Researchers tested the effects of various metals on human skin and found that what smells is not the metal, but the rapid interaction of skin oils with iron, copper and brass. The chemical reaction causes new, strongly scented gaseous compounds to form.
The characteristic ``metallic odor'' is caused by a copper ion catalyzed oxidation of fatty acids in skin oils that produce characteirstic odor compounds which you can detect at ppb levels. Brass contains copper from which the copper ion containing patina forms.
It called for a mere two ingredients: baking soda and lemon juice. I don't always have fresh lemons in the house, but I usually do keep a little bottle of lemon juice in the refrigerator. If you don't have lemon juice, you can substitute vinegar, but your kitchen will not smell nearly as delicious.
Avoid brass, copper, and bronze and you should be fine. Aluminum, stainless steel, titanium, and zirconium all don't really leave an odor on your fingers.
Phantosmia may be caused by a head injury or upper respiratory infection. It also can be caused by aging, trauma, temporal lobe seizures, inflamed sinuses, brain tumors, certain medicines and Parkinson's disease. Phantosmia also can result from a COVID-19 infection.
Smelling smoke, or experiencing phantom smells that are not actually present, can be a symptom associated with certain types of brain tumors. These olfactory hallucinations, known as phantosmia, can occur when a tumor affects the brain regions responsible for processing smell signals.
Health Hazards: There are no immediate health hazards associated with this product. If highly heated, fumes from the product may also cause metal fume fever.
One of the main compounds responsible for this odour is 1-octen-3-one, an organic molecule that has a strong metallic odour. This compound is formed when iron catalyses the breakdown of fatty acids in our skin. Other compounds, such as aldehyde and ketones, can contribute to this characteristic aroma.
While brass is generally safe for many, it's not considered hypoallergenic. Brass, a copper and zinc alloy, may cause allergic reactions, especially in people allergic to nickel. If nickel is used in brass manufacturing, it can trigger skin irritation or allergic reactions in sensitive individuals.
Ketchup, tomato paste, and tomato sauce all work equally well. Apply a layer of whichever one you choose to your brass and leave it on for an hour. Then wash with warm water and dish soap and let it dry. This method is easy, economical, and effective at cleaning your brass.

New horns smell like oil and the materials they are made of, and with use they begin to smell like the player's breath and verdigris, a type of rust particular to brass. There are also times when the mouthpiece can start to smell because of accumulated dirt.
Copper, which makes up about 60 percent of brass, turns green over time as it oxidizes. So, it's only logical to assume that brass turns green over time, too. However, it's highly unlikely for this color change to spread onto your skin.
One such compound in particular, called 1-octen-3-one, which is found in the vapours above skin touched by iron, is particularly smelly. Humans can detect it at very low concentrations, and experience it as a mushroom-like, metallic odour.
Your body naturally contains trace amounts of metals like iron, copper, and zinc. When these metals mix with sweat, they can produce a metallic odor. Hormonal changes, certain medications, or even your diet can affect the levels of these metals, leading to a stronger smell.
And when you touch brass and then rub your hands together, you'll notice a metallic smell that is caused when the metal interacts with your perspiration. The active elements in brass—copper and zinc—contribute to the taste and smell. That explains why brass jewelry is not popular – it leaves an aroma on your skin.
Still, it's possible that things like diet, medical conditions or a bacterial buildup on the skin could be causing odor, Kopelman says. Hyperhidrosis, the medical term for excessive sweating, could also contribute, because bacteria thrives in moist environments.
Chronic brass poisoning has been reported and is characterized by the appearance of anemia and green line at the base of the teeth (due to a large proportion of copper) along with palpitation, dyspnea on exertion, dyspeptic symptoms, anorexia and epigastric pains, nausea, vomiting, and colic [4].
The signs and symptoms are generally flu-like, such as chills, myalgia, chest pain, non-productive cough, metallic taste in the mouth, leukocytosis, headache, fatigue and malaise. A sweet or metallic taste in the mouth may also be reported, along with a dry or irritated throat which may lead to hoarseness.
One such condition is byssinosis, a collection of respiratory symptoms elicited by exposure to raw, nonsynthetic textiles during their manufacturing process. Over the years, byssinosis has been referred to as cotton worker's lung, brown lung disease, Monday fever, and mill fever.
Smelling things that aren't there is called phantosmia. It can be unpleasant and affect how things taste. But it isn't usually serious and may go away by itself in a few weeks or months. See your GP if the strange smell doesn't go away in a few weeks.
