Bought an H55F for my BJ42. I won't be installing it until next year, but I'm trying to clean it up for storage. It's got 25 years of grease, dirt, and sand caked on it. Have any suggestings for getting it clean? My plan is to soak it down with Gunk engine degreaser and take it over to the DIY car wash and blast it off. Some of this crud is a half inch thick! Any better ideas?
