"Driving in the rain does NOT clean the undercarriage of your car. It has the opposite effect."
Water splashes up. My experience with water in the lower O2 sensor connections.
"Rain does NOT wash greases and oils off of your car."
It does. Why do you think, it is recommended to use waterproof grease on the undercarriage?
"I accidentally spilled a little transmission fluid on my driveway a few weeks ago when I changed the wifes alternator, and even after 5 inches of rain (no kidding - wet spring here in MA) there is still tranny fluid on the driveway."
Just because you see tranny fluid on the driveway does not mean the contaminants did not flow into the ditch or stormwater inlet after it rained.
" The dishsoap in and of itself is not a big problem, but the contaminents that it removes goes right down the sewer and into the local water supply. We've already covered that."
Based on this, are you saying that nobody should wash their cars in their driveways?
I am done with this thread. I am not wasting anymore bandwidth/time as it is obvious that you will only accept your own reasons.
