Have at it.
I bought my Rohn 45 as a used red/white painted broadcast antenna. I rented a
commercial power washer to blast off the paint and clean up the few rusted chip
spots prior to painting it with zinc/galvanize paint which was painted right
over bare metal, bare galvanized areas, and areas with paint still on them.
That was almost 20 years ago and the tower still looks great. The cold
galvanize is solid and not peeling.
Basically, the galvanize is impervious to pressure watching and would probably
need sandblasting to get it off.

Any harm in pressure washing galvanized tower?s, or steel bases, masts etc ?
I have bird crap and stuff on some portions of mine. Mine is just a small
electric
one... but its capable of ripping the paint off of wooden steps etc, if too
close
or wrong attachment wand used.
It would save a lot of time, but I don?t want to damage the galvanized
surface etc.
The idea was to use just enough pressure to clean it without damaging things.
I suppose I could use a soft nylon brush and soap and water too...then rinse.
later... Jim VE7RF
