How and Why to Dilute Bleach for Cleaning Hard Surfaces
If you use undiluted bleach directly on surfaces the sodium hypochlorite active in bleach naturally breaks down. The residue you will see is salt.
We never recommend applying bleach full strength to anything. Bleach should always be diluted with water before use. It’s important to follow the label instructions to make sure the product is used safely and performs as promised.
If you’d like to disinfect hard, nonporous surfaces, allow the bleach solution to contact the surface for at least 10 minutes. Then, rinse and air dry.
