Rather than picking and scrubbing to remove paste and particles of contaminations from microscopes, you can quickly and thoroughly restore them to a "like new" condition by using ultrasonic cleaning methods from L&R.
Use General Purpose Cleaner Non-Ammoniated in the main tank as a carrier bath. (Can also be used for cleaning lab glassware and instruments.)
Place column parts (pole pieces, brass parts, etc.) into 600 ml Beaker.
Cover parts with Hydro-Sonic Cleaning Solution Concentrate Non-Ammoniated or SF-50 Solvent-Free Degreaser Concentrate at the recommended dilution (see product label). Place into main tank using Positioning Cover.
Cavitate 5-10 minutes.
Rinse well under warm tap water.
Remove and dry in L&R Instrument Dryer.
Note: Only the removal of the paste and loose particles of contamination is expected ultrasonically. Ultrasonics will not remove carbon which is electronically hardened. In this application, demagnetizers are a natural for demagnetizing tweezers, tools, etc. subjected to the magnetic field in the pole piece.
