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.

Me three!!! Pristine bottles now have a nasty orangey tinge from spag bol!! FML

I've done it too!
