Size 9" X 4" X 2" green microfiber 2 in 1 knobby sponge with scrubber. This microfiber sponge will lift and trap dirt and moisture, leaving a clean, dry and polished surface. They are safe to use on all surfaces around the home, car, RV, motorcycle, aircraft, or boat. The microfiber covered sponge requires little water, reducing waste. In addition, this microfiber sponge is especially adept at cleaning without the use of chemicals. Use it wet and it will absorb about thirty times its own weight in water. Microfiber works by attracting dust and other contaminants like a magnet and trapping them within its very fine microscopic filaments. Due to their superior quality, these microfiber covered sponges can be washed and reused hundreds of times. Care instructions: Machine wash. Tumble dry low, and do not iron. Do not use fabric softener as this would clog the microfibers and reduce performance. Do not use chlorine bleach. Wash with other non linting materials to maintain proper dirt-gripping properties.
