The SPI Optical Cleaning Solution has been specially formulated for use in ultrasonic cleaners and for the thorough cleaning of delicate lenses and other optical parts. This product is available in a one pint (473 ml) concentrate. To use, mix one part concentrate to 10 parts of water, which will make 1.25 gallons of working solution. Using the concentrate instead of a pre-mixed ready-to-use product results in substantially lower shipping charges, something we believe is wasteful, and therefore we no longer offer a pre-mixed product.
