Cleaning a computer CPU - Do gauze pads with polyester in them cause ESD?
Valutek’s ESD polyester wiper is constructed from 100% continuous-filament polyester in a double-knit, no-run, interlock pattern with a conductive fiber designed to dissipate electrical charge.


But if wipe is not the same as above but your paste has silver in it, then ok.

You can use a razor blade then wipe carefully.  Lint free is good.
