Fiberglass contact cleaner

Specially for cleaning oxidized or dirty contacts, e.g. connection surfaces on printed circuit boards or battery contacts. It is also used in model making to sand away excess adhesive residue.

When working with this pen, only the fibreglass tip should come out of the pen (abrasive surface).

Attention: clean up the 'grind' afterwards, because during cleaning some fibres can break and eventually end up in the skin.
