Typical materials are plastic for handles and bodies, steel or steel wool for scouring pads, foam for sponges, and clay-based or paste formulations for cleaner compounds.
Some listings explicitly warn against use on rubber and painted surfaces, copper, aluminum, wood, velvet, leather, silk, brass, clothing, and certain stainless-steel applications.
Available battery-powered scrubbers often include a powered handle with interchangeable heads (multi-purpose and grout heads) and may ship with AA batteries; some models offer pulse or continuous settings and a water-resistant assembly.
Water-activated pastes create a foamy lather when dampened and are used with a sponge or scrubber to lift grime. Foaming cleaners spray foam and often include a built-in brush head to scrub and remove stains without oversaturating fabric.
Listings show unscented options as well as products labeled Fresh or Citrus, including a light citrus scent on some paste cleaners.
