Bill:
No, fish oil is not among the offending residues; mancozeb is
probably the worst I have. So you think an electric
2000psi, 1.4gpm rig, with a nearby fast hot water heater would do the
job? Or maybe even with cold water?
I like your suggestion on use of spray oil. It might work as well
against mancozeb.
Thanks.

Hot water makes a lot of difference.
But now if you’re using fish oil everything changes, that stuff is
harder to get off than most paint.
What I finally figured out to do with fish oil was to paint the
entire sprayer and tractors with spray oil before fishing season
started.
After the season was over the spray oil washed off easily with the
pressure washer and soap taking the fish oil with it.

Subject: [apple-crop] pressure washers
Northern Tool and Equipment lists pressure washers from under
$200
to several thousand dollars.
Would anyone care to advise on needed pressure, gallons per minute,
and hot versus cold water, or other
considerations in choosing a system to clean exterior surfaces on air-
blast sprayer and tractor after each
day's orchard spraying?
I am looking for an easier/better way to replace garden hose and
brush.
