Review on Kitchen Scrub Sponges by Scrub-it - Non-Scratch Microfiber Sponge with Heavy Duty Scouring Power - Effortless Cleaning of Dishes, Pots, and Pans - 6 Pack, Small Sized by Brandon Wynen

I've had them for about a month now and they're great. I've only used one so far, but it's already had its first run in the washer/dryer. It has held up great. I love that there's a soft side for delicate dishes (nonstick) and a cleaning side for tough tasks (husbands who don't rinse out the cereal bowl 😩). Before that I changed the sponge on the first of every month. Haven't noticed a bad smell from this sponge yet, but I washed it on June 1st. There are small pieces of metal on the working side, so be careful with non-stick pans. It's great for cleaning the sink and mopping up water on the countertops!
