1, a solvent-based metal surface cleaning agent, is simply insoluble in water and cannot be used with water; Such as kerosene, diesel oil, gasoline, trichloroethylene, chloroform, white electric oil, alcohol, hydrocarbon cleaning agent, carbonated water, white electric oil substitute, n-hexane substitute, gun water substitute, trichloroethylene substitute, etc. It's all solvents.

2. Water-based metal surface cleaning agent is a simple water-soluble metal surface cleaning agent, which can be diluted with water. 1, acidic metal surface cleaning agent means that the PH value is below 7; Generally, rust remover and paint remover are acidic.

2. Neutral metal surface cleaning agent means that the PH value is about equal to 7; Such as neutral cleaning agents, most solvent-based metal surface cleaning agents are neutral.

3. Alkali metal surface cleaning agent means that the PH value is greater than 7; Most water-based metal surface cleaning agents are alkaline.
