Amps covered with snoot/grime

[Sten]

I turn to you with my following concern for your experience and knowledge.

We had a fire in the room next to our rehearsal space. Fortunately flames did not get to our room, but through a (kind of) vent hole between the rooms a lot of snoot/grime* entered our room and covered all our gear including:
Bass poweramp (Peavey IPR 1600)
Two bass cabinets
Two Marshall full tube guitar amps
Marshall tube guitar combo
Marshall guitar cabinet
Drumset
Mixer, PA, two passive speakers for vocals
Projectmix I/O (mixer/interface)
a PC (one of the side covers was off)

The gear was not insured, but the institution whose room we used has coverage. We are highly doubtful about receiving some money from insurance, since the institution does not officially own any of this gear.

We wiped the grime off of everything. It was quite easy with all the cabinets: there was a cover of dirt on the top, but the sides were rather clean (the grime fell down vertically). We are very worried about all the amps of course. Grime conducts electricity and I see a high potential of short-circuits in circuit boards once we turn everything in (not done that yet!).

Have you had any similar experience? I am looking for guidelines for cleaning the equipment since we do not hope much insurance coverage. Nevertheless, if you have any recommendations of serving this issue to the insurance company (from your experience) I would appreciate them very much.

From what I see:
- The stink will almost never wear off, even if we move into new rehearsal space since all our gear is infected.
- There is a high risk of damage to the amps, mixers and PC due to possible failures in PCBs. That can happen during first switch-on or possibly later.
- The resale value of this is immediately decreased

What I personally hate the most is that I just bought a brand new 6x10" with carpet covering with intention to resell it next year that is now grimy and stinks as hell.

*I used Google translate to find these words in English since I do not use them on daily basis.

Smoke particles and "snoot" as you call it will eat electrical components, metal, and just about everything it touches. Over time it will create pock marks in the metal and eventually the components in the amps will fail. Your only hope at this point is to clean it as best as possible and use it until it breaks and try to get the best use for what you spent out of it. No one will really want to buy gear that smells of fire for that reason. You can try and retolex or recarpet the cabs but it isn't going to help with component degeneration.

The word is soot I believe, not snoot
