Brass and Stainless Steel Parts
1.
Preclean in warm, soapy water* using a nylon bristle tooth brush.
2.
Thoroughly clean parts in an ultrasonic cleaner filled with soapy water. If there are stubborn deposits, household white dis-
tilled vinegar (acetic acid) in an ultrasonic cleaner will work well. DO NOT place plastic, rubber, silicone or anodized aluminum
parts in vinegar.
3.
Remove parts from the ultrasonic cleaner and rinse with fresh water. If tap water is extremely "hard," place the parts in a bath
of distilled water to prevent any mineral residue. Agitate lightly, and allow to soak for 5-10 minutes. Remove and blow dry with
low pressure (25 psi) filtered air, and inspect closely to ensure proper cleaning and like-new condition.
Anodized Aluminum, Plastic & Rubber Parts
Anodized aluminum parts and parts made of plastic or rubber, such as box bottoms, box tops, dust caps, etc., may be soaked
and cleaned in a solution of warm water mixed with mild dish soap. Use only a soft nylon toothbrush to scrub away any deposits.
Rinse in fresh water and thoroughly blow dry, using low pressure filtered air.
Hoses
If buildup of corrosion is severe, it is permissible to soak only the hose fittings in the ultrasonic cleaner as needed, and not allow
any solution to enter the hose. Rinse in fresh water and allow to dry with the cleaned ends hanging down. Blow filtered air through
them prior to installing onto the regulator.
Lubrication and Dressing
All o-rings should be lubricated with Christo-Lube
visible excess by running the o-ring between thumb and forefinger. Avoid applying excessive amounts of Christo-Lube grease, as
this will attract particulate matter that may cause damage to the o-ring.
*Soapy water is defined as "household" grade liquid dishwashing detergent diluted in warm water.
