In contrast to traditional sponges, the Meguiar's Lambswool Wash Mitt features a deep lambswool pile that enables particles of dirt to be drawn safely away from surfaces that are being washed. Furthermore, because this pile is quite loose, the same particles of dirt can be rinsed out very easily after each panel is washed. These characteristics make the Meguiar's Lambswool Wash Mitt a very safe choice for hand-washing duties, particularly when it is used with the two bucket method and a good quality shampoo. However, note that the mesh side should only be used on glass, as it's too coarse for safe use on bodywork and trims.
