I know Hugh, I know......when I lived at home I once had the bright idea of using mums dishwasher to clean all my pots. As you can imagine, it got blocked up, the pipes got blocked up, I got told off, mum got cross, dad had to get the wrench out, so on and so on.
From now on I will clean them all thoroughly, but isn't it just the most boring job ever! :-\
