Darlly Duck Scum Sponge - Loves the stuff you don't!
Darlly Duck, or DD as he likes to be called, is an incredibly talented fellow, he prevents scum lines from forming, which eliminates the need to scrub the acrylic shell of the spa.
He reduces contaminates from clogging your filters and if that was not enough he absorbs 40 times his own weight in oils, lotions and cosmetics.
Darlly Duck likes to float freely and clean up, when one side is dirty, turn him over and he will continue his mission.
Every now and again Darlly Duck likes to be rinsed.
We have tried these and they really work!
