You have to clean it up real well since the carbon is conductive, scrub
every bit of it off that you can. Then get a tube of HV dielectric grease,
normally automotive parts stores sell it in the ignition section, just smear
the suction cup underside with it and put it back together.


And make to discharge the CRT before you touch it!

Thanks guys. I scrubbed it a bit more with acetone and toothbrush and
all arcing has now stopped. I should be able to get the HT grease
locally so I think I'm good to go.

Thanks,
