Cleaning solution methylene chloride has a boiling point of 39.8℃. It is an organic substance with a molecular formula of CH2Cl2. It is a colorless and transparent liquid with a pungent odor similar to ether. Slightly soluble in water and soluble in ethanol, it is a non-flammable low-boiling point solvent under normal use conditions. When its vapor becomes a high concentration in high-temperature air, a weakly flammable mixed gas will be formed. It is often used to replace flammable petroleum ether. etc., are used in a variety of industrial processes including paint stripping, pharmaceuticals, paint stripper manufacturing and many different industries such as metal cleaning and degreasing.

In the laboratory, Cleaning solution methylene chloride is used to extract chemicals such as steroids, antibiotics and vitamins from plants or food. Medical equipment can be cleaned quickly and efficiently with methylene chloride cleaners without causing corrosion problems or damaging heat-sensitive components.

Cleaning solution methylene chloride is a common solvent in paint strippers for liquid-liquid extraction in laboratories. Acute toxicity results from central nervous system depression and death due to exposure. The main route of exposure is inhalation, but absorption through the skin is also a problem. Acute inhalation produces central nervous system depression and, at very high concentrations, anesthesia and ultimately respiratory failure and death. As it is metabolized to formaldehyde and carbon monoxide, prolonged exposure can produce carbon monoxide-type symptoms such as headache, nausea, vomiting, confusion, and dizziness. Skin contact can cause irritation and chemical burns.
