I just remembered - one of the tips I heard years ago to help prevent staining is to use some non stick spray in the Tupperware before putting the sauce in. Because the plastic and fats hang onto each other, coating the plastic with a “clear” fat helps create a barrier to reduce staining.
I can’t recall having tried it. Somewhere along the line I gave up on using reusable plastic containers.
You can soak it in industrial strength bleach, but that red tint is never coming out
