CYLINDER MAINTENANCE
Cleaning Interval:
Interior—6 -12 months; Exterior—As Needed
For outdoor applications and during periods of extreme inclement weather, more
frequent maintenance may be required.
A conventional lock spray may clog a mechanical cylinder and damage an electromechanical cylinder. For locks
in frequently used doors or locks exposed to harsh environmental conditions we recommend more frequent
lubrication.
To avoid any disruptions in functionality due to condensation and/or freezing, maintenance should be scheduled
before the winter period in cold climates.
WARNING!
Never use grease, oil or graphite-based lubricants in locking cylinders, as these lubricants cause disruptions in
functionality and clog up the mechanism.
The contacts on the cylinder face should be cleaned using DeoxIT cleaning pens and a towel.
Cylinders may also be cleaned using DeoxIT spray and a soft bristle brush.
1. Using the DeoxIT cleaning pen, gently depress the pen tip against the contacts until the pen
tip is saturated allowing the solution to “wet” the contact.
2. With the contacts “wet,” rub the contact surfaces clean using a towel to remove any
accumulation of oxidation, grime, etc., or any excess cleaning fluid.
3. Inspect the contact surfaces. If black residue, grime, etc., are visible on the contacts and/or
cylinder face, apply DeoxIT Cleaning Spray to a soft bristle brush and clean the cylinder face
with the brush. Repeat steps 1 and 2 until clean.
4. Apply a light coating of Fluid Film to protect the contacts. Using the aerosol version, apply a
quick spray and then wipe gently with a dry cloth. The Fluid Film can also be applied to the
cloth first and then used to wipe the contacts.
