Cleaning the fiber with high purity of Isopropyl Alcohol is necessary to create a good bounding with the fiber. Lower grade alcohols contain H2O which could leave miniscule small drops on the fiber which might be captured when inserting the fiber into the epoxy/ferrule. When heating the ferrule the water needs to outgas, creating air-bubbles in the epoxy.
