I haven't had the stinky bike clothes problem, maybe because I launder my riding clothes immediately after de-biking (is that even a word?).

However, I will sing the praises of Oxi-Clean. The stuff is a fantastic stain remover and seems safe for fabrics. My kid enjoys all kinds of arts and crafts, not to mention all kinds of outdoor activities. Her clothes present challenges every laundry day - stains, paint, egg dye, grass stains, mud, grease, bike lube, etc. I never know what I'll find. As a result, I have found soaking clothing in Oxi-Clean will take out stains that laundry detergent alone won't budge. In extreme cases, I have left some of her stuff soaking in Oxi-Clean for a week, sometimes changing out the mixture half way through. The clothing is undamaged and usually the stain is gone even before I throw the item in with the regular wash.
