Wonderful research, great reporting; do you think they could spare a sentence or two concerning what to do about it?

Exactly what I was thinking. I went to the link just to get some practical information.
I periodically scrub out the drain area of the bathroom sink down as far as an old toothbrush will reach. I use a bleach based cleaner. I hope I am breaking up the biofilm and offing these disgusting molds, but who knows?
Every now and then I pour a pot of boiling water down my kitchen drains...figure it would melt guck that might be clinging to the side walls of the pipes..also use baking soda and vinegar. That bubbles up and cleans the drains also...
