What you will need
-(2) 2 Gal. Wash Buckets (Wal-Mart)
-Mother's Gold Car Wash or Meguiar's Gold Class Car Wash (Wal-Mart)
-2 Soft Cotton Chenille Wash Mitts (Wal-Mart)
-Waffle Weave Microfiber Towel (http://www.pakshak.com)
-Hose with a multi-nozzle pressure head
What to do
-Hose down your car from top to bottom with moderate pressure. Do not forget to hose down all inside your wheel wells and the underbody as well.
-Use a two bucket method (#1 bucket of water, #2 bucket with roughly 2-3 oz car wash and the rest of water). Begin with both mitts in the soapy water.
-Soap the car up with mitt #1 going from FRONT to BACK (the way the wind flows over the car) about 3-5 strokes, then flip the mitt and do another 3-5 strokes. Make sure you do 1 panel at a time.
-Throw the dirty mitt into bucket #1 (all water) and let it submerge
-Repeat the washing step with the second mitt, throw the mitt in bucket #1, then take the first mitt out, put in the soapy water and repeat the washing step.
-After everything is soaped up, let the water run free (no nozzle attachment on) to remove the soap. Letting the water run free allows it to flood the surface and it will sheet off, allowing it to be easier to dry.
-For DRYING, I only use Waffle Weave Microfiber towels. They are very soft and plush, and dry very nicely. With a folded WW MF, lightly drag the towel over the surface.
Notes
-Doing this 2 bucket/2 mitt method, you allow almost no dirt/contaminents to drag across the surface. The dirt/contaminents get trapped in the pores of the mitt.
-Sponges are terrible because they have very small pores. These pores trap the dirt, then build up as the sponge goes over the surface. Ultimatally causing it to act as a fine grit sand paper over your surface
-I would personally either buy an extra mitt, or use the mitt AFTER you do the entire car for the rims/wheel wells.
-When you wash these mitts, wash with other "car" towels on warm/reg. detergent and DO NOT dry by machine (just allow to hang dry). I like to wash the mitts after EVERY use, just to make sure all the crap is out of them.
-If you don't want to wait for your WW MF to get there, you CAN use 100% Cotton Terry Towels (Wal-Mart). I would only reccomend using brand new ones for your car and designate them for washing (so nothing else gets in them). I reccomend washing the towels before using (warm water w/ detergent wash and medium machine dry, NO FABRIC SOFTENER).
Any other questions, post them here. Hope you learned something new about washing
