The 12pcs Cartoon Duck Pools Grime Sponges are made of highly efficient absorbent sponge material that can absorb multiple times its weight in oil, slime, grime, and other contaminants. It helps remove mud, oil, dirt, and hair that accumulate in swimming pools, hot tubs, jetted tubs, jacuzzis, and spas. By capturing debris, it prevents residue lines from forming on pool tiles or walls. This sponge can extend filter life by removing scales, slimes, grime, and oils from the water, allowing the filtration system to operate more efficiently. Simply place the sponge in the skimmer of the pool or spa, where it will absorb dirt and grease, helping maintain clean and clear water.
