You can unclog your sink, shower or tub with 3 antacid tablets and 1 cup of vinegar. Works wonders!

To keep sink drains smelling good: once a month, sprinkle 1/4 cup baking soda into drain, follow with a cup of white vinegar. Let this bubble up and work for about 5 minutes. Next pour a cup of boiling water into drain Leave for another 5 minutes, then flush down with running water.

The way that I keep our drains clean is to pour a cupful of bleach down each one once a week, never had any kind of backup!
Cleaning drains with vinegar, baking soda and hot water. What's the recipe?
By ruthvalleygal (Guest Post)09/05/2007
I gave my suggestions for cleaning drains a few days ago, but maybe you missed them. I use about 1/4 cup baking soda, a cup of vinegar, and follow with a couple of cups of boiling water.Let set for a few minutes, then flush drains with cold water. There are no exact measurements, but this is approximately what I offered.
I would like to know if there is a homemade way to clear drains instead of having to buy Draino or another name-brand clog remover? I have some trouble with my bathroom sink not draining properly at times.

To safely clean drains, I pour baking soda into the drain followed by table salt. If the clog isn't bad, I just use cold water to flush it down. If the clog is bad, you will need to use boiling water. Since this will not harm pipes or the environment, you can use this weekly to keep drains from becoming clogged.

I also always recommend boiling water after any drain cleaning procedure to melt away any residual grease and soap. Cold water can harden grease further and will do little to flush stuck-on grease down since grease and water repel each other. Liquid grease, however, is carried down the drain by the water.
Vinegar, being acidic, does have a mild effect on grease, and the foaming will allow it to reach the sides of the pipe. Still, the effect is extremely weak and will do little to clean a drain. If vinegar was a good degreaser, you wouldn't want to eat it since our cells are coated with lipids (fats).
To prove my claims, simply do a little experiment. Coat something (i.e. spoon, Popsicle stick) with animal grease (i.e. bacon fat) and put some hair on it. Wait for the fat to solidify. Or you can simply use butter or margarine. Dip it into a baking soda/salt/water or baking soda/vinegar solution for about 30 seconds -1 min and see if the grease or hairs are gone. Usually, the answer is no. Now dip it into boiling water, and you'd see the grease melt and drip off.
Preventive maintenance is the key.
People with major problems might want to invest in bacterial enzymes to eat away the organic debris, i.e. grease, that coats your drain. This is a natural maintenance solution that sounds creepier than it really is. It involves no more than dumping a powder like substance down your drain with some warm water for activation. Google "drain enzymes" for more info. (02/08/2010)
I asked the guy for some preventative measures and he said, stay clear of chemicals. He said baking soda was only going to help with odors. He said we'll be good for a long time to come with what he did and we did get a 2 year guarantee. In the meantime I am going to be very careful about what goes down the drains and avoid any grease. By the way our house was new when we bought it, but we have lived here 23 years so it did take a very long time for there to be such a problem with the kitchen sink drain. (02/09/2010)
