I’ve found making a paste using bicarbonate soda, a capful of ‘the pink stuff’ non bio & capful washing up liquid really helps. I use a toothbrush (dedicated use purely for this job) to scrub onto it, leave it on for 10 mins and wash as normal and it gets all out x
@Marta amazing thank you! Also the amount of jumpers I have thrown recently when she’s had tomato pasta is ridiculous
