Ever since we've been in this house (~11 years), the master bath sink slowly clogs every 4 months or so. The culprit is a slow build-up of this nasty slime, until the sink barely drains. Then I disconnect the stopper, remove the trap, and push the slime out with a stick and toilet paper. Clean everything up real nice, reassemble, and maybe put some Drain-O down the overflow. A few times I've tried putting some bleach down every week or so, but eventually the slime builds back, then I rinse and repeat. I've never experienced anything like this before, and it's the only sink in this house with the problem. Obviously there is some type of slime colony living in the drain, but I can't seem to kill it all off. Anyone ever encounter this? How can I solve it once and for all? I'm in Colorado if that matters. Maybe we have some weird regional slime. Thanks for your time.
