The 1.25MM NEOCLEAN sticks (CSK-01) are effective for cleaning residues and dust based contamination on fiber optic end-faces. It is the ideal tool for Fiber To The Antenna (FTTA), ODAS, Data Centers, Military, Aerospace, and Industrial applications. Its fabric cleaning tip allows for cleaning eliminates the need for a solvent. The notched handle is customizable for working in tight spaces. This cleaner will clean CS, SN, LC, MU, CD-2, ARINC 801, VITA 66.2 and many other SN and LC based connectors. The 1.25MM NEOCLEAN stick is effective for MIL DTL 39888 cleaning the 1.6mm socket termini MIL PRF 29504/5. The sticks are RoHS and REACH compliant.

The cleaning tip is made of the same micro woven fabric that is used for the cleaning ribbon in cassette cleaners. The individual fibers diameter is 2μm. These micro fibers are woven together in a check formation. This makes design creates a capillary and sweeping effect from pulling away and trapping dust particles and residues. The micro woven tip gives it a superior cleaning performance over other materials like foams and sintered strands tips that require the use of a solvent to make them effective.

The sticks are designed to be used ti clean one end face and then discarded. The reason Senko recommends against use the same stick multiple times is to avoid the possibility of transferring the contamination. The contamination that was wiped from the first ferrule is pulled into and trapped in the cleaning fabric tip. If the stick is used repeatedly, the material could come loose from the movement when the tip us reused.

The cleaning sticks advantages are the ability to clean the inner side walls of an adapter sleeve or socket. The cleaning tip of the stick spreads out and conforms the curve of the ferrule end face. This makes the stick’s effective cleaning region larger than a click style cleaner. This could be helpful for end faces that have been subjected t heavier levels of contamination.
