Cleans microfiber couches!!! I tried using rubbing alcohol and windex. Neither of them worked for my microfiber couch. Wether you have dogs or not this will work. The sponge is also essential because it has the scratchy surface that rubs the dirt up and the sponge that absorbs all the dirt underneath. Both of these items can be purchased at Walmart. I have tried many things and this has been the best at getting my microfiber couches clean.
