If your solvent goes acidic, neutralizing your degreaser is normally req​uired to prevent contaminating new solvent. 

3) Bad or Exposed Heater Elements

Baked on contaminants can build up on the Cal-Rods of heater elements. If not cleaned properly and on a consistent basis, this build up can cause “Hot-Spots”. These “Hot-Spots” will eventually deterate the metal shields of these rods causing them to short and in turn “Flash Over”.  This “Flash Over” is a fast burning of the flammable contaminants in the solvent and normally lasts for a only a few brief seconds (but long enough to cause an acidic condition).
NOTE: This “Flash Over” can also occur if the solvent level drops below the heater elements.  An exposed Cal-Rod has no way to dissipate the energy supplied to it to heat the solvent. Therefore, the Cal-Rods will turn red and again burn any flammable materials in the solvent and vapor causing an acidic condition.

2) Moisture in the Solvent

Most, if not all, degreasers have a water separator. If the build up of water (from water based coolants or just humidity pulled from the air) is not removed
consistently, this water mixed with the solvent can become aggressive and break down the stabilizers in the solvent causing acidic conditions.

         Three Main Causes of Acidic Solvent​

1)Soft Metals 

All solvents have stabilizers in them to keep them from going acidic. If soft metals such as aluminum (parts or chips) are left in the solvent for an extended period of time the metals will start to break down the stabilizers in solvent which intern may cause the solvent to go acidic.
