The first pull is white beautiful perfect. It is frozen and the naptha is reused. I have come to the conclusion that the longer SWIM waits to do another pull the darker it turns the naptha. I just want to know the reason it turns brown and how SWIM could turn it back clear. Also sometimes the naptha doesnt turn brown it just becomes extremely cloudy and the results arent good then either. SWIM is tired of things never being certain no matter how consistent they have been every time. Here is SWIM'S personal tek

carlo rossi jug with most of a gallon of water (just above the label) measured it a long time ago dont remember how much it was. add 300 g MHRB shake vigorously until all chunks gone and nothing sticks to the sides after you let it settle then rotate it to check. add naptha roll not shake for an hour or so. turkey baste naptha into mason jars freeze for 6 hours usually overnight. pour off naptha put jars back in freezer upside down for a few hours and scrape them.
