IMPORTANT BLEACH INFORMATION
How long ago was your liquid bleach or bleach product made? This is an
important question because liquid chlorine bleach loses its
effectiveness as a disinfectant at a surprisingly rapid rate. Unsold
bleach products can set on warehouse and store shelves for months before
they are even available for purchase by the consumer.
The following information was sourced to a major "name brand" bleach
manufacturer. It states that if you need full disinfectant effectiveness
from your liquid bleach, you'll need to replace it with newly
manufactured bleach at least every 3 months. And mixed water/bleach
disinfectant solutions need to be replaced after only 24 hours!
Bleach proponents should read the following information and
consider implementing an altogether new and more consistently
reliable disinfectant protocol. How many people will be trying
to protect their loved ones against urgent threats with OLD
bleach (i.e. an ineffective mixture of salt and water)?

How long does diluted bleach last?
For the answer to this question, see the
clorox@casupport.com email to
the Director of WCMC EHS dated February 6, 2003:
Thank you for asking about the shelf life of Ultra regular CLOROX liquid
bleach.
When bleach and water are mixed together to create a cleaning or
disinfecting solution, the solution is only good for 24 hours.
The temperature of the water does not affect the cleaning or
disinfecting abilities of the solution. After the 24 hours, the
solution begins to lose needed disinfecting properties. Therefore, it is
recommended that for disinfecting purposes, the solution is made fresh
daily.
Our bottles do not have an expiration date, however, they do have a
production date. Once you understand how to read the production date,
you can decipher the shelf life of the bottle. Please look below for a
chart explaining our production codes.

We recommend storing our bleach at room temperatures. It can be
stored for about 6 months at temperatures between 50 and 70 degrees
Fahrenheit. After this time, bleach will be begin to degrade at a rate
of 20% each year until totally
degraded to salt and water. Storing at temperatures much higher
than 70 degrees Fahrenheit could cause the bleach to lose its
effectiveness and degrade more rapidly. However, if you require 6%
sodium hypochlorite, you should
change your supply every 3 months.
I hope this information is helpful. Again, thank you for giving me this
opportunity to discuss our product.
Sincerely,
Mary Brylinski Product Specialist
