Hose it off really good (if water is available) - if not blow it really, really good w/ a lawn blower.
I like to use Cheap ROOTBEER (the 3 liter bottles of "Store Brand" for about a buck a bottle) -- I use a 1/16th inch drill bit, and drill 2 holes in the lid -- Hold my finger over the holes, and SHAKE UP the bottles and Spray the surface (A Hudson sprayer works better, but remember to RINSE it out - cause it'll get sticky)
CHEAP Wal-Mart SPF 15 always worked decent (I have spf 30 in my box of tire sauces that ALWAYS goes to the track w/ me)
Make sure the tires have a clean/fresh cut on them if possible (Glazed tires suck)
