MAINTENANCE

DOME CLEANING

Clean the acrylic dome as necessary to maintain a clear picture. Be careful not to scratch the

surfaces of the dome.

Exterior Surface - Clean the dome’s exterior surface with a nonabrasive cleaning cloth and

cleaning agent that is safe for acrylic. Either liquid or spray cleaner/wax suitable for fine

furniture is acceptable.

Interior Surface (Except Chrome or Gold) - Clean the same as the exterior surface.

Interior Surface (Chrome or Gold) - The inside surface of a chrome or gold dome is easily

scratched. Use the following precautions to maintain the dome’s surface.

1. Always handle the dome from the outside of its circular flange.

2. Never touch the coated inside surface. The acid in your fingerprints will eventually etch

the coating if the fingerprints are not carefully removed according to the recommended

cleaning procedure in item 5.

3. If dust or other contaminants accumulate on the dome’s interior, remove the debris with

compressed air. Compressed air cans are available from photographic equipment or

electronic supply dealers.

4. If heavy residue accumulates and cannot be removed with air pressure, rinse with water

and immediately dry with air pressure so that water spots will not remain. Avoid wiping

the coated surface with direct hand pressure - it will easily abrade unless extreme care

is taken. Once scratched, the dome cannot be recoated.

5. If internal wiping is necessary, avoid hand rubbing. Instead, make a wick as follows:

Use a very soft paper towel. Roll a section into a tightly wound tube. Tear the tube in

half, and wet the fuzzy end of the wick with a solution of isopropyl alcohol diluted with

water. Hold the dome with its opening facing downward and wipe the interior of the

dome with the wet end of the wick. Use a circular motion, starting from the outside and

spiraling into the center. Use a new wick for each two passes over the dome.
