Cleaning & Lubrication Procedure
Lubrication and Dressing
All O rings should be lubricated with Christo-Lube MCG-111 or PerFluoroLube 20/1. Dress the O rings
with a very light lm of grease, and remove any visible excess by running the O ring between thumb and
forenger. Avoid applying excessive amounts of lubricant as this will attract particulate matter that may
cause damage to the O ring.
Caution: Do not place plastic and rubber parts in acid solutions. Doing so may alter
the physical properties of the component, causing it to prematurely degrade and/or
break.
Cleaning Plastic & Rubber Parts
Parts made of plastic or rubber 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 ltered air.
Cleaning Brass and Stainless Steel Parts
1. If required, pre-clean in warm, soapy water* using a nylon bristle tooth brush.
2. Thoroughly clean parts in an ultrasonic cleaner lled with a solution of household white distilled vinegar
(Acetic Acid) mixed with fresh water (max 50% vinegar). Clean ultrasonically for 5 minutes (max 10
minutes). DO NOT place plastic, rubber, silicone or anodized aluminium 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/1.7Bar) ltered air. Inspect
closely to ensure proper cleaning and like-new condition.
*Soapy water is dened as “household” grade liquid dishwashing detergent diluted in warm water.
