This is a reusable quick-cleaning solution for stubborn bore contaminants. Please note, if it is undesirable to access the bucking in cleaning, and the window is large enough to catch the scraper, it may be cut in half and fed backward though the bore for slightly reduced cleaning capability.
This concept arose out of discussions regarding the removal of more stubborn dirt and contaminants from the bore as part of the cleaning process. Rather than merely smearing in and dragging along contaminants, this attempts to scrape off and push ahead things which would not normally be removed easily. This in particular came up as a subject of discussion when a user was having difficulty with a "waxy" lapping compound becoming adhered to the bore.
