It is more efficient to buy cheap supermarket sponges and replace them more often, or do you find that more expensive options are worth the additional cost?
I primarily use small (3”x3”) microfibre towels for dishwashing - bought a pack of four a while ago ant the grocery store and am still using them. I can’t remember what I paid, but I don’t expect it was much more than $6 or $7 CAD.
I also have a sturdier microfibre scrubby that’s holding up less well, which I wouldn’t buy again. And then, of course, steel wool for the big-time elbow grease jobs.
