Touchless does help in removing the dirt/film that would get left behind if just jetwashing the car without it, esp once that paint starts to dry as the paint looks clean when its wet.
Touchless is abit expensive for me at their usage ratios to get the correct PIR of 2% I have to use around 220ml of solution topped up to 1 litre so 4 uses per litre. What I did realise is that I was able to do a van and small car before it ran out so now I use around 110ml topped up to 500ml and its fine for a mid sized car.
I might see how a citrus/tfr as its cheeper and see how it fairs esp on some cars where they dont get cleaned for a very long time or stop using the touchless on cars that are already scratched to ****.

So I've switched, and I'm going to try out Stjarnagloss Glatt instead. 5L cost me £45. So I gain an extra litre, and save £30!
