1. Toss plastic toys—action figures, Playmobil, dinosaurs, any dirty Smurfs—into a mesh laundry bag, and tightly tie up the top.
2. Toss the bag into the washing machine with a bit of detergent, and run the gentlest cycle with warm water. (Warning, this will be noisy.)
3. Retrieve the laundry bag, open it up and lay toys flat to dry.
