take it to a car wash, spray it with the degrease sh*t, then use the pressure washer on the engine to get it clean. just watch out for the graphics, unless you want them gone then use the pressure washer to rip them off.
but after you clean it, oil the chain, grease all the zerk also, you can spray wd40 on everything (but the brake pads and rotors, if you have drums, then no worries)
but spray the bolts and nuts, and anything that when it rust will cause problems.
