Process for cleaning camera filters:

Wash tank 1 was allowed to reach the required temperature and degassed for 10 minutes before cleaning.

Stainless steel 304 wire was used as a fixture to support the lens whilst cleaning; this enabled the lens to stand up without floating. The part was then submerged in the Galvex 20.01 and washed for 3 minutes.

Next the part was rinsed in tap water for 1 minute; this is necessary as to remove any remaining cleaning fluid which may cause staining. Finally the part was dried in a hot air dryer set at 65°C for 5 minutes.

Note: The lenses are not 100% spot free, this is due to the high mineral content in the tap water. To achieve a spot free finish an additional DI water rinse would be required.
