Viola: The Right Tool for the Job

After a tip from a fellow Instagrammer, I picked up a Lisle Parts Brush, and was finally made some headway in cleaning the spare S90 engine.  First, I just used some dishwashing soap to get the major grime off.  Some of it was caked on so thick that I had to scrape it with a screwdriver, but the brush actually cleaned where no brush was able to before.

After the soap, I was still left with a greasy residue.  So I switched to WD40 and the parts brush, which again worked wonders.
