Scumbug Oil-Absorbing Sponge effectively removes oil, grease, scum, slime, and grime from pools, spas, and other surfaces. These sponges are designed with high absorption capacity, making them ideal for use in kitchens, swimming pools, and spa maintenance. Each sponge measures approximately 11.5 x 11.5 x 2.5 cm, providing a convenient and efficient solution for cleaning and upkeep. The sponge helps capture surface contaminants in water, aiding in the maintenance of clean swimming pools, hot tubs, and jetted tubs. To use, simply place the sponge in a filled pool or tub. When saturated, squeeze out the absorbed oil, rinse with water, and reuse. For best results and extended lifespan, avoid exposure to direct sunlight and do not use liquid detergents, as they may degrade the material. Rinse with clean water only and store in a sealed bag to maintain effectiveness. Package includes 16 oil-absorbing sponges.
