Eli5: Why is tomato-sauce so good at coloring plastic red in your dishwasher, unlike raspberries or strawberries for example?

764 views

We like tomato sauce, but one must be careful with what to put into the dishwasher, to not have plastic bowls, storage boxes or other things dyed red…Why is tomato sauce this potent in coloring plastic. It’s like it’s in the fabric of the plastic itself after it comes out of the dishwasher…why not the same effect with strawberries or raspberries? And is there a way to prevent this?

Edit: Wow, this got some momentum…I see a lot of people like tomato sauces. Thanks for the awards as well!

Hello to anyone coming from /r/all or from the front page.

Just as a reminder, this is **Explain Like I’m Five** and there are a couple of important rules to remember:

1. Every question here should be considered as having an invisible “[Serious]” tag on it. Joke comments are not permitted as direct responses to OP’s question.

2. All direct comments should be an attempt to explain the phenomenon that OP has written about. In particular, ideas for how to avoid the issue, or anecdotes about how you have managed to stop this happening (or seen it happening to) yourself, are not permitted.

Thanks!
