Re: Cleaners...
In another company the cleaners wet-mopped everything and as last step the computer screens.
Oh yes, I remember back in the 80s we had just got some (Apollo Domain) workstations in - for the day, powerful 68020 systems ! With what was, for the day, huge 19" colour screens. Sure enough, one morning we came in to find a dried on layer of wiped on "mud". By the time the cleaners had gone over a football pitch sized office, the water they had in the bucket was "a bit brown". Yes, we had words with the cleaners and they didn't do it again.
