What Causes Armpit Stains

Armpit stains are due to the deodorants and antiperspirants that are used every day. The residues from these, combined with sweat are transferred on to whatever you are wearing. Over time, these deposits build up and cause your clothing to look discoloured and permanently stained.

The main offending chemicals are either aluminium chlorohydrate, or aluminium zirconium tetrachlorohydrate gly. These are the most common active ingredients used in most of the antiperspirants and some of the deodorants on the market today. In simple terms, these chemicals block the sweat glands, preventing perspiration. However, if perspiration occurs after application of a product containing either of these chemicals, then the sweat combined with the chemical residue can be absorbed by the fabric in the armpit area of the clothing, leaving deposits.

Over time, these deposits can build up, forming stiff or waxy patches and staining clothing. On light coloured clothes, the stains tend to be yellow or brown in colour, and on dark clothing, the stains tend to have a faded or bleached appearance.

These stains won’t come out in a normal wash cycle, and boiling, heat exposure and bleaching actually makes them worse! This is where Deo-Go comes in.

Although your clothing may appear to be bleached, faded or stained beyond the point of revival, this is not the case….Deo-Go will save it!

Other Stain Removal Methods Don’t Work

There are many household cleaning agents and some slightly more unorthodox methods, as suggested on many of the online advice websites and discussion forums. These are some of the more talked about ones we have tried:

  • Proprietary stain removing, cleaning and laundry pre-treatment products such as Vanish, Shout, Tide, Stain Devils and Glow-white etc.
  • Bleach – Many people recommend the use of bleach, hydrogen peroxide or ammonia for deodorant stain removal. However, bleach reacts with the deposits and turns the stain even darker.
  • Baking soda (sodium bicarbonate) or a mix of baking soda, water and peroxide – These are regarded by many as one of the most effective ways for removing deodorant, antiperspirant and sweat stains.
  • A paste of aspirin, cream of tartar and water.
  • Lemon juice.
  • Vodka.
  • Vinegar.
  • White spirits.
  • Toothpaste.
  • Leaving a stain to dry in direct sunlight.

Extensive testing has shown us that none of the above suggestions are even close to effective.

Deo-Go is the only product or method of cleaning a shirt that is 100% effective at removing deodorant and antiperspirant stains.

Preventing Future Stains

Here are some tips for reducing deodorant / antiperspirant stains on your clothes:

  • Undershirts, this will stop staining on your outer shirt, but not the undershirt.
  • Sweat pads.
  • Before putting on your shirt, let your armpits fully dry after deodorant/antiperspirant application.
  • Avoid applying an excessive amount of antiperspirant.
  • Try using aluminium free or low aluminium antiperspirant or deodorant, these can reduce or even eliminate the residue build-up and the associated staining. There are now antiperspirants on the market which claim to reduce yellow staining.
  • Regular use of propriety stain treatments on the armpit of your clothing may reduce the amount of build up.
  • Don’t tumble dry or iron the armpit area of the clothing if you suspect it has any residue on it, heat can enhance the visibility of the stain.

Don’t despair if you do get these stains, use Deo-Go and your shirt will be as good as new!
