PROCEDURE A: CLEANING AND LUBRICATING
Cleaning Brass & Stainless Steel Parts
1. Pre-clean 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 distilled 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 clean, low pressure filtered air and inspect closely to ensure proper cleaning and like-new condition.
Cleaning Anodized Aluminum, Plastic & Rubber Parts
Anodized aluminum parts and parts made of plastic, rubber or silicone such as box bottoms, box tops, dust caps, diaphragms,
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.
Cleaning Hoses
1. Hose fittings: Ultrasonically clean with soapy water*; vinegar OK on tough corrosion – ( only hose ends).
2. Run soapy water through hose if needed.
3. Thoroughly rinse with fresh water– (
hang with hose ends down).
4. Blow out hose before installing.
Lubrication and Dressing
All o-rings should be lubricated with Christo-Lube
®
MCG 111. Dress the o-rings with a very light film of lubricant and
remove any visible excess by running the o-ring between thumb and forefinger. Avoid applying excessive amounts of
Christo-Lube
®
MCG 111, 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.
CAUTION: Do not place plastic, rubber, silicone or anodized aluminum parts in acid solutions.
Doing so may alter the physical properties of the component, causing it to prematurely degrade
and/or break.
CAUTION: Silicone grease and sprays must be strictly avoided, since silicone does not provide
adequate lubricity in extreme weather conditions.
