What is denatured alcohol?

Denatured alcohol is ethyl alcohol (ethanol) that has been mixed with other substances to make it unfit for human consumption. This is done by adding various chemicals, such as methanol, isopropyl alcohol, or pyridine, which give the mixture a foul taste and odor. Denatured alcohol is commonly used for industrial purposes, such as cleaning surfaces, as a fuel source, and as a solvent in various products. It's important to note that denatured alcohol is not safe to ingest and can be toxic if consumed.
