Don't wash bottles in the dishwasher if there are the remains of tomato soup or passata sauce in a saucepan. Even if you think you've pre rinsed.
I have bottles with an orange tinge now.
Even the rubber colic ring from my Dr a Brown bottles have had a colour change.
Bloody hell.

Oops! I've come a cropper with plastic bowls and bibs too. Annoying, isn't it! Not sure anything can be done to get rid of the tinge, but they're perfectly good to use.
