There are some unfortunate moments in our lives where you try, but never feel like you can get yourself totally clean. Being sick, getting covered in chemicals or other gross materials, having food poisoning, you name it.
A dude is seeking that extra cleaning action so what better way to power wash your entire body than by stripping completely naked, laying on the hood of your car, and going through a car wash?
I'm sure the industrial strength chemical cleaners and the high-RPM brushes meant to get stubborn dirt off of sheets of metal and glass will surely be effective on human flesh and hair!
Not sure how many passes this dude will withstand but if he really wants to get every inch clean, he should be spreading them cheeks.
