Household Helps: Clogged Sink Recipe

I have been dealing with a kitchen sink that just gets slower and slower. There is a clog somewhere I am sure but I hate dumping all that toxic stuff, like Liquid Plumber and Draino, down the sink. I have just been dealing with it hoping, wishful thinking pershaps, that it will somehow heal itself. But the other day I was browsing around on Pinterest and came across a recipe for clogged sinks using baking soda and vinegar. Here's the link. Clogged Sink Recipe

I tried this today and the results were less than great but still hopeful. I dumped one cup of baking soda down the drain, followed by a little more than 1/4 cup of vinegar and then put in the stopper. I waited 30 minutes and then flushed with hot water. Well, the sink just filled up with water. I was a little disappointed but then, I heard gurgles and glups and then the sink suddenly drained. Yes! it works...I thought. I continued to flush with hot water for several minutes as per the recipe then I washed a sink of dishes.

However, this time when I pulled the plug, the sink didn't drain...it bubbled and gurgled, and it did drain a little faster than before but it was still definately clogged. So, I repeated the treatment. Again, when I pulled the plug there was nothing and then a sudden glub and out went the water. So, it is better but not great. I plan on repeating the recipe several more times to see if I can, enventually, clear the clog without having to resort to Draino or a plumber. Has anyone else had success with this method?
