Hot Tub SERUM Oil Absorbing Sponge

The sponge acts as a magnet for surface contaminants like body oils, lotions, makeup, and dead skin cells. By absorbing these substances before they circulate through your plumbing, it prevents them from clogging your filter and forming unsightly scum lines on the spa walls.

Yes, it is designed to be reused. When the sponge becomes saturated or discolored, simply rinse it out with water or wash it with a mild soap, let it dry, and place it back into the water.

While the sponge is nearly 12 inches across, it is designed to float freely on the surface of the water. Its size is actually an advantage, as it provides a larger surface area to capture more oils and contaminants compared to smaller, standard-sized sponges.

The 3D air mesh skin is specifically engineered to increase the surface area for absorption. This allows the sponge to trap oils and debris more effectively than standard foam sponges, which often just push contaminants around the surface.

This sponge is perfectly suitable for both hot tubs and swim spas. Its extra-large size makes it particularly effective for the larger water volumes found in swim spas, where oil accumulation can be more significant.
