If your car is suffering from the rigors of pollution, dirt, mud or the occassional passing cowboy (tobacco juice), it's time to soap it on up. In the interest of helping you have the cleanest car possible while protecting the environment I give you my Top 10 Tips for washing your wheels.
1. Start by gathering the necessary supplies, including a bucket, soft sponge, chamois for drying and soap which should be made especially for washing cars. Dawnฎ may get grease out of your way, but it doesn't do much good for your paint.
2. Find a shady spot and park under it. I prefer washing my car on the grass because it sorta waters that part of the lawn, too. Note: If you do wash your car on the grass, leave it there until the water soaks in the ground or you will create muddy ruts when you drive off. It also helps if the car is in the shade long enough for the surface to cool off.
3. Yank your hose (snort) to your shady spot (double snort). Here's where you may diverge from my tips. I prefer not to use a spray nozzle, instead letting the water cascade off the surface like a mini waterfall. That reduces water-spotting and drying time when you're done. However, it also means either hopping over to the faucet to turn it off while you scrub or letting lots of wasted water dribble out while you work. That may be OK, if, like my lawn it really needs the water.
4. Hose down each part of your car before you start scrubbing. This loosens dirt and also helps cool you off if it's hot outside. Start with the roof, windshield and hood. Scrub them with lots of soap and water, then rinse. Where you go from there is your bidness, but I usually pick a side, work my way around to the rear and then hit the other side (sounds like a bad first date, doesn't it?).
5. Now it's time for the wheels. Because they are usually really nasty, I save them for last. This way the road grime doesn't make its way to your sponge while you are cleaning the paint think sandpaper and you'll know why. I have a little brush that I use to scrub the tires, and then I work my sponge into the wheel itself. This is also a good time to clean wheel wells, mud flaps or whatever else is down there (snort!).
6. Now that you are finished washing, it's time to dry. If you didn't use a spray nozzle while rinsing your job will be easier. Simply wet your chamois and carefully sop up the water. Once again, I usually start with the roof and let gravity help me get standing water off the car. Sometimes I follow up with a soft, 100 percent cotton terry rag. Not drying a car can leave little white spots on your paint (mineral deposits) that might eventually turn into car pox that can't be washed off. Don't ask me how I know!
7. As you're drying, open the hood, trunk/hatch and doors to wipe the door sills. If you have a car made recently it probably has "limosine-style" doors that are great insulators from muck and noise while you're driving, but it means dirt gets trapped on the door sills. Save your clothes by wiping them down every time. I don't always open the hood, but sometimes some nature (acorns, seedpods, slow-moving politicians) gets trapped in the corners of it.
8. Once the ground has dried sufficiently, I usually move my car to the driveway for a good sucking (of dirt, that is). If we've been on a road trip and the one we're going on late next week includes a sandy romp to the beach sometimes I have to use my shop vac. Usually, the household vac will do just fine, and has a good brush for sucking out the air vents or between the seats. If you are washing someone else's car, let your hands carefully clean out all the loose change (consider it a tip).
9. The rest is details and is a matter of preference. If your carpet is really gross, buy a nice canned cleaner and use a wet rag to get the dirt out. If you have a household carpet steamer, this can help greatly. For interior windows, I bought some ammonia-free cleaner that leaves my windows streak-free and smelling great. A vinyl/plastic protectant can give your dash and door panels a nice sheen, but I don't get the extra-shiny stuff. I try to keep our vehicles waxed (done about twice a year), using only pure wax like Meguiar'sฎ. That stuff also softens your hands while you do dishes.
Of course, there is one extremely helpful tip that, if you can find a willing person, will make the job that much better ...
