Denatured alcohol is ethanol that has been mixed with toxic additives to make it unsuitable for consumption. Here are some of the uses of denatured alcohol:

• Fuel: Denatured alcohol is used as fuel for alcohol burners and camping stoves. It is also used as a clean-burning fuel for marine stoves.

• Solvent: Denatured alcohol is used as a solvent in a variety of commercial and industrial environments. It can dissolve grease and stains, remove light scratches from surfaces, and clean metal parts and surfaces.

• Cleaning agent: Denatured alcohol can be diluted with warm water to clean and sanitize hard surfaces such as tables, sinks, stoves, and countertops. It can also be poured directly into the toilet to sanitize the bowl. Its disinfectant properties make it useful for cleaning and disinfecting hospital surfaces and removing bacteria in sanitizers.

• Medical applications: Denatured alcohol is used to disinfect and sterilize medical equipment.

• Cosmetics: Denatured alcohol is used in cosmetics and skincare products such as toners and makeup brush cleaners as a drying agent.

It is important to note that pure ethanol is required for food and beverage applications and certain chemical reactions where the denaturant would interfere.
