Not bleach. Bleach water. 10/1 water to bleach.
Plenty of contact time.
But if I were doing it, I would try mouthwash first

I bought a treadmill on ebay. It's exactly what the seller said it was
and
is in great shape except.......... the seller must have stored all his
sweaty dirty laundry on the thing. The tread stinks like BO. I've
tried
lysol and fabreeze and it's done nothing. Any thoughts on how to get
rid
of
this, it's stinking up the house!!! Thanks.

wipe it down with bleach
