First Contact WSP1 - Water Spot Pre-Treatment 2.8 oz Bottle
This 2.8 ounce (82ml) 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.
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 the document demonstrating proper use in the Downloads tab. 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.
