As above. Wash/wipe once heated every few hours to remove the oil thats got to the surface. Basically slowly sweating it out, and taking away any oil immediately that has got to the surface, all ready for more to sweat.
Try and rush the process and the wood will "die" and dry. Its all about keeping the wood fibres "happy", breathing.
Might take a week. Basically the same process but opposite as when applying oil.
