Chlorine Bleach and Sanitation
Have stated this before and it is worht repeating, chlorine bleach is not the best method of sanitising if one does not know certian things.
For instance high levels of organic matter/germs will deactivate the germ killing power of LCB. This is why directions state for disenfecting one must clean a surface BEFORE, using a bleach solution. Same applies to laundry, where commercial laundries will use a ratio of soiled laundry to bleach, adjusting for amount of soils. Even better bleach is added in a separate cycle after the wash water is drained so much of the organic matter is already washed away.
Water treatment plants constantly monitor conditions and will adjust chlorine content accordingly, which is why after a heavy rain, low water conditions, etc, one usually can smell tap water mile away. This means a higher than normal presence of bacteria have been detected and the chlorine bleach level has been increased to deal with the potential health threat. Some areas the water is so bad all the time, tap water always smells like "wash water".
There is also the fact that chlorine bleaches vary in their strength. Commercial laundries have dry versions of chlorine bleach that will blast away most anything. Such bleaches are used to "reclaim" badly soiled/stained linens/items that are going to the rag bin anyway, so if they are damaged by the high level of bleaching, it is no big deal.
Anyone who gets their hands on commercial chlorine bleach, should read the directions carefully regarding dilution ratios and usage. You may end up with white laundry, but it will be full of holes and in tatters.
