[Accumulator]

I use an undercar wand for quickie rinses, works almost as well as my (currently inop) pressure washer did and it's *so* handy. I dunno how well it would work without my boosted water pressure though.

The steamer works well, but it's very slow going.

A few Qs for you pros, who have to handle neglected vehicles and a large volume of jobs:

-Besides the undercarriage spray, how do you get things *really* clean under there (in an enviro-conscious manner)? I have to spend a *LOT* of time with solvents, cleaners, natural-bristle brushes, and the steamer..not sure my aproach would work well in a commercial setting where time is money.

-What about the run-off? I trust my oil separator to do a satisfactory job (it's to-commercial-code for my area), but I do wonder about emulsified oily [crap] anyhow. Without the separator, and floor drains connected to a sanitary sewer, I'd be leery of the run-off...no way I'd want that stuff going down a storm drain.

-What about using solvent-soaked rags for really greasy stuff? How would you get rid of them once they're soiled? Doesn't seem like something you should just put in the trash/send to a landfill.
