I buy foam sponges in packs, but not for washing dishes: I use them for other household purposes

I always have a supply of foam sponges, and I use them not only for washing dishes.

Fridge

Foam rubber absorbs moisture well, so I put it in those compartments of the refrigerator where excess moisture will be a hindrance, for example, on shelves with vegetables and fruits. The box is dry and vegetables last longer.
