Dwight's right, you don't need the spray. Apart from that, I would be
very wary of a "high pressure wash" -- high pressure anything can
damage tracks and plated holes by stressing them where components are
fitted.
If you do wash it, beware of any switches, relays, transformers, etc --
and *don't* dry it in an oven. You'll evaporate the water, leaving
behind any minerals (hardness in the water etc), some of which will be
hygroscopic and/or corrosive. Excessive heat can be a bad thing too.
It's better to give it a final rinse in water with a *small* amount of
wetting agent (so most of the water drains off), and blow away as much
as possible with *low-pressure* compressed air. Or rinse in iso-propyl
alcohol, which will remove most of the remaining water.
