The scrub side becomes firmer in cold water for tougher scrubbing and softens in warm water for gentler cleaning.
Some bundles include a water-activated, clay-based paste that cleans and polishes a variety of household surfaces and leaves a light citrus scent. Other bundles include a gel stain remover formulated for fabrics that works on both fresh and dried stains and can be used as a laundry pre-treatment.
The paste listings specifically advise against using it on brass, clothing, copper, and stainless steel.
Listings show typical dimensions as roughly 4–6 inches in height, about 4–6 inches in width, and approximately 1.5–1.63 inches in depth.
Design features include eye holes that hold two fingers for a secure grip and a mouth-shaped slot that cleans both sides of forks, spoons, and knives. The ergonomic shape is also noted to help reach deep into cups.
The product description lists linen, velvet, microfiber, and wool as fabrics compatible with the included gel stain remover; other fabrics are not specifically enumerated.
