Abstract

A relatively thick sponge has a washable microfiber cloth that removably covers at least a portion of the sponge, and is particularly well adapted for automotive use by virtue of a microfiber pile on the cloth. Preferred cloth coverings have microfibers with a length (pile height) of between 0.5 and 0.11 cm, and more preferably between 0.7 and 0.9 cm. The sponge can be any suitable size and shape, but is preferably dog bone shaped, having a length of at least 10 cm, a width of at least 6 cm, and a thickness of at least 2 cm. The cloth is preferably sized and dimensioned to completely enclose the sponge.
