Basically one f the mechanics mentioned that the Sprayer was connected (as its [the lever gun thingy] usually kept away in a safe place) and I also had cycled in and they where complaining the bike was looking a mess..so they showed me how to hook it up and turn on etc..!
Its a bigtime proper clean a BIG WAGON jobby so its ultra powerfull. And as I dont have much time to throw into clean every part for as I usually
had then this is quite ok. As I work in a mechanical workshop environement - a bit of spray on the chain: no worries !
One thing i did notice was this: one of the jobs IF NOT
the irritating job, to clean, is the chain and the chainring gunk, not that theirs much on it anyway but when it starts to build up then its a bugger to remove = not with a jet wash !!!!!!!!!!
And they are exciting to use, very !
