The sponge is definitely carrying bacteria from dish one to dish two. But the soap + scrubbing is making the mechanical removal of food and bacteria much easier. Basically freeing it from adhesion to the surface of the dishes so that the final rinsing with water carries the bulk of it away and down the drain. I personally think sponges are gross and not good for cleaning things involved with eating. They harbor bacteria like it’s nobody’s business and you’re right to be questioning this. I’d recommend switching to a plastic bristled brush that you can fully rinse with before each dish or item that you wash.

Really good idea to keep your sponge/scourer dry between washing sessions, don't leave it in the sink to stay moist and help bacteria survive. I often nuke the sponge/scourer in the microwave. Add soap, some water, put in bowl or plate and nuke on high for 2 minutes. Also has the benefit of steaming up the inside of the microwave and makes the microwave easier to clean.

I rarely use a sponge but when I do I microwave a wet sponge for two minutes to kill bacteria. It’s extremely hot afterwards so be careful.

I use a plastic bristled brush too. Anytime I run the dishshwasher I'll put it in there to kill off additional bacteria. Otherwise it gets a thorough rinse and set upright in the counter drying rack. I don't think I will ever return to sponges.

Thanks for the answer, I’ll definitely be looking in to finding an alternative.
