New and Improved! This 8 ounce (225mL) spray bottle of water based cleaner is a pretreatment for use in conjunction with First Contact Polymers to remove water based stains, spots, pollen, etc. The pretreatment has been reformulated to better coalesce with First Contact Polymer. NOTE: Pretreatment will not nicely coalesce and is not recommended for use with our Water Resistant Formula Polymer.

We recommend cleaning first with First Contact Polymer Solution and if water based deposits weren't removed then use the 2 Step cleaning process of pretreatment and First Contact. For a description of the process please see this document demonstrating proper use. Also, watch the videos for water spot removal from a refractor or from a SCT corrector plate

For mounted optics you also may want to consider ordering orings to control both the polymer and pretreatment flow. See our oring web page for a selection of orings from small to custom sizes!
