I read about this technique, then altered it, as I do most DIY projects, to suit my own needs. I can't believe how well it works, how cheap it is and how fast a solution to a slow draining sink!
To start with, I've had a slowwwww draining sink for .... oh, 6 months or so. Look, plumbing is not my forte' and I couldn't stand the thought of PAYING someone to unclog my kitchen sink. So I let it sit. And sit. And sit. Of course, the longer you try to use it, the more clogged it gets. After a period of time, it becomes an agitation and downright nuisance.
So I read the article, committed it to memory, and this morning after doing a major sink load of dishes and watching the dirty water just sit there eyeing me; I decided to try the method I read about.
The original "recipe" called for seltzer water or some such thing that I never have on hand and wouldn't think of picking up to unclog my sink so I substituted my old stand by: baking soda in vinegar. Now if you don't know: white vinegar and baking soda when mixed makes a volcanic reaction of epic proportion depending on quantities used.
It's always best to mix the concoction in a large container in case it does erupt. And yes, I knew that before I tried mixing 2 tbsp of B Soda in 3/4 C of vinegar and having it promptly spew foaming, bubbling white liquid over the side of the measuring cup and all over my counter top.
I digress. As usual.
Anyway...... put 1-2 quarts of water on to boil.
Once water is boiling, mix 2 tbsp baking soda in 3/4 c of white vinegar in another container. Promptly pour this mixture directly in the drain to break up any clogs. After the fizzing stops, pour the boiling water directly into the drain. Pour it, don't dribble it in. Use the force of the boiling water in quantity which will further dissolve, and sweep away, the clog.
I've been running my water over and over just to watch it swirl down the drain. Yes, small things sometimes entertain the most but look at this picture...isn't it a thing of beauty? :-)
