The EuroScrubby is safe for cleaning just about anything and lasts four months! You can wash it in the top rack of the dishwasher or with your towels (not delicate clothing) in the washing machine. Designed in Canada and made in Europe, it's a cleaner and more earth friendly option than sponges. Use on nonstick pots and pans, glass and ceramic cooktops, bathroom porcelain and tile, garden tools, and more! Do not use on cars. Approx. 5" X 6"
