Thankfully, though, we just discovered a new hack for melting away ice on car windows thanks to good-old Reddit — and an expert we talked to says it's actually a very smart idea.
Turns out, rubbing alcohol has a much lower freezing point than water (128°F below 0), so it speeds up the melting process and prevents the surface from icing up in the future, Rossen says.
Rubbing alcohol, also known as surgical spirit in some regions, refers to a group of denatured alcohols commonly used as topical antiseptics. These solutions are primarily composed of either isopropyl alcohol (isopropanol) or ethanol , with isopropyl alcohol being the more widely available formulation.
Isopropyl alcohol (IUPAC name propan-2-ol and also called isopropanol or 2-propanol) is a colorless, flammable, organic compound with a pungent alcoholic odor. [9]Isopropyl alcohol, an organic polar molecule, is miscible in water, ethanol, and chloroform, demonstrating its ability to dissolve a wide range of substances including ethyl cellulose, polyvinyl butyral, oils, alkaloids, and natural ...
Antifreeze is commonly consumed due to its sweet taste cause by the ethylene glycol, [38] and is also commonly consumed as a surrogate alcohol due to its high alcohol contents. To prevent consumption due to taste, many brands have bitter additives, but many [ 39 ] [ 40 ] [ 41 ] studies do not support the idea bitter additives reduce ingestions.
Never pour hot water onto your windshield to melt ice. The thermal shock, say experts, can crack and shatter the glass, leading to an expensive repair. Deicing solutions help, but can remove car wax
Modern ignition interlock devices use an alcohol-specific fuel cell for a sensor. A fuel cell sensor is an electrochemical device in which alcohol undergoes a chemical oxidation reaction at a catalytic electrode surface to generate an electric current. This current is then measured and converted to an alcohol equivalent reading.
