Tip: How to clean your kitchen sponge
Just put a few drops of dish detergent on it with some water and put in the microwave for 1 minute on high..cleans bacteria better than running through the dish washer unless you have a sanitize dial on your dishwasher.if you do put on top rack and run through cycle. Make sure there are no dishes blocking the sponge.

Only if your dishwasher heats the water hotter than it already is when it comes out of the water heater. Scalding hot from the water heater is more than hot enough to sanitize a sponge. Or - do it your way. I wasn't asking IF I could put a sponge in the dishwasher to clean it, I was telling you that I've been doing this since long before microwaves were affordable.

leave a dish of vinegar in your sink over night with the sponges in it, you can do the same with bath scrubbies and scrub brushes. Vinegar is a safe cleaner that kills bacteria. It also freshens your drain when you pour the left over vinegar down. Less chemicals for all. If you want the hot water effect, put your items in the sink or a bowl, then add the water you heat in your microwave or stovetop. When you heat many man made materials in the microwave, it releases fumes and chemicals from them.
