To facilitate the getting the clothes clean and dry, I would start washing the chlorine our during the top of the intermission. A few pieces did need to be redyed, but for the most part, the color stayed well.
Clothing was hung over fans. I eventually invested in a Dr. Dry
One of the other things I used was wool dryer balls.
I make mine by starting with crocheting the yarn. Then, I crochet the crochet. It is then tied into a knot. The yarn is wrapped around, making it into a ball. To finish, I use a wide eye needle and stitch thru. The balls are then either boiled or washed in a sanitary cycle (super hot) in a panty hose to felt.
I would put the towels and bathrobes in a dryer for about 20 minutes. The actors would come off, strip down to underwear and we would be putting the wet clothes and shoes in plastic bins and buckets, while handing off towels. Then, we put them in bathrobes (we had multiples) and Crocs. The dressers would head upstairs and I would start the wash.
