DIY Waterless Car Wash Contest
There is one DIY activity whose simplicity and seeming thrift is not as good for the environment as is going with a commercial option, and that is washing your car. That is, if you use water.
Washing a car at home can use between 80 and 140 gallons of water, while a commercial car wash averages less than 45 gallons per car.
And where does that water go, comparatively? If you live in a city or town, water from washing the car in the driveway goes into the storm drain, with the detergent, car grime that can include oil and gas ending up unfiltered in lakes, streams, and rivers. Studies have found heavy metal contamination as one of major concerns with car washing, both by homeowners and commercially.
Water from a car wash by law needs to go through a sewer system and as a result is filtered before it is released back into the environment.
Phew, no feeling guilty about not spending Sunday afternoons washing the car in the driveway.
But wait, I guess we are not off the hook so easily, because even 45 gallons of water to wash one car seems like a waste of this precious resource, especially because that 45 gallons is becoming highly polluted. Besides, how many car washes do you know that use a “green” detergent? The story gets even worse if you choose the waxing option. And how much energy does it take to wash one car? Some in the industry are making strides in using sustainable energy, but such places are still hard to find.
Fun green fund-raisers: Note that high school car washing fund-raisers and such will be breaking the law if the water is not properly disposed of in sewer systems. For this reason sometimes schools hook up with local car washes to raise money. But there is a fun option available that has some cache to boot, and that is to have a “Green” Waterless Car Wash.
So let’s get back to the fun of DIY. How about washing your car at home using a waterless car wash? One recommended product is Eco Touch and another is Freedom Waterless Car Wash.
Even more fun, make your own waterless DIY formula. I’ve been playing around with some formulas for a few months and I think this one I am going to offer is pretty close, but there is still one pesky problem, and that is that if you don’t polish the car enough the detergent/soap might bubble when it rains.
Please put your creative formula hat on and let me know what you think would work as a stellar waterless car wash formula. Here’s mine:
Winging It Waterless Car Wash
½ to 1½ cup baking soda (non-abrasive cleanser)
½ teaspoon jojoba (liquid wax)
½ teaspoon liquid castile soap or vegetable-based green detergent
2 teaspoons water
Combine all the ingredients in a bowl and mix, adding more baking soda until the consistency is of frosting. With a clean cloth, rub the paste onto the car. Polish and rub until all the paste is gone.
Other ideas? Please share! Give us your DIY formula suggestion in a comment and I’ll try them all out and give you the one I think is the winner.

I use the local Greenmachine. The fine spray from the nozzle lets you wash a car using as little as 1/4 gallon of water (or waterless solution). www.greenmachine360.com

micheal, what you said may be true, but i use a damp to wet cloth first. i'm trying to minimize my work and not get soap involved. that would mean having to rinse the soap and then drying. i
only wash when it gets a little dirty, otherwise i spot clean. sometimes i take it to the do it yourself wash and use their wand - not so green.

Good idea, but won't this cause the abrasive dirt particles to eventually dull the surface of the clear-coat (over time will make paint look dull and washed out, until clear coat is gone, then paint will look flat/matte) without water to act as a solvent, lubricant, and carrier to assist with dislodging and removal? In traditional cleaners, the soap reduces the surface tension of the water (makes it "runnier", like hot vs. cold honey), disrupts the strength of oil-based bonds slightly, such that the water and dirt can be emulsified by other ingredients in the detergent, and further water can rinse the emulsion of dirt/detergent/water away.

i use two microfiber cloths, they are the best. one is fairly damp from a little water bucket and i go over a car area - if stubborn dirt, i use a little baking soda to clean. i then dry that area. as for the windows, i use water because glass cleaners have wax. i have an advantage over most people - i own a smart (5'x5'x8.8') car.

Let our almost-3-year-old toddler loose around our 2 Priuses and I guarantee that she polishes up those cars in no time! She's getting particularly proficient in wiping the sides of the cars with her butt, and her little hands and sleeves work well too.
