Cleaning Stainless Steel
Material Description: Stainless steel is extremely durable, and maintenance is simple and inexpensive. Proper care, particularly under corrosive
conditions, is essential. Always start with the simplest solution and work your way toward the more complicated.
Routine cleaning: Daily or as often as needed use a solution of warm water and soap, detergent, or ammonia. Apply the cleaning solution per the
manufactures instructions and always use a soft cloth or sponge to avoid damaging the finish.
Stubborn Stains: To remove stains from stainless steel, use a stainless steel cleaner and polish such as Ball
abrasive. Always follow the manufactures instructions and apply in the same direction as the polish lines.
Never use ordinary steel wool or steel brushes on stainless steel.
Always use stainless steel wool or stainless steel brushes.
Special Situations for Material
Fingerprints and Smears: To remove fingerprints or smears use a high quality stainless steel cleaner and polish in accordance with the
manufactures instructions. Many of these products leave a protective coating that helps prevent future smears and fingerprints.
Grease and Oil: To remove grease and oil, use a quality commercial detergent or caustic cleaner. Apply in accordance to the manufactures
instructions and in the direction of the polish lines.
Precautions: Avoid prolonged contact with chlorides (bleaches, salts), bromides (sanitizing agents), thiocyanates (pesticides, photography chemicals,
and some foods), and iodides on stainless steel equipment, especially if acid conditions exist.
Do not permit salty solutions to dry and evaporate on stainless steel.
The appearance of rust streaks on stainless steel leads to the belief that the stainless steel is rusting. Look for the actual source of the rust in some
iron or steel particles which may be touching, but not actually a part of the stainless steel structure.
Strongly acidic or caustic cleaners may attack the steel causing a
reddish film to appear. The use of these cleaners should be avoided.
Brand Names: Use of brand names is intended only to indicate a type of cleaner. This does not constitute an endorsement, nor does the omission of any brand name cleaner imply its
inadequacy. Many products named are regional in distribution, and can be found in local supermarkets, department and hardware stores, or through your cleaning service. It is emphasized
that all products should be used in strict accordance with package instructions.

Solution
1. Check all tubing and fittings for proper assembly.
2. Tighten compression nut at 1/8" tubing connection.
3. If air leak persists:
A. Remove the two screws securing the foot button escutcheon and check the 1/8" elbow
connection behind the pushbutton assembly.
B. Make sure the screw holding the elbow is tight and the fitting in the elbow is firmly hand
tightened.
C. Make sure the fitting is pushed firmly into the elbow.
4. If air leak persists:
A. Disconnect the tubing by pressing down on the plastic ring at the top of the fitting and
pulling it out.
B. Trim 1/2" off squarely with a razor-knife.
C. Push tubing back into the connector until firmly seated.
5. If leak still persists:
A. Loosen the compression nut on the air valve inside the pedestal.
B. Pull out the the 1/8" tubing and trim 1/2" off squarely with a razor-knife.
C. Push tubing back into the valve until firmly seated and hand-tighten the compression nut.
1. Unscrew the valve clamp nut on the top of the foor valve.
2. Remove valve cover. If the diaphragm/magnet assembly comes out with the cover, gently peel
the diaphragm away from cover, taking care not to damage it. Inspect the diaphragm for any holes
or tears. If damaged, replace it.
3. Insert the diaphragm/magnet assembly back into the valve, but leave the cover off.
4. Gently press the diaphragm fully. If the valve does not activate, the entire diaphragm/magnet
assembly needs to be replaced.
