Aurora Innovations Sap Off! Soap (SOS)A lot of people don't realize that the best soap in our industry is brought to you by Aurora Innovations. This stuff should be next to every grower's sink! Years ago, we discovered that this proprietary blend of mineral oil, citrus extracts and grit was exactly what was needed to get tough sticky resins and oil based compounds off of skin without the use of harsh astringent chemicals. Just remember to always use Sap Off Soap BEFORE you use any water.
