BPI^® Neutralizers™ The fastest and longest lasting!
BPI® Neutralizer II™ removes color from lenses made from CR-39™ monomer. It has a self-cleaning formula that lasts longer in your tank than any other neutralizer. BPI® Neutralizer II™ works on most tints in an approved lens tinting system. A quart neutralizes hundreds of lenses. BPI® Neutralizer II™ is also available in quart or gallon sizes. It is not recommended for hard coated lenses.
The life of BPI® Neutralizer II™ is dependent upon how long it has been in the tank and how much work has been done. The action of BPI® Neutralizer II™ is to bleach some pigments and to take others out of the lens and into the neutralizing solution. Ultimately, the neutralizer solution becomes colored and slower in action. Provided the neutralizer solution remains clear, top off with fresh BPI® Neutralizer II™. If the coloring is significant, BPI® Neutralizer II™ can be left at operating temperature for a day without use and it should self-clean. If it fails to clean, throw it away and start with fresh undiluted BPI® Neutralizer II™. Rotation of the BPI® Neutralizer II™ with other tanks will keep the tanks cleaner and make tints last longer and more reliable. Thoroughly remove all traces of the neutralizer before using that tank for tints.
