I will start with the outside;
-Soak tires/wheels/wheels-wells , mirrors & front end with a Multi-Purpose Spray (Spray-Nine from Canadian Tire, or Totally Awesome from Dollar-Tree)
-If your bugs are SUPER-THICK on the front, a Dryer Sheet is your friend.
Two-Bucket System with a Megauirs Carnauba Wash/Wax and a soft wash mit. Go over the entire vehicle.
-Will use a seperate cloth or brush for wheels (brush for wheel wells if need be)
Rinse from top-down.
I use a Chamois (not the fabric ones) to completely dry the vehicle (If I am real serious I will use an air compressor to blow dry the tires/wheels and any crevaces I cant get to)
-If its the first wax of the season I will use Meguires Clay Bar kit and do the entire exterior..
I love using Megauires Carnuaba Wax with a Mothers Power Ball on a Cordless Drill: this works great, its fast, and easy to remove the haze*
Use a micro-fiber and wipe down all your door-jams, trunk & hood jams.
Clean exterior windows with invisible glass after wax. (Tire shine after vehicle is dried and before you wax, so u can get all the over-spray off)
Start with the wipe-down because you will get smeara or over spray onto your glass (can use air compressor and blow out your cracks/crevices)
-after your wipe-down (micro-fiber & multi-purpose spray) and can follow up with a Mothers Protectant.
-Clean windows with white paper towel (not cheap brown stuff) and Invisible glass; safe for window tint*
*Vacuum entire car (vacuuming front: put seats all the way back / vacuuming rear put seats all the way forwards)
This is a pretty thorough clean, you can also vacuum mats before you wash the car, soak them with shampoo xtract or Multi-purpose... Let stand, them scrub, and can rinse them out with pressure-washer/hose. Use wet-vac to suck out the water and or air compressor; the sun will also be your friend...
hope this can help some. whatever you do, drop a rag in dirt/gravel etc. DO NOT bring in contact with your paint. get a new one
