" Is thia literally just spraying rhe degreaser on there and spraying it off with a pressure washer or what? "

I never use pressure washers because they cause so much damage .

I use soft bristle brushes with this and other de greasers then a controllable garden hose nozzle to rinse everything off .

Be sure to rinse extremely well as any cleaner residue on alloy parts will cause corrosion quickly .

No way to do this sort of cleaning without you getting very dirty, that's the nature of the job .
