Its not that hard

. Here's one that I did before, lemme tell ya how:
Start by letting engine cool
Tinfoil off alternator, electrical connections, etc
Spray metal and really dirty (brake fluid filler is one of these, as is oil filler) spots with Gunk foaming degreaser
Use APC (Purple Power) in a spray bottle on everything else
Agitate with a wheel brush or other semi-hard brush
Wait 3 minutes, then hose off with a hose and no nozzle, use your thumb to get the spray goin on rough spots
Spray with Poorboy's BnB (order) or, if you need to go OTC, Mother's Reflections tire care or Megs #40, cut 50:50 with water.
Start engine, allow to run for 15 minutes
Towel off to smooth out streaks, etc
AIO or cleaner wax on metal
Enjoy
