Thanks for all the info. I did go to a laundromat and used a double load washer. I used an organic, dye-free, scent-free, chemical-free detergent in cold water with three color catchers and partially dried it on low. I finished drying it draped over two poles in the backyard in the shade. No problems whatsoever. I will, however, get into the habit of washing my yardage beforehand. Thank sgsin.
