How often should i microwave a sponge?

Question

to keep it sanitary?

Answer 1

I never heard of that.  You can do the same thing by soaking in hot soapy water for a few minutes or putting it in your dishwasher.

Answer 2

Once a day;  I do mine first thing in the morning.  Twice a day if you want to, but once a day is enough.

Answer 3

Once a day is good. I also store my sponge in the dishwasher. It gets cleaned every time the dishwasher is run.

Answer 4

if u have a dishwasher just put the sponge and your dish rangs in there to wash them
