Super easy to clean, apply wax, and do everything in hard to reach places because of their size. Microfiber Mini Sponges are just what they sound like, a sponge covered in a microfiber towel. It's excellent for anything you would use a regular sponge for and especially wax applications. This little guy is 3.5" x 6" x 9. If you want a larger Microfiber Sponge, get the regular size instead of the Mini! Washing machine safe.
