Hit It With a Snake

While professional plumbing companies will have much more impressive equipment than a store-bought plastic snake, it's not always necessary to bring in the 'big guns'.  Plastic snakes from your local hardware store can be highly effective in dislodging and removing tough clogs.  There only real draw back is their length.  If your clog is too far down the line, these cheaper snakes may not be able to reach it.

Liquid Products

Liquid and gel products, like Drano, can dissolve and dislodge difficult clogs in many cases.  But they come with some risk.  These products use very powerful chemicals that are neither good for your pipes nor our environment.  Before using Drano or other similar products, try everything else you can first and keep in mind some of the risks of liquid drain cleaners.

A safe liquid drain cleaner you can use is of the all-natural variety.  Try mixing baking soda, lemon juice, and white vinegar together.  Pour it and let it sit a while, then try plunging again and see if that doesn't work.

Remove the P-Trap or Drain

Most sinks have a P-trap or other exposed pipes beneath them.  If easier techniques don't work to clear the clog, you can remove these pipes and dig it out.  Pro tip: be sure to have a bucket underneath as you detach them, as water and muck will likely go everywhere.

Try a Wet/Dry Vac

Using a wet/dry vac, you can try sucking the clog out.  You'll need to place the hose end at the entrance of the drain, then create as tight of a seal around it as possible.  If the sink has two drains, be sure to seal up the second drain entrance with a rubber stopper.  Turn your vacuum on high and suck that sucker out!
