Neaver heard of a pressure regulator, I assume?
I said in disaster recovery situations. After a flood or fire, for instance. Have you ever had a computer go through a fllood or a fire???
Several customers of mine were in the disaster cleanup business. They ROUTINLELY clead computers and electronics i this way.
I alwys recommend at least 4 inches off the floor. Again, you SELECTIVELY read. The "dishwasher" was used for cleanup after fire and flood damage.
One of the WORST culprits for screwing up electronis today is CIGARETTE SMOKE.
