I have previously discussed the basics of soak tank cleaners. There are 2 different types – hot and cold soak tank cleaners. Cold tank cleaners cost more initially but have much lower running costs.
It’s really important to look after cold tank cleaners to make sure that the chemical does not evaporate. All cold tank cleaners are made up of two separate layers - one solvent and one water –based. When not in use it is vital that this cleaning chemical is properly sealed so that there is no evaporation. The ratio between the water and solvent layer must be maintained. The water layer is there to act as a water seal to prevent evaporation of the solvent layer below. There needs to be 18% water and the rest should be solvent. To ensure that this ratio is maintained the rod test is very effective. Simply take a metal rod that has been painted. Put this rod in the drum of soak tank cleaner and push it down until it touches the bottom. When you pull the rod out the part where the paint has been removed will show how much of the drum is filled with solvent.
To use soak tank cleaners, both hot and cold, you will need to have a dip basket. This dip basket will need to have some holes in it so that when the basket is removed from the drum the chemical does not come with it. This basket will be lowered into the soak tank and left there for anything from 20 minutes to 2 hours. After enough time has passed to clean the items in the basket, raise the basket from the drum and allow for any remaining chemical to drain out of the holes in the basket back into the drum. The parts that were in the basket will need to be thoroughly rinsed with water before repainting or working on them.
