Generally storage boxes (I’m assuming we’re talking about those) are made from thermosetting plastics that should not deform under heat. Don’t use boiling water, just hot from the tap and it should be okay. Unless you want to get extra scientific and check the plastic composition.
Ah, I assumed ‘totes’ refered to tote bags. Should have read your descriptions more carefully.
If you’ve scrubbed with dawn, perhaps fill it hot water and dawn AND leave for 12 hours or so.
concerns about deformation on that front though. Hmmm.
