I don't usually recommend specific brands, but I don't know if there's a "generic" equivalent. You can get something called CitriSolv from Fisher Scientific or VWR (I think they both carry it), which is a citrus oil based solvent. More "eco-friendly" than xylene. We use it for clearing paraffin from histological sections, and it also works well on the lab benches for cleaning spilled paraffin. But, beware, any of these solvents will do a job on plastics too, so if you have any plastic parts in your equipment, you'll have to resort to old-fashioned scraping off of paraffin.
You can go to auto parts store and get brake cleaner. It is usually a combination of toluene, hexane, and xylene packed in a OH, convenient spray. It will pretty much dissolve anything that is organic, your http://www.eifzc.com/petroleum_jelly_and_paraffin_wax.html" [Broken] also.
