Sterilization By Chemicals

Chlorine bleach (5.25% sodium hypochlorite)

Bleach will kill many organisms immediately, but for full sterilization it should be allowed to react for 20 minutes.  It decomposes overtime when exposed to air, so fresh solutions should be made when needed.

To sterilize dilute 1/10 (one part bleach to ten parts water)

To kill tuberculosis bacteria 1/5 (one part bleach to five parts water)

To inactivate prions* 1/2.5  (one part bleach to 2.5 parts water)

WARNING: Bleach is toxic. It should be used in an open or ventilated area to protect your lungs and your eyes. It’s a chemical, handle it with care.  We don’t need bleach in our bloodstream, so protect your skin from absorbing it. Use gloves.

Hydrogen peroxide (3%)

 HP is simply a water molecule (H2O2) with one extra oxygen molecule.

It’s a sterilizing as well as disinfecting agent for kitchens, bathrooms, toothbrushes, etc. It can also be use in humidifiers.  It can be toxic if taken internally. Corrosive to metals if not diluted.

Full Strength  –  One cap full of HP in the mouth for 5-10 minutes a day to disinfect, whitens teeth, and eliminate bad breath.

50/50  (half HP/half water) – in a spray bottle could be use to clean, disinfect, and eliminate bad odors in kitchens, bathrooms, refrigerators, etc.

¼ cup of HP in aprox. 2 gal. water – This can be done in the sink or big bowl. To clean fruits and vegetables. Don’t rinse after, just dry with a paper towel.


Sterilized Dressings – Remember a dressing is sterile; a bandage is not. Soak clean cloth in a bleach solution (1/10) or hydrogen peroxide solution (50/50). Dry well. Wrap with foil or paper, label, and line up on a cookie sheet and place in oven at 300 degrees for 30 minutes. Remove from oven, let them cool and put them in zip lock bags. Place some in your car kit as well as in your first aid kit at home.

Bandages – Wash and bleach in your washer any white, soft color sheet or fabric that won’t bleed. Dry well.  Cut it in strips about 8 inches wide.

Fold in half length wise (4 in) and roll it up one at a time. Wrap individually with a brown bag (grocery bag), tape, label, and store it in a zip lock bag.

*Prions- Infectious agent composed of protein. Found as BSE or (mad cow disease) in cattle and as CJD (Creutzfeldt-jacok disease) in humans.  All prions affect the structure of the brain and neural tissue. It’s currently untreated and fatal.
