Washing Spice
The purpose of washing is to disperse impurities off of the product or out of a solution containing the product and into an intermediate solvent.
Alkaline Solution Washing of Inactive Impurities
Most of the impurities that plague yields tend to be quite soluble in both alkaline aqueous solutions and non-polar solvents. To remove these impurities, an imbalance in equilibrium must be created between these two types of solutions, causing the impurities to disperse into a disposable solution from the solution containing the product. This procedure is commonly used for purifying product from extractions that utilize naphtha or heptane to obtain a whiter product.

Solvent Washing and Isolation of Active Impurities
Removal of active impurities generally relies strictly on differences of their solubility or insolubility in specific solvents. Most notably, Jungle Spice may be removed from DMT using particular solvents such as naphtha or heptane.
