for Hot Tub to Soak Up Oils, Original Oil-Absorbing SpongeBall, Alternative for Scumbug, Ball and Scum Star, Spa Cleaner Sponge for Swimming Pool, Jacuzzi and Hot Tubs, 4 Balls

Excellent addition for any hot tub. Does a great job of soaking up body/ lotion oils from the hot tub water. Water stays crystal clear.

This works. Had granddaughter swim party with a lot girls with suntan lotion on them the pool was oil. I put them in and it helped clean the suntan lotion up

They don't hold their shape. I squeezed them in my hot tub and they still look like I squeezed them.

I forgot to save the one I just threw out but it has a scum ring on it so you know it works. Also don't squeeze them as they don't come back in shape, just let them be.

Work well

They surely do absorb plenty of oils for a Spa. However, you can't really wring them out as the scum gets all over your hands. I tossed mine out.

These are great! They get the extra soap scum and oils off the top of the water. Really helped with the foam issues we were having. They are washable. Just make sure to let them dry out and expand before putting them back in your spa. Would buy again.

Best replacement for scum balls. works very well in hot tub
