RAINFLOW 16PCS Pool Oil Absorbing Sponge – Hot Tub Scum Absorber for Pools & Spas

Overview

Meet the RAINFLOW 16-piece pool oil absorbing sponge set, a lightweight polyester sponge designed to float on the water surface and capture oils, cosmetics residue, dust, and other floating debris. By targeting surface contaminants, it helps maintain a cleaner appearance for hot tubs, pools, spas, and outdoor water features.

How it works

The sponge provides high surface area and strong adsorption, acting like a gentle surface skim that gathers floating matter before it disperses. Just place the sponge on the water and let it do the work; when it fills, squeeze out the captured material, rinse, and reuse. Note that the sponge may oxidize to a yellow tint when exposed to air, but this doesn’t affect performance.

Key benefits

• Captures oils, cosmetic residues, dust, pollen, and inorganic scum from the water surface
• Supports clearer water and a more pleasant pool or spa environment
• Lightens the load on filtration systems, helping to prevent clogging of filters and pumps
• Potentially reduces the need for frequent chemical adjustments, depending on usage and water quality
• Simple maintenance: squeeze, rinse, and reuse; regular replacement helps maintain performance

Usage tips

• Place the sponge on the surface where scum tends to gather for best results
• Avoid strong chemical cleaners that may affect adsorption capacity
• Keep a routine to replace sponges as needed to preserve efficiency

Specifications & care

Each sponge measures about 11.5 x 11.5 x 3 cm. The product is designed to preserve performance even if the appearance changes over time due to oxidation. Vacuum packing helps maintain elasticity before use; simply remove the sponge and let it rest for about 20 minutes before deployment.
