If you put the plates onthe ground and let your dogs lick them clean , this gets the majority of cleaning done. Just needs a drool wipe off with a paper towelette before being put back on the shelf.

I did do that with my dogs and oven / baking trays. Their raspy tongues easily stripped all the burnt-on bits from the tins / trays, making them much easier for me to wash.
Alpha Bitch was always first while the others waited their turn to further clean a largely clean tin.
It was interesting watching them work out that sometimes a paw was needed, or a convenient wall, or the corner of the kitchen to stop the tin walking whilst being cleansed.
