I'm not trying to be rude or anything- but think of how much the water and the soap would cost compared to just cutting up another old t-shirt for more rags. I know where I come from I'm always stocked with new t-shirts from vendors, charity races, company events, and school stuff. Because of this- I never think twice about throwing out a rag after using it with mineral oil or danish oil- That is, after I have hung it out to dry for a few days. -
