This is a two-part filtering process. The first uses sand over catalytic, activated carbon over a tightly-rolled cut piece of washcloth. (see photo) This results in the orange chemical in the bottles on the right. In the second pass, the empty bottle (lying down in photo) is filled 2/3 full with catalytic, activated carbon over a similarly-coiled piece of wash cloth. This pass results in an exceptionally clear, finished product.

PLEASE NOTE: CATALYTIC MEANS 'HEAT!' PLEASE WEAR GLOVES AND EYE- PROTECTION AND POUR SLOWLY. THE HEAT SHOULD NOT MELT THE BOTTLE, BUT IT GETS VERY WARM!

PLEASE CONSIDER YOUR ENVIRONMENT IF THERE IS SPILLAGE!

Give the slow-filtering time to work. It can take two hours for a bottle set-up like the one in the photo.

Once you have finished the filtering process, leave the bottle set-up in a safe place for future use. Expect to lose approximately 1/4 bottle of cleaner between painting process and filtering.
