• Avoid using compressed “shop air” as it often contains oil which can damage the optics or be hard to remove
• Use “Instrument grade” oil free air which has been filtered
• “Canned air” (or de-duster) in very short (< 1 second) bursts from a distance 8-10 inches from the optics can be
used. Short bursts from 8-10” away will minimize the transfer of any propellants/additives from the ‘canned air’
to the optics.
• If blowing does not work, clean the optics using isopropyl alcohol (IPA) and a lint free cotton swab
o Plan to use a minimum of two lint free swabs to clean the optics.
o The first IPA moistened swab is used to gently apply the IPA solution in a circular motion.
o Rotate the swab between your fingers as you work your way around the optics window in a circular
fashion to clean the optics. Use an additional ‘wet’ swab if additional cleaning is needed.
o Do not ‘double-dip’ by placing a used swab back into the IPA. This prevents prevent contamination of
the IPA from any material picked up from the optics.
o Use the second clean swab in a gentle circular motion to dry the IPA on the optics. Again rotate the
swab between your fingers as you gently move it over the surface.
o Stop when the majority of the IPA has been absorbed by the swab.
o Properly dispose of the used swabs.
Additional Tips
• Label the IPA as required & follow the Safety Data Sheet (SDS/MSDS) for IPA.
• Consider a dedicated IPA dispenser to avoid cross contamination from other activities.
• Do not use IPA with detergents or other additives.
• Use lint free cotton swabs. If you see streaking, consider another brand of cotton swab.
• If you “double dip”, the IPA can be compromised from material transferred from the instrument optics via the
swab.
• Adhesive use to hold the cotton to the applicator stick may be dissolved by the IPA and transferred to the IPA.
MicroCure Case
• Use isopropyl alcohol and a soft cloth to clean the case of the MicroCure
• Do not open the radiometer's case. There are no user-serviceable parts inside the unit
