Gerrii Hot Tub Spa Balls 12-Pack 3" Floating Scum Absorber Sponges — Reusable Oil-Removing Film Cleaner

Gerrii 12 Pack Hot Tub Spa Balls are 3-inch floating sponge scum absorbers that soak up oils, lotions and surface film to keep pools, hot tubs and bathtubs clearer between cleanings.

These lightweight, reusable sponge balls are designed to sit on the water surface and attract greasy residue and debris so you don’t have to constantly skim. Each pack includes a dozen compact sponges that expand after unpacking and can be squeezed, rinsed and reused. Their neutral shape and soft texture let them work in hot tubs, swim spas, plunge pools, and large bathtubs without scratching surfaces.

How do these spa balls remove scum and oil from the water?

The Gerrii sponge balls are made from absorbent foam that preferentially takes up hydrophobic oils and lotions from the water’s surface. As they float, the material wicks and traps oily film so it collects in the sponge rather than clinging to tub edges or floating on top.

• 3-inch diameter sized to contact surface film efficiently
• Sponge material attracts oil and greasy residue
• Floatation keeps them in the film layer where scum forms
• Reusable: squeeze out contents, rinse, and dry between uses

Will they fit and work in my hot tub, pool or bathtub?

Yes — the compact, buoyant design lets these balls move freely across spa and tub surfaces and into corners where scum accumulates. They are appropriate for typical residential hot tubs, inflatable and above-ground pools, and bathtubs used for soaking.

• Approximately 3 inches across — small enough for jets and filters
• Lightweight so they don’t interfere with water circulation
• Safe on finished surfaces when used gently
• Can double as casual pool or bath play balls

How do I use and maintain these floating scum absorbers?

Using them is straightforward: place one or more sponges on the water surface and allow them to drift over areas with visible film. When saturated, squeeze the absorbed oils into a waste container, rinse under running water, let air-dry, and store until next use.

• Remove from vacuum packaging and allow sponges to expand
• Place in water—use multiple for larger tubs or pools
• Squeeze, rinse, and air-dry to restore absorbency
• Replace when foam shows signs of wear or reduced uptake

Who is this for? Gerrii’s 12-pack of 3" spa balls is made for homeowners and renters who want a low-effort way to reduce surface oils and floating scum between routine cleanings. They suit frequent bathers, families with kids who use lotions, small pool owners, and anyone who prefers to maintain a cleaner water surface without chemicals or constant skimming. Because they’re reusable and compact, they’re also convenient for those who travel with inflatable tubs or maintain spa facilities with light daily use.
