ATC had a small industry of AATC's cleaning perspex totes and GCA plaques ... I was just glad someone else did it! No idea what they used, but it was in small red 250 tins [or Imperial equivalent]
We used to have "Cloths, Cleaning" to wipe radar tubes etc. My contribution to the Defence Budget as a SATCO was to suggest to my SNCO Admin that instead of binning them when filthy, they might be laundered. He complied, somehow, probably at his own expense ... because Dave was like that.
