Have a stopped up drain? Clear the sink drain by dropping
three Alka Seltzer tablets down the drain followed by a cup
of Heinz White Vinegar. Wait a few minutes, then run the hot water.
This works great on most cloggs and saves money since these are
things you have handy around the house.

This works well! You can also use baking soda in a pinch. The other thing to have around the house is a sink plunger. They look like toilet plungers but are smaller. With a combination of baking soda, vinegar and a plunger you can clear most sink drains. The key is getting a good suction and really pulling up.

P.S. I used to work for Roto-Rooter and this was the owner's tip to me.
