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 absorbing debris, it prevents residue lines from forming on pool tiles and walls. This sponge can extend filter life by capturing scales, slimes, grimes, and oils from the water, allowing the filter to operate more efficiently. Simply place the sponge in the skimmer of the swimming pool or spa, where it will absorb dirt and grease, helping maintain clean and clear water.
