What does formalin smell like?
Formaldehyde is a colorless chemical with a strong pickle-like odor that is commonly used in many manufacturing processes. It easily becomes a gas at room temperature, which makes it part of a larger group of chemicals known as volatile organic compounds (VOCs).
Is formalin a disinfectant?
Formaldehyde is used as a disinfectant and sterilant in both its liquid and gaseous states. ...
