I use little cups for a variety of mineral & grit mixtures for my birds. Other than if they get poop in them I don't change them out; just refill if they get emptyish. The packages say something about changing them out & filling with fresh. I can't imagine minerals & grits would get "un-Fresh". What do you think?

If I see poop in the pot's I tip them over onto their cage floor , clean the pot and refill
If I have a breeding pair rear a clutch and fledge them to weaning I would also tip out the seed/grit pot's and clean them before use again with this pair .
Grit is such a minor expence and very important for your bird's digestion it's well worth having a supply there for your bird's .

I agree, unless the birds have pooped in their mineral cup, I often just top it off.

I do not use grit since it can cause impaction and the birds dehull thir seeds but I do a powdered oyster shell, finely grated mineral block and grated cuttle bone....if it gets poop in it is cleaned out and changed. If not dirty, I stir it up a bit.

I just add a pinch of mineral grit and a pinch of crushed oyster shell to each of the food dishes every day.
