THis is a little different but somehow the same. Several years ago there were many (100's) Dr. Pepper soda syrup barrels that came onto the market here in New York. 30 Stainless steel, nice heavy gauge barrels. They stunk to high heaven of Dr. Pepper naturally. I and others tried all sorts of different scenarios trying to get rid of that smell. We ended up using live steam and that didn't cut the smell. That Season we filled the barrels with syrup and and sampled throughout the year. No off flavors or smells were found. HOwever, when we steamed the barrels to clean them after syrup storage, they smelled like Dr. Pepper. I ended up selling the barrels (along with a lot of other equipment) when I foolishly thought I was getting out of the syrup business. The new owner can still smell Dr. Pepper to this day.
So, the smells may be imbedded in the plastic tote forever, but, MIGHT not transfer to whatever is stored in it.
Food for thought (Not sure if pun was intended or not).
