Synopsis

Smoke odors linger due to particles clinging to surfaces. While air fresheners offer temporary relief, vinegar provides a chemical solution by altering odor molecules. This accessible household item offers a gradual, persistent way to neutralize smoke smells, though intensive cleaning and ventilation may be needed for deeply embedded odors.

The odor from smoke usually persists even after the smoke clears, since the particles in smoke are very small and stick to the surfaces of objects in the room. Objects such as walls, curtains, carpeting, and upholstery will hold onto these substances and release them back into the air, thereby perpetuating the odor. Most individuals opt for air fresheners, though they tend to be more like temporary solutions. They do nothing much to eliminate the actual cause of the odor, and thus, once the air freshener stops working, the odor begins to re-emerge. To completely eliminate odor-causing substances, one must engage in chemical reactions, and in this regard, basic substances such as vinegar are useful.

Vinegar starts interacting with odor molecules

The acetic acid in vinegar alters the molecular composition of some odor molecules. Once poured into a container, it slowly emits its vapors into the atmosphere around. The released vapors act on the molecules, causing the smoky odor, and weakening the smell gradually. Contrary to sprays, which simply release a new odor that masks the previous one, vinegar works differently and alters the behavior of odor-causing particles, as suggested by PubMed and ScienceDirect. Its effect is slow and gradual, but it persists as long as vinegar is present. It makes vinegar a good solution to deal with lingering but not overly strong smells. The strong acetic smell tends to disappear soon after evaporation.

Why do people turn to this method?

The advantage of the use of vinegar is due to its easy access and convenience. There is no need to buy equipment, install anything, or incur any extra expenses since all you need is a common household item. Placing a bowl in the room will start acting by itself. Thus, this option can prove helpful for those who prefer simple ways to solve their problems. Moreover, it does not involve the use of artificial aromas that might be too intense for some people.

You need to be aware of its limits

However, despite its beneficial properties, vinegar does not solve all problems on its own. If there is strong, long-lasting contact with smoke, odors may have deeply penetrated fabrics, which will require a more intensive wash, as per an article in MDPI Atmosphere. The ventilation system will be helpful here, as fresh air will remove both the smell of vinegar itself and the altered smell particles. When dealing with large spaces, one may use several bowls to achieve better results. One should not heat up vinegar, as it may become more odorous. This way, vinegar will provide continuous, effortless cleaning from lingering smoke smell.
