I have started using Febreze Odor Eliminator. We are a few loads and a few nasty workouts in and so far I am really impressed with it! I have been attending hot yoga in my favorite lululemon and they are still fresh as can be!
It is a laundry additive, so you still use your detergent, which I switched to free and clear, and add this into the wash. It was a bit cheaper than the pods we were using before and its going to last a bit longer.
