I used a bleach water mix to spray the inlet and the RV park hose bib.
You need to make it fresh often though because it deteriorates pretty fast even though it still smells like bleach. The following is an email from Clorox.
"How long does diluted and undiluted 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.
CODE PLANT YEAR DATE
MD21002 MD2 1= 2001 002nd day of year
A90288 A9 0= 2000 288th day of year
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."
