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 with Natural Choices refillable BATHROOM cleaner, 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!)
Unfortunately, I was out of our Natural Choices OXY-Drain but, as always, I had my handy 20 pound container of OXY-Boost on hand.
How to fix a smelly bathroom sink:
I poured some hot water down the drain, and then two scoops of OXY-Boost. 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!
I’m told biofilm is actually extremely difficult to remove. Seemed pretty easy using this method with OXY-Boost oxygen bleach. OXY-Drain will have the same effect, but it also contains enzymes to break down food, grease and oil in the longer term.
