Smoke damage to switch's and server

Hi

We had a minor fire the other day and a lot of smoke got into our server
room, which was then drawn into my servers and switch's. you could tell
there was a lot of smoke as the back of the fans were covered badly in soot,
everything stayed running ok tho!

there was a lot of soot inside the machines, covering practically all the
components, all servers and switches have been cleaned out with air dusters,
but i'm just trying to get opinions on the long term damage if any?

in the meantime tho i'm trying to get them all replaced under insurance, as
2 of the switch's fans have already failed and have had to been stripped and
cleaned out!

just wondering!

Chris
