I left my Escher in the kitchen yesterday after using it, then today I found it had been moved out of the kitchen and placed upside down. To my horror there was oil on the honing surface, it had been there anywhere between 10-20hrs .

My initial reaction was to wash it in hot soapy water, but some oil has been absorbed. I'm guessing its cooking oil.
Would you suggest lapping it to remove the oil or just use it the way it is? I swear my foreign hones seem to be cursed eh. First the Coticule and now my Escher........
