Posted a query earlier in re to being fearful of getting stains on the mug rugs I wanted to make and received many informative responses. In the meantime, discovered a product that solves my problem and thought I might pass it on. It's called OxiClean Laundry Stain Remover". It comes in a 21.5 fluid ounce blue spray bottle. You simply spray it on, rub it in, wait 10 minutes and run through a normal wash cycle with detergent. Tried this because I had shocking pink and brilliant blue Bingo Marker stains on the sleeve of a fleece cardigan that simply wouldn't come out. Tried this product and couldn't BELIEVE they were gone. Works great on tomato products as well. So..........mug rugs, here I come!!!
