Since it is cold, we are getting to a point with our new home construction that we feel the need to get the dust, pitch, bird droppings, and fingerprints off our smooth planed doug fir frame. It was previously finished with a citrus base finish (Landark), but but since that time, the frame has seen a little rain, avian visitors who had eaten some red berries, and some dust and hand prints from someone's black glove before it was fully enclosed. What is the best way to clean the timbers? We have waited till now when it is below freezing to scrape the pitch, but it is turning into a huge elbow grease issue. There must be a better way...or product one of you experts might recommend.

What say you? Thanks in advance-Patty
