Klean Strip Green Paint thinner is better for the environment because it contains no hazardous air pollutants, no ozone-depleting chemicals and is low-VOC. It is a new, revolutionary, safer paint thinner formula that thins, cleans and preps. It is milky white in color and can be used to thin any color of oil-based paint, stain and varnish without affecting the color of the dried paint.
The milky white color must be mentioned on a visible place of the can. Using it with another color than white or varnish is a problem. When opened it is a surprice and back to Kooyman there was no help.
