Thank you everyone for your suggestions.  My immediate thoughts were to use a bleach or vinegar method, followed up by the dishwasher... except using a toothbrush didn't occur to me.  I just didn't want to assume that bleach and vinegar could be used on LocknLock.

"Interestingly, I think the LocknLock containers actually retain too much moisture for some bread products; I've definitely experienced items that got too squishy or damp even when I made sure they weren't touching each other in the container. After transferring them to LocknLock, I still try to use all bread products by the "best by" date on the package or as soon as possible for homemade breads. The containers help them stay as fresh as possible and protect them from damage better than bags."

I had done a lot of experimenting with fresh baked bread.  Yes, I too, found that bread lasts a little longer in LocknLock than using the recommended paper bag.  So far for myself, I found that wrapping the loaf in plastic wrap helps.  Immediately after the first slice has been cut, I cover that end tightly with one long piece of plastic wrap that I use to continue wrapping a large remainder of the bread.   I leave the uncut end uncovered.  I place it in the LocknLock bread container... but only snap the long ends shut.   I do not close all 4 tabs.  I allow that little bit of extra air.   Other than freezing the bread, this is what I have found works best vs.  hard bread left in a paper bag.   Sometimes I will also cut a very thin slice of throwaway bread just off the cut end, when I begin to slice the loaf again.   

Unfortunately, this one time I forgot I left fresh baked bread in my LocknLock.  Though, I did expect black mold in my container, vs. the "fuzzy" mold that grew on the bread.   If you try this method, or find a better method, please let me know how it worked for you. Trying to hold on to any bit of freshness is challenging!

Marp... I, too, use paper towels to absorb moisture for fruits and vegetables.  I never tried placing bread in the refrigerator, because I had read several articles not recommending it.   Maybe I shall try it.

@rockyrose1  I'd throw it out. The piece isn't expensive. I wouldn't buy a duplicate for the same purpose for bread. I'd find something different.

I can relate to having a science experiment in my lock n lock. 1 of my printed seasonal bowls was pushed back and hidden for about 3 months.  I was afraid to try bleach, but I did do the white vnegar after cleaning it with hot dawn soapy water. Worked like a charm and saved the bowl.
