Fire Suppressant Chemicals in a lapotp. What to do???

A local ham radio operator got hit by the serial arsonist who's
been torching cellphone towers in the Vancouver, WA area.
Good news is that the tower was mostly unharmed. Bad news is that the
house is a total loss...but that's another story.

Fire department put it out with some kind of fire suppressant foam.

The thinkpad laptop was on at the time. Inside it's quite a mess.
localized corrosion all over the place. You can sure tell which pins
were the power pins on each IC. Memory contact pads are seriously
eaten up. I washed it a bunch in simple green and alcohol and managed
to get everything but the keyboard fixed up.

But we've got a LOT more electronic equipment to fix up.
Anybody know what's in this foam stuff and have ideas on best way to
clean it up? It's likely that at least some of the equipment will
be sittig there for weeks until we can get around to it. Should we try
to hose it off if it's gonna be sitting for a while?

I called several local fire departments. I got the serious runaround.
Doesn't sound like they don't know what's in it. Sounds more like they
don't want to tell me what's in it.

Google got me lots of hits on effects on furry creatures, but nothing
related to cleaning up electronic equipment.

I did find one MSDS that mentions:

Composition
Substance CAS No EINECS No Risk Phrase
Ammonium polyphosphate 68333-79-9 269-789-9 none 100
(polyphosphoric acid, ammonium salt)

That can't be good...

Suggestions for treatment?

Anybody ever tried to disassemble a thinkpad 600E keyboard? Looks like
it's glued together???
Thinkpad keyboard for sale?
