Many sponges are dishwasher-safe and can be sanitized in the dishwasher or in the microwave. They also rinse clean under tap water and are described as resisting odors and mold for months.
The results include liquid dish soaps and refillable spray cleaners, dual-sided scrubber sponges, and a water-activated cleaning paste.
Descriptions emphasize grease-cutting and film removal (including milk/formula film and odors). Some spray formulas claim fast grease removal (one notes up to 99% in one spray), and the paste or cleansers are said to lift baked-on residue and limescale.
