Can you recommend a cleaner appropriate for fiber optics?
To clean fiber optic components using ultrasonic tanks, use a warm (45 deg C) 1% Liquinox solution followed by a thorough high purity water rinse (distilled, deionized or best of all, reverse osmosis water). To clean manually, use 1% Liquinox with appropriate lint free swabs or tools to clean surfaces followed by rinse wiping and possibly drying with isopropyl alcohol (drying solvent). You can also use a drying solvent such as isopropyl alcohol after rinsing when you clean with ultrasonics, although it is not entirely necessary. Liquinox has emulsifiers that are effective on a broad range of oils, dispersants that are effective on particulates, and contains rinse-aids and anti-redeposition agents that allow it to rinse away freely without redepositing any residues.
