Multipurpose cleanerThis kind of cleaner has a good ability to clean all kinds of dirt attached to the surface of building materials such as stone, metal, plastic, bedpans, spittoons, stoves, and chrome plating.On these surfaces, various dirt and rust spots are often attached. Silicate attachments are often attached to the surface of stone; rust spots of iron tetroxide are attached to the surface of steel; contaminants such as grease and oil are attached to the surface of plastics. To clean the iron tetroxide attached to the surface of steel, hydrogen fluoride solution is generally used. However, because hydrogen fluoride is a strong acid, it is unsafe to use. In addition, once it flows into the river, it will cause public hazards.The liquid cleaning agent introduced here not only has good cleaning ability, but also does not cause pollution. This detergent is prepared from water, sulfuric acid, acidic ammonium fluoride, neutral ammonium fluoride, oxalic acid, hydrochloric acid, hydrofluoric acid and other raw materials, and must be prepared in the following proportions and order. The order must not be reversed. Otherwise, there is a risk of explosion.1.Water……………………………………………… 20～50 liters2. Sulfuric acid…………………………………………5～10 liters3. Acid ammonium fluoride……………………………………1～ …
