an easy way to disinfect hard, non-porous surfaces with a product you likely have at home is to combine 1/3 cup of regular chlorine bleach (sodium hypochlorite) bleach per gallon of water. (Clorox recommends using 1/2 cup bleach per gallon of water.) For small batches, use 4 teaspoons of regular chlorine bleach and 1 quart of water.
To use: Wearing gloves, dip a cloth into the mixture, wipe the surface, allowing the solution to contact the surface for five minutes and air dry. Rinse all surfaces, including food contact surfaces, like countertops and high chair trays, with warm water and air dry after disinfecting. Be careful not to splash the bleach solution on your clothes or in your eyes and use it sparingly on stainless steel sinks and surfaces. It's also important to note that the bleach and water solution needs to be made fresh each day you use it.
Hope it helps
