There's this product called grab-a-rag... They are washcloth-sized washable microfiber cloths.

Comes in a large box (think maybe a box that new boots would come in) but it's exactly like a box of tissues - pull one out, the next emerges halfway.

Once I wash them, I don't reformulate this tissue box set up, I just throw them in the drawers, I use them for wipes, I wash the floor with them, I have some set aside for dishes. They are mind-bogglingly good for cleaning surfaces.

I give mitt-fulls away because they're so cheap, and people freak out about how great they are.
