We have a customer that runs a metal shop. Lots of welding and laser cutting, painting, etc. Their KSU is nasty due to the fumes and a brown sticky crud that sticks on and in and all over the surfaces.
The KSU is in a phone closet, but still gets the crud. (For the record their "clean" office area has the same film like crud and the window washers really love it. NOT!)
We can wipe down the outside of the KSU with no problem, be there is not really a good way to clean out the inside.
Any and all suggestions on cleaning would be appreciated?
