Re: [Killietalk] Bleach barrel question

["Stan Perkins" <stanperkins at academicplanet_com>]

Scott,

Two questions:
    1. Do you wash all organic material from the tanks before soaking them
in the bleach solution? Any remaining organic material will increase the
necessary contact time with the disenfectant.
    2. How long do you leave the objects in contact with the bleach
solution? 15 minutes is considered to be the minimum time for clean
surfaces. To save time and money, it is not necssary to use the sodium
thiosulphate. Simply rinse with running water and allow to dry overnight. It
only takes about twentyfour hours for chlorine to dissipate. How long do you
keep the chlorine in the dipping barrel?  It will be necessary to check the
concentration before each use if you do not replace it each time. Also a
build up of organic material in the dip tank can have an adverse effect on
the sanitizing ability of the bleach.
