Thanks, guys. I won't say how long it has been since my lines were changed, but they are waaaaaay over due. The cutter is the way I will go, because like Challenger I also plugged a couple of nozzles trying to use a chop saw. Even after a good cleaning with a bore brush and solvent, something stayed behind.
My problem came from a corroded fitting, not the hose or when the hose was made. Fittings and hose need to replaced after some time. The white stuff stuck in your nozzle is fitting not hose.
I tried a shear years ago to cut hose, like said above it has to be really sharp, if not then your better off with a chop saw IMO.
