Chux* for fridge, benches, bathroom, dusting, etc (I use a clean cloth for each task, wash the stash when I'm done).
Old t-shirts for polishing boots, wiping down outside furniture, wiping balcony rails (sometimes washed, sometimes tossed, depending on the task).
Paper towel for bathroom mirror (two sheets of paper towel each week), polishing the stove elements, cleaning the BBQ.

I bought a roll when we got married six years ago. Still have half a roll, still reusing the same cloths.
