what I needed!
worked as expected and easily remove scale buildup on my hot tub.....of course, now I try to avoid scale from building up
