I would argue it’s also because most plastic isn’t actually very smooth and these oils get caught in the “pores.” It’s much harder to remove spaghetti stains from tupperware than from glass.
It’s an organic compound present in tomatoes called carotine that is liposoluble but hydrophobic so the normal water and dish soap rolls right over it. In order to get rid of it pour a good amount of oil and dish soap into the Tupperware and scrub all over with a paper towel, rinse and behold the magic
The tomato sauce has lycopene (sp? ) in it, which is a hydrophobic molecule, making it very difficult to just wash off. You can take a stick of butter on rub it all over the inside of the container, then put a paper towel in and fill it about half the way with water. Then put the lid back on and shake the shit out it. You should get it pretty cleaned off that way.
Can anyone explain why this happens? Bonus points if you can tell me how to remove it.
Oil/grease + tomato. Dawn.

Glass containers master race.

This was exactly the answer I was hoping for. Thank you 😊
It’s facepaint, and it comes off with soap and water.

Explanation of cause; basically, a part of the sauce sticks to the plastic instead of water because like attracts like.

Thanks for the links, looks like it’s time to utilize those last days of sunshine and apply the «hands off» method 😄
I’ve been told to leave them out in direct sunlight, haven’t tried yet tho.
