Use the file cleaner brush.16.Never store files with lubricants or rust-preventivecompounds on them. Wrap each file in a water-proofed barrier wrapping paper and place the filesin racks or boxes so that the faces or edges of thefiles will not touch each other.12.Never use a file without a securely attachedhandle (3), unless it is of the Swiss pattern type.13.Do not use files for any other use except filing.14.Do not oil files.
