A good habit would be to replace kitchen sponges 2 times a month, even if they appear intact. It is good not to use the same sponge to clean dishes and pots, and then also wash countertops, or cutting boards and other surfaces, this to avoid possible contamination: bacteria pass from one surface to another. After each use it is necessary to clean well sponges and dishcloths with warm water and soap, then making them dry well so that there is no mold. It may be the right solution to have a washing cycle done in the dishwasher.
