Cleaning the Filaments
1. Disassemble the lenses from filament base by removing the two socket cap
screws using a 1.5 mm. Allen wrench.
2. Clean the base near and between the filament posts with a piece of super
fine grade (400 grit) silicon carbide sand paper until most discoloration
disappears. Be very careful not to touch or deform the filament during the
process.
3. Using a sharp razor blade (or tip of utility knife), scrape off the same areas as
thinly as possible, until a surface similar in color to the original base is
exposed.
4. Wash off any powder and contamination with isopropyl alcohol or methanol.
Dry the filament before installing.
5. Clean the lenses with a cotton swab and isopropyl alcohol or methanol. It is
recommended to use a second swab after initial cleaning.
6. Reassemble the lenses onto the filament base.
