Review on Washing Machine Scrubbing Balls - 15 Pack for Tangle-Free Laundry, Washer Balls for Enhanced Washing by Wendy Harris

I bought these because I was told they don't tangle clothes and they really work! As for the other claims, I'm not sure, but they do the job I bought them for. I add a dozen to every load, either before or after loading the laundry into a front-loading washer. I move them from the washer to the dryer with each load. I've used them dry on high heat with no problems. They tend to fall out of clothes and bounce when I empty the washer and dryer, but not worth chasing after and untangling everything in the load. I have a bin on top so I can throw them away when I take them out of the dryer. The real challenge will be next time I wash a bunch of new fabrics, but I need to sew some of the stuff I already have before I buy more! I'm allergic to M/I so I can't use dryer sheets. I use balls of yarn and some plastic cacti that were given to me. They help with static but don't get tangled.
