Scumbug

It works! How else can they charge $8.95 for a sponge!
But not any sponge.
I've tried everything and the unique material of this foam devours Scum, Slime & Grime from pools and spas.
Helps eliminate scum line formation.
Absorbs 40 times it weight in body oils and lotions.
Wash it out under the sink when it absorbs the gunk in your tub.
