Angle of the cut

When washing fleets do you use a angled cut with a back&forth,up&down or sideways mo'sion? I use the back&forth with a slicing cut when washing fleets..

We wash a large meat packing fleet and my guys use the turbo tip up and down but be sure to use low pressure when you get near the decals.

A turbo tip??? You are a brave man. I have used them on Garbage trucks, but the ones I used them on had minimal decals. I was upstreaming soap through it as well.
As for technique, I usually use an up and down motion, mainly because the trucks are typically parked to close together for me to do it any other way.

I washed a hopper bottom one morning real early,I think it woke everybody in town up.Even at low psi the sound it made against metal would have woke up a dead person.It was a new toy but early in the morning isn't a good time to play around with a turbo on metal.

O...I could never should get the hang of the up&down way of cleaning

up down>> all around >>side ways>> in and out...............Oh..crap....... you are talking about washing........ sorry My bad !!
