Because of the chemical make up of Chem-Dip, which contains Methylene Chloride and Cresylic Acid, disposal must conform to the rules of your community for proper disposal of Hazardous Waste. To defer this disposal and reduce the amount of chemical, several of our customers use the spent product as a "pre-rinse" to use before dipping into a new bucket of Chem Dip. This allows the part to soak up a little of the spent solvent, which pre-softens some of the residual material on the part. Proper storage of Chem Dip is also a very important consideration. Because of the high Di-electric chemistry, some discharge "electrolysis" may result from storing directly on concrete or on a metal rack staged on concrete.
