Clean your kitchen counters every day after you prepare food. First, wash them with hot soapy water to get rid of any gunk and grime you can see. Then use a solution of 1/2 cup of bleach in 1 gallon of water (or whatever is recommended for your countertops) to sanitize them. Let them air dry. To help keep your counters germ-free, don't put your purse, laptop, phone, mail, or anything else on top of them.
