Not possible to have steam at those conditions. Steam has to be at
more than 1000 F to reach such pressures. If you pressurize steam to
3000 psi it will condense unless very hot. The liquid in question will
begin flash into steam as it leaves the sprayer tip. It might not be
properly called steam cleaning, but I admit that is a nitpick.

In my experience, steam cleaning uses just steam.

But wouldn't 700+ degrees have a detrimental effect on fiberglass?


You're darned tootin' it does! Those temperatures will soften it up. It'll
also cause any trapped moisture to boil out causing more holes and tiny
fractures into which sea water may ingress to cause further blisters later
on. This new 'drying out' method advocated by Skippy and a few other fools
in this group is just so destructive. Makes me wonder why ANYONE, even
morons, are stupid enough to believe it.
