I'm trying to clean white sneaker soles to restore to "unworn" condition. Have tried laundry detergent, Oxi-clean, chlorine bleach, DiDi7, Formula 409 and straight ammonia, all with limited success. Any tips?

I had some old toys and other stuff stored in plastic bins in my basement now we're moving to a smaller house and that stuff will now be stored in a different plastic container under my bed. Not sure if there was mold in the basement but if there was do you know if the mold would've affected the inside of the bins and what was inside. And would it be safe for health reasons to store in bedrooms now? Most of the toys were inside ziplock bags inside the bins also. I have ocd when it comes to things like this and I'm super paranoid about touching this stuff or having it near me.
