Clogged Bathroom Sink

We purchased our home almost a year ago. The kitchen and bathroom are both very modern, but still beautiful and warm. I especially love my bathroom sink, as you can see, it's shaped like a bowl...The only glitch is that it has been "clogged" ever since. Meaning that I have to clean the darn thing 10 times a day or live with toothpaste and other gunky stuff staring at me every time I use the bathroom. It ruins the whole look and is not very hygienic. I did not want to use Drano or other potent chemicals. I have tried pretty much everything, hot water, bleach, vinegar, tweezers...to no avail.. Then I stumbled upon this homemade concoction and VOILA! I now have a perfectly white clean sink :-) I am happy woman

Recipe:

This is the most Eco friendly recipe I have found, and the least expensive as well.

-Mix together 1/2 cup of baking soda and 1/2 of table or coarse salt. (I used regular salt) -pour down in the sink, if you can, remove the drain stopper, mine just unscrews.
-Pour about 1 liter of boiling water down the sink.
-Wait 10 minutes and open the cold water tap for a few minutes, that should clear up everything.

***They recommend to do this once a month as maintenance***
