The death of an amplifier

I generally try to hose down my system with a pressure washer at least once a week. Should I stop doing that?

I hope this is not too far off the subject but I'm asking about solid state amps. I have currently sworn off tubes, but tomorrow's another day. Actually tomorrow is Sunday so I hope all of you will follow your relijus convictions and go to church.

Tom, are the things you mentioned preventable or can I take preemptive action? Will I be able to hear capacitors that are on the way out? The Aragon amp does not run real hot. It is warm to the touch but it is not in a rack. There is nothing immediately above or below it. It is about four inches above the floor with nothing above till the ceiling.
As far as the on/off switch, the only time I turn anything off is on the rare occasion when I move equipment around or when I am going away for a while. If there are things I can do to extend the life of these toys I would be interested. Thanks for your help.

Actually religion is run by people who couldn't find God in their limited perspective which was the reason Jesus was so unhappy with religion. To give 'will' the benefit of the doubt though, I guess one persons pasttime can be anothers pointless religion.
