Please settle an argument in my household.
We have just cooked 12 sausages in a grill pan.
Person A contends that the grill pan can go straight in the dishwasher and it will come clean.
Person B contends that it needs to be washed by hand because if it goes in the dishwasher the fat will clog it up and just be spread all over the other crockery.
Who is right, please?
