The water is artesian.
This means that it is pumped out of the ground and, by the way, poorly filtered. Because of this, the car needs to be wiped immediately after washing. Otherwise, there will be divorces. And, of course, suspensions in water - the paintwork may be scratched.
Half of the functions in the devices are no longer working. Only foam, water and osmosis remained.
BUT:
Even if you just choose water, first it comes with foam, that is, you lose time and money, since you have to drive it all until just water goes.
In general, not ice.
