How do you wash your cheese?

I am washing some cheese wheels with beer or mead. Glengarry used to carry sponges for washing cheese, but they discontinued and now only carry brushes. I cannot find sponges at other cheesemaking suppliers (New England Cheesemaking, Dairy Connection) or dairy processing suppliers (Nelson Jameson, Weber Scientific). Supermarket sponges might be treated with antimicrobials (like triclosan), so I want to avoid them. Do you wash any of your cheeses? If so – what do you use, do you like it, where to you get it? Thank you for any information!
