How to Properly Make
and Use Sanitizers & Disinfectants
SANITIZING FOOD CONTACT SURFACES
A solution of bleach and water should be used to sanitize all food
preparation and contact surfaces.
1 tablespoon of bleach per 1 gallon of water will give you a
50-200 ppm sanitizing solution.
This can be used to sanitize dishes, utensils, food preparation counters and tables.
* Make sure that you use only UNSCENTED bleach for food contact surfaces and that
you are using chemical test strips to check the sanitizer concentration. All spray bottles
must be clearly labeled with contents.*
DISINFECTING CHANGING TABLES, BATHROOMS, TOYS
All changing tables/diapering areas, bathrooms and toys must be disinfected after each
use. The following solution of bleach and water should be used on these surfaces:
1 tablespoon of bleach per 1 quart of water
¼ cup of bleach per 1 gallon of water
This will give you a 500-800 ppm disinfecting solution. Remake solution daily.
Soaking method for toys:
Wash and rinse toys to remove any visible dirt. Soak toys in a solution of
¾ cup of bleach per gallon of water for 5 minutes. Rinse toys and allow to fully air dry.
IN CASE OF ACCIDENTS AND ILLNESS
For all surfaces impacted by ill children (vomiting, diarrhea), a stronger solution of
bleach and water is required.
1/3 cup bleach per 1 gallon of water
2 tablespoons bleach per 1 quart water.
This will give you a 1000+ ppm disinfecting solution.
After cleaning the area with detergent, spray or wipe with surfaces with the disinfectant.
Make sure to allow surfaces to fully air dry.
