Some personal experience with Blue Juice in horn rotors gives me reason to
advise people not to use it on horns. A friend, who's horn I clean, left her
Blue Juice bottle accidently in her car trunk for quite a while. It went
through the PA winter and summer. When she found the bottle what was left of
it was dried up rubbery blue gunk. When I cleaned her horn out there was gunk
in the rotors which hadn't been there before she ever used blue juice. I know
someone will not be happy with me for giving any problems about it. I used to
help my husband with brake repairs and some other car work. Plus we lived on
one farm where our landlord had an old dump truck with 400,000 miles on it (no
kidding). He never changed the oil in it. Talk about gooey old black oil!
Still, old greese looks nothing like that blue juice did. I used blue juice a
couple times on trumpet when I still played it once in a while. Trumpet valves
are more controllable than enclosed
horn rotors. After seeing that my personal preferences are to stay away from
Blue Juice for horn rotors.
