Maybe I`m missing something with the ads logic? What exactly am I washing off my vehicle that wasn`t already, in the air, on the ground/road, or in the water? If using biodegradable soap, I`m not adding anything to the storm drains that wouldn`t have ended up in the storm drain, if I didn`t wash my vehicle?
Oh, what if I rinseless wash and only use about .75 gallon of water. Try using .75 a gallon in a tunnel wash. Take that NJ!
