I'm late to the party, but I'm now on board the Touchless train.

I was sent about 2 liters of Touchless to sample last year, I tried it a few times and was not impressed. That's because I was diluting it too much in the foam cannon bottle and via the high flow rate of my pressure washer. I continued to use it in different dilutions and now think I have it dialed. Having said that, the bottle Touchless above is the recently superseded version, a more concentrated reformulation is available overseas and shouldn't be far off. That will mean recalculating the convoluted panel impact ratio.
I'll be completely honest in that I'm not using this soap on my own cars, they just don't need that sort of cleaning power. However, Touchless is too good not to have around when dealing with far dirtier cars than my own, it's cleaning ability is remarkable.
Also in that order was the new XL version of the Detail Factory Tire Brush.

Compared to the excellent original, the XL version offers four times the surface area, which should prove useful on larger side walls.
