Im sorry..
I just need to giggle here.
You guys saying you cant live or clean without an extra 20° to 30° are missing something in your pie.
Like one more ounce of chem or a few mintutes more of dwell..
Or a brush.
All of which wont melt olefins, burn lawns and skin, eat up your hoses and valves or over tax your machine.
And yes, we run our BIG trucks at 200 to 220.
Anything more is giggleworthy.
