Today's work in a shot: cleaning switches after 5 years of continuous service

Today is "tha cleaning day": i cleaned about 15 3550/3500XL inline power and 2 2970.
The 3550s where in production for about 5 years without cleaning or power off...

Inside's dirt...

...and the full stack cleaned and stored

Well... incredible, only one 3550 has a failed fan, all the others still (noisly a bit) working ;-)
For cleaning i used a small portable air compressor and a 150h stud. (thanks Franz)
