Actually there are 3 types of detergents.
The detergents are the most important type of cleaning agent, and are usually mixed with water before use. They can be divided into three broad groups, dependent on the kind of solution they form, whether acidic, neutral or alkaline.
Acid detergents are generally based on phosphoric or sulphuric acid, and their use is rather limited. They are extremely effective in removing salts precipitated from water in hard water areas, and in cleaning aluminium where the acids readily remove the white scale that forms on the surface of the metal.
Neutral detergents comprise a wide range of materials that are mainly suitable for light duty cleaning. They are generally similar to household detergents, and their good wetting ability makes them ideal for the dispersal of grease and oil.
Alkaline detergents can vary in strength from those that are only a little stronger than the neutral types to ones that are strongly alkaline, consisting almost entirely of caustic soda, and requiring extreme care in use.
