I err on the side of thoroughness, but I use so much more time & water than others I see. I think I’m doing a better job… does it matter?
I want to watch an in-depth video of the minimum required washing. If you know or are a science educator (microbiologist? Epidemiologist?), maybe you can help :D
periodically microwave the sponge, they are bacteria farms.
Replace with cotton cloths, sponges are also micro plastic farms, and the cotton cloths can be boiled/washed on high and reused.
