Kitchen scrubbers are cleaning tools used to remove dirt, grease, and food particles from kitchen surfaces. They are usually made of a hard material such as plastic or metal, and often have a handle for easy gripping. The term 'SDAPSOS' is an acronym for 'Synthetic Detergent-Alkaline Phosphate-Sodium Silicate-Organic Surfactant-Sodium Sulfate.' This combination of ingredients is commonly found in kitchen scrubbers, and helps to break down grease and other stubborn stains.
