In a whole lot of the western US there are environmental regulations concerning waste water runoff that make daily washing prohibitively expensive.
Around here you have to contain all runoff and either test it to prove it is “clean” enough to discharge into the storm drain or filter it until it is clean enough to discharge or have it hauled away as hazardous waste.
That, and in the southeast US anyway, you’re living in a desert.
Water is one thing that government at all levels browbeats you to conserve – and that’s particularly true of businesses.
If you’re really concerned about clean equipment (or facilities, for that matter) I’ll tell you that locally we have several vendors that can come on the premises and do the car washing a lot quicker and a lot cheaper than some Teamster carwasher can.
Same with porters, matter of fact.
So how’s about we farm out all the carwash and porter stuff in the interest of you having a spiffy looking ride?
Turns out that having a clean car wasn’t all THAT important to you, was it?
