If the clog is really bad then at any home improvement store look for one that contains sulfuric acid. Usually the stuff is sold inside a plastic bag. Also get some disposable pie tins (to cover the drain), gloves, and a mask as the stuff stinks, but it really works. I once used it in a shower drain in my condo and never once had a backed up drain for the entire two years I continued to live there.
