How to Use Salt to Separate Purell
- 1). Combine 4 oz. of hand sanitizer gel with 1 tsp. of table salt.
- 2). Cover a cup or bowl with several layers of cheesecloth or a similar porous material.
- 3). Strain the mixture through the cheesecloth. The liquid ethyl alcohol will pass through, leaving the congealed salt and glycerin behind. In one experiment, the filtered liquid that resulted from this process was 70 percent ethyl alcohol and 2 percent isopropyl alcohol by volume.
