| I'm trying to clean the grey coating - frit - from old CRT monitors, inside and out. I've found that alcohols (particularly methanol) clean it best,
but it needs to be scrubbed quite vigourously. I'd really like a method which will dissolve the frit (which contains mostly PbO, but also may contain
traces of mercury and cadmium) without scrubbing, so that I can automate the process and reclaim the chemicals for recycling. Anyone have any ideas or
experience in this? |
