Best Drain Cleaner

After trying different drain cleaners over about a period of a month with no results.  I read online about using baking soda and white vinegar. Having both on hand and out of frustration and not wanting to tear out the pipes underneath and clean that way.  It's  one of the best drain cleaners I have ever used.  Just pored some of each in and a little plunging and water was running smoothly through the pipes again.  Best of all no fumes.  :-)
