Clean Internal Surfaces (Monthly)
When CA residue builds up on the internal surfaces, it may be necessary to remove it.
Residue on the main glass door is particularly detrimental to visual observation of
developing prints. Follow the procedure below to remove CA residue:
To gain better access to the stainless steel walls/floor inside the chamber, it is
recommended to remove the perforated floor, hanging bars, accessory items, and shelf
brackets (see Fig. 7-3). These items can be cleaned individually if desired, although
their surface area is much smaller relative to the interior walls and glass door.
1. Using a razor blade or paint scrapper with razor blade, scrape the internal
surfaces of the glass on the main door and interior walls.
Comparison testing on cleaning methods reveal that mechanical scraping
removes CA residue more easily, and reduces future build up on cleaned
surfaces. Chemical cleaners tend to leave a residue/film that attracts CA more
aggressively and therefore chemical cleaners are not recommended.
2. Remove the CA residue particulate from the scraping operation with a HEPA-
filtered shop-vac or similar vacuum. A dry cloth may also be used to
collect/gather the residue after scraping.
3. Replace all components removed by reversing the instructions above.
