The steps of this instructable show you how to remove biological mysteries from your sink's drainage without using caustic chemicals that cost money, are bad to breathe, less fun and whose success as an unclogging strategy has a lot of uncertainty.
My bathroom sink is simple enough that the pipes and pop-up assembly do not require any special tools to take apart and put together. The only tool I employed besides my hands was an old tooth brush.
This job takes me about 15 minutes; less time than it takes to go to the store and back to buy those old chemicals.
I read that you can keep pipes from bioaccumulating by putting down 1/2 cup baking soda, then 2 cups very hot white vinegar, wait 1 minute, bubble bubble, then follow with 2 cups very hot water.
Step 1: Prepare for cascading water and biofilms
Take all your cleaners, electronics, Make magazines and paper supplies out from under the sink.
Install nice large plastic tub. I prefer a tub to a bucket so I can get my hands in there and so I can see the wonderful microbial masses that come sliding out.
Step 2: Detach and clean U-bend pipe
Step 3: Remove and clean tail piece
Slide tailpiece pipe from sink drain pipe. Yours may need to be unscrewed.
See culprit biofilm on inside of the pipe.
Push microbial communities out, screaming and crying, with your toothbrush.
Step 4: Clean sink drain pipe
The horrors that come out! Kind of thrilling, isn't it?
