Dishwasher is never ever used. It's rubbish and just welds food onto plates. Yes yes, I know you're meant to rinse first but really, what's the point? You might as well then wash them by hand.
Anyway... AIBU in using it to store tinned stuff in? DH thinks I am but I fail to see the problem.
It'd make finding tins easier as I can pull out the rack rather than climbing my short arse onto the worktop to look in the cupboard
