I was using my Stihl ms290 (Farmboss in sig.) to cut a stump as close to ground level as I could....this is my first attempt...ever. Anyhow, the center of the stump (Ash) had a center that was rotted and filled with dirt (found out the hard way)....dulled the chain fast.....I then got peed off and buried the bar and chain into a big root that I was planning to finish digging out and cut. Needless to say, my bar and chain are an absolute dirty mess. Now that I've calmed down, and gave myself a royal arse kickin'....whats the best way to clean her up ???...power wash ???....the head is fine
