First, clean your counters, sinks or utensils with soap and warm water. Rinse thoroughly.
Second, spray the rinsed surface with a sanitizer.
You can make an effective, inexpensive sanitizer with common household ingredients.
You can use 6% chlorine bleach. Check the active ingredient label.
You can use distilled white vinegar.
You can use hydrogen peroxide.
Add 1 teaspoon of chlorine bleach, or vinegar, or hydrogen peroxide to 1 quart water in a spray bottle. WARNING – never mix the vinegar and hydrogen peroxide together. This is toxic.
Spray the clean and rinsed kitchen surface and let air dry.
If you are in a hurry, dry with a clean paper towel. Throw the used paper towel away.
