What causes yellow stains under the arms?

Yellow stains under the arms often occur as a combination of sweat and deodorants. When we sweat, our body produces natural oils and salts that can react with the chemical ingredients in deodorants. This reaction can result in the formation of yellow stains on clothing. This is especially prominent when sweat contains impurities and when deodorants contain aluminium compounds.

Aluminium compounds

Aluminium compounds are common ingredients in many deodorants as they help control sweat production. Unfortunately, the compounds can also react with sweat and the skin's natural oils, which can result in yellow stains on clothes. The higher the concentration of aluminium in the deodorant, the higher the risk of staining. Try Aluminium-free deodorant from Australian Bodycare

Detergents and stains

Detergents also play a role in the formation of yellow stains. Some detergents may contain enzymes or colourants that can interact with the chemicals already present in yellow stains. This can worsen the appearance of the stains and make them more visible on clothes. It's important to choose detergents that are gentle on the fabric and don't exacerbate the problem.

Preventing yellow stains

To avoid the formation of yellow underarm stains, it is important to apply deodorant correctly. Avoid using too much deodorant, as excess product can react with sweat and result in stains on clothing. It is recommended to let the deodorant dry completely before getting dressed.

Dryers and heating

High heat from tumble dryers can exacerbate the problem of yellow stains. Heat from tumble dryers can cause the chemical compounds in sweat and deodorant to penetrate deeper into the fabric, which can lead to more visible stains. If possible, avoid using high heat in the tumble dryer and preferably let clothes air dry.

Choice of fabric and colour

Fabric choice and colour can also play a role in minimising visible yellow spots. Darker colours and patterned fabrics can help hide the stains. You may also consider wearing loose-fitting clothing, as this allows more air circulation and can minimise contact between clothing and sweat.

Choice of deodorant

To reduce the risk of yellow stains, consider using deodorants without aluminium compounds. Australian Bodycare offers a Deo Creme and a Deo Spray that are free of aluminium. The products contain natural ingredients such as Tea Tree Oil to control sweat odour, and as they are completely aluminium-free, you minimise the risk of staining your clothes.

Prevention and maintenance of clothing

Hygiene habits

To minimise the risk of yellow stains under your arms, good hygiene habits are important. Wash your armpits thoroughly and use a mild but effective soap. We recommend Australian Bodycare's Tea Tree Oil Body Wash to remove sweat that can react with deodorant and cause staining. Tea Tree Oil Body Wash has natural cleansing properties that can help keep your skin clean and fresh.

Storage and care

Proper storage and care of your clothes can also help prevent yellow stains. Avoid leaving sweaty clothes together in a closed laundry basket for long periods of time, as this can create a moist and bacteria-filled environment that favours stain formation. Hang your clothes up after use and avoid folding them until they are completely dry after washing.
