I had heard this from our lab folks also, but when I looked in the Center
for Disease Control's protocols for handling Mycobacteria, 10% household
bleach was the recommended disinfectant. The high concentration is
important. This 5000 ppm solution is much more potent than the 50 ppm I
normally use to sterilize tanks. I have never tried quaternary ammonium
compounds on equipment. Have you done so safely? The products I have used
tend to be quite soapy.
