You don't even need to heat the plastic for the sauce to stain it. Fats want to bond with plastics, making plastics harder to clean + tomato sauce is awesome at staining. Heating might make it worse, but it's not necessary.

Yep. If it stains that means it's porous and is likely leeching plastics or plasticizers.

You can soak it in industrial strength bleach, but that red tint is never coming out

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.

Have you ever seen one of your plastic containers change color, because you stored tomato sauce?

You won’t be surprised that the same also happens the other way around, as your tomato sauce absorbs microplastic and contained toxins.

Plastics contain dangerous chemicals like Nickel, Antimony, or Ethylbenzene. They cause severe health problems from skin irritation to cancer.

Don’t microwave tomato sauce. Problem solved.

[–] XTornado@lemmy.ml 1 points 1 year ago

Not microwave plastic containers in general.

Tomato sauce does not just stain plastic, it tattoos plastic.
