:::::If it rains whilst your car is in the driveway(/at the kerbside), the same stuff potentially gets washed off. The fraction of particulates/contaminants that you can deliberately ''keep'' on your car until you go to a (''presumably'' particulate-filtering and safe-disposing?) car wash is minimal. Assuming it does filter, at all. The environment (and civil drainage infrastructure) cannot be considered that much better just because you take your practically clean car to the autowash occasionally just so that you could eat your dinner off of it. Perhaps a special exception when you've been off-road/driving through quarry tailings/whatever and are particularly caked with muddy grime/grimy mud, but not when dealing with the latest 'saharan sand' dustings/etc. There's scope for judgement, at least.

:::::I'd worry more about surfactant over-use, but looking at the "one size fits all" foam-fest of a typical carwash/jetwash soaping (and unsure how you'd filter that from water, without effort, the whole point being the (half-)hydrophillic nature of the substance) I'm sure that adds more water-treatment effort at the ultimate end of the drains from either the home, street or nearby carwash (which, given we don't have separated rainwater and wastewater drainage systems is already potentially taking away everything that was left to settle on the roads, oil and dirt and mud and leaves and everything else that gets washed/dumped down there). Local laws/situations aside, I'm more comfortable with home-carwashing than it seems some are. Without wasting resources on running a home jet-wash.

Am I the only one who actually tried to find out whether baleen really used to be used in car washes or not?
