If you can go grab a cleaner set from a pick n pull that would probably be the easiest way.....I can tell you first had, that wvo tar cannot be removed easily.....the best solution as said, is heat or steam....I had a hell of a time getting it out of my fuel lines, I hooked up a handheld steamer and let it blow the lines out....took for ever, all the rest of the stuff I tossed and bought used that didn't see any wvo.....another option, is to build a camp fire and toss them in it for awhile....
