Touchless Carwash a NO-NO ?
Any comments ?
The manual is probably being cautious because some touch-less car washes may use harsh chemicals, although many places probably use safe-for-paint cleaners.

It goes on to say to avoid touchless car wash that uses caustic spray. Best to ask the wash operator what chemicals they use.
I have an eight year old truck I put through this wash and the paint and trim are still in great shape.

i wouldnt worry too much about tunnel washing (touchless) and assuming rims wont get damaged. I wash my cars very often inside tunnel wash and nothing bad has happen......
They do use softened water which doesnt spot much. The dryer sucks ***** in most tunnel washes.
Touchless doesnt clean the car well at all. If you do a finger swipe after, you will see how dirty the car is.
Touch was (tunnels) will swirl up the cars indefinitely. The cloth/brushes will not scratch paint, but it is the sand and dirt stuck inside that will....

Given the ph that is severely alkaline -14- and thus just as corrosive as a serious acid with a low say 2 ph.Therefore the ideal cleaner for a car used on salted roads, given what qaz says is a serious shower in a mildly acid solution, that would neutralize the road salts. The car wash chemicals can't help if they are base. The ph of water is nominally 7. We are looking for a bath below 7 with surfactants.
Consider adding perhaps gallon of white vinegar, such as found at grocery stores, to your DuPont or other ph neutral car wash. This will make the washing solution mildly acid and tend to neutralize the corrosive effects of the outrageously base road salts.
If you have your own washing container and some ramps to Get access to the underside, consider this sort of washing solution.
Has anyone tested the ph of say RainX winter solution the orange stuff? Perhaps one could use this instead.
After all the crap is gone, sluice with fresh water.

the most ideal is to reduce the amount of salt with large volume of water??
