How do I clean metal shavings from modelling files?

One of the headaches modelmakers and scratchbuilders face is how to keep files clear of accumulated metal filings and shavings. Those built-up burrs and shards can quickly render a file's teeth blunt and ineffective if not regularly removed.

The traditional method is to simply rap the file's surface against the edge of the workbench or vice. This can effective dislodge some of the debris, but invariably many particles remain stubbornly embedded between the teeth.

A much better approach is to use a dedicated file cleaning brush. These stiff-bristled brushes are designed specifically to scour out all the trapped filings from a file's grooves. Simply brush firmly along the length of the file while holding it at an angle, sweeping out the offending detritus.

For an even more thorough cleaning, you can make up a mild solvent bath using white spirit or methylated spirits. Suspend the files in the solvent for 10-15 minutes, which helps loosen any compacted filings and grime. Then give them a final brushing once removed from the bath.

Whichever method you use, it's crucial to remember to always brush in the direction of the file's teeth to avoid damaging or bending them. A few moments of regular maintenance will ensure your files stay sharp and effective.
