How do I Clean a Stinky Drain?
How to clean out stinky drains and get rid of biofilm:
The sink drain in my downstairs bathroom was putting off a pretty nasty funk last week. After cleaning the whole bathroom from top to bottom there was still a musty, rotten odor.
My little guys use that sink to wash up some pretty remarkably disgusting stuff they find lying around outside, so it wasn’t such a big surprise. In desperation, I took the J trap off to see if there was a dead mouse or goldfish in there or something. The odor was apparently coming from this nasty biofilm buildup.
Biofilm forms when bacteria sticks to a surface in a wet environment. The bacteria excrete a slimy substance that is very difficult to eradicate. (Dental plaque is actually a biofilm!)
How to fix a smelly bathroom sink:
I poured some hot water down the drain, and then two scoops of ecogeek’s OxyBoost. Then I poured about a cup of very hot water on to get the powder into the trap and activated. It bubbled and steamed for about 20 minutes and then I poured another quart or so of very hot water down. Took the trap off again and, voila!
