Citrus cleaner is good, but as it's an acid, and not a base, It would seem to me that it could potentially damage the base more so than kerosine.
While kerosine is similar to diesel, it evaporates very fast when spread out. I don't believe it leaves an oily residue. I could be incorrect, however I have been using kerosine on my base for the past 4-5 years (before I bought cleaner) with pretty good success.
The horse hair brush is a good recommendation as well. The videos are great for begginers, as words sometimes just aren't enough!
Also, where are you riding at on Hood? I'm riding meadows myself.
