I wash my daughter's leotards with all her other clothes. If I see them when I'm moving clothes to the dryer, I will remove and let air dry. But I miss them allll the time. I do hand wash her competition leo but the rest are just laundry. No folding, definitely no hangers - they get stuffed into her very full leo drawer. Honestly, they are wearing just fine and I will pass them along if she every outgrows them (we're on year 2 or year 3 with some of them!).
