replacements for my dobie scrubber

Non-abrasive scouring pads made of coconut or agave fiber are becoming more common. They look like Scotch-Brite pads, but are brown/beige instead of green/yellow. (Note that plastic lookalikes exist, so it's worth checking the label.)

microfiber dusting cloths

I find that a slightly damp cotton washcloth picks up dust pretty well. If you have lots of dust, it's easy enough to rinse, wring, and repeat.
