Immersion Overview Immersion cleaning refers to dipping or soaking parts in a liquid bath, usually at room temperature with no agitation. The chemistry in the bath must be matched to the soil on the part because the process depends mainly on chemical solvency. It is the least aggressive form of wet cleaning and works best for removal of soluble fluids and soils. Agitation of the bath or addition of heat usually increases the effectiveness of the process. Common methods for adding agitation to the bath include megasonics, ultrasonics, spray under immersion, and submerged spargers. Heating elements may be submerged in the bath or mounted on the outside of the tank. Immersion tanks can become heavily loaded with soils in a short time. If soil loads are high, separation and filtration systems probably will help. A prewash station will usually increase the time between bath changes.
