Just caught DH putting the kitchen-bin lid in the dishwasher along with the usual plates and cutlery. AIBU to think this is gross?
(He says there are too many nooks and crannies to easily clean it himself - it's a Brabantia lid not one of those swing-top lids - and that the high temperature of the dishwasher kills all the germs.
I do actually wipe the lid (fairly!) regularly so it's not the first time it's been cleaned, by the way - this is just DH's attempt at a 'deep clean' :)
