Same. Sometimes I wash all the towels and sheets together, and other times I toss in jeans and sweatshirts with towels.I use it twice then it goes in the basket to be washed.
Okay -- ready for the flames. Grubby person here, I guess. We go for at least a week, longer in the winter because we don't shower every day. Philosophy is that one is clean when one uses the towel, right?
I think I'm in that area.No set time, but I usually use a towel at least 3 or 4 times before washing.
