Ah, the inevitable set-in pit stains. A topic I have not written about in a long while.
Before we talk about how to make your own underarm stain remover at home, let’s clarify what we’re talking about.
Deodorant Marks vs. Pit Stains (Yellow) vs. Deodorant Buildup vs. Pit Stains (Sweat)
Let’s get one thing clear right off the bat, there is a big difference between deodorant marks, pit stains and deodorant buildup.
Those white streaks you get on the outside of your shirts as you’re sliding the shirt down past your deodorant/antiperspirant-coated armpits.
I’ve personally experienced this mostly when using some form of stick antiperspirant or deodorant, but it’s possible that it’ll also occur if you use spray or roll-on solutions.
Keep in mind that you can get “deodorant marks” (white streaks) on your clothes if you’re using deodorant or antiperspirant.
FACT: Antiperspirant is for sweat prevention and most antiperspirants also have odor prevention. Deodorant has odor prevention only.
Pit Stains (Yellow)
Those set-in stains that occur primarily as a result of using antiperspirant.
The aluminum content in the antiperspirant combined with residual underarm sweat can transfer to the underarm area of the shirt, and over time, yellowish or brownish stains can begin to appear.
These stains can even harden over time and regular laundering or bleaching will not remove them. In fact, bleaching them can make them worse.
That thick, caked-on residue that forms on the pit area of your shirts over time.
It’s usually a result of using stick antiperspirant or deodorant. The wax-like substance of these solutions will transfer to the shirt during the day, and won’t fully wash out while laundering.
Repeat this a bunch of times, and eventually you’ll have a gooey, cakey, waxy buildup in the pit-area of your shirts.
Pit Stains (Sweat)
The term “pit stains” is also widely used to refer to the sweat stains that show up on the underarm area of someone’s shirt who is sweating a lot.
There’s really no need to address this particular issue, since it’s really just wetness showing through on the pits of your shirts, that will dry once you cool down.
Removing Deodorant Marks
Removing deodorant marks is pretty simple actually. In fact, there are easily thousands of articles out on web that provide ideas on how to quickly remove those white streak deodorant marks from your shirt.
The most common recommendations to remove deodorant marks from your shirts are to:
- Rub another part of your shirt on the mark
- Take a nylon stocking or cotton sock and rub it on the mark
- Used fabric softener sheets
- Find a piece of foam rubber, like that grippy foam on the top of hangers, and rub that on the mark
Here’s a video showing a good example of how to remove white deodorant marks from a black shirt using a used fabric softener sheet and a sock.
Removing Pit Stains (Yellow) & Deodorant Buildup
Although still generally referred to in the public domain as “removing deodorant stains”, there are just as many, if not more articles out there claiming easy at-home solutions for removing pit stains and deodorant build-up.
The most common recommendations are using things like ammonia/water, baking soda/peroxide/dishsoap, lemon juice, meat tenderizer, etc.
While those concoctions may work on some minor stains, they are simply NOT effective most of the time.
In other words, don’t waste your time trying them. See the Pit Stain Problem youtube channel where the folks tested a bunch of these solutions.
I wrote an article about Removing Deodorant Stains back in 2008, keeping it fairly up-to-date over the years.
It’s had nearly 200,000 views, and there have been ONLY THREE solutions that people will say effectively remove either pit stains, deodorant buildup, or both (aka “deodorant stains”). They are:
- Deo-Go Underarm Stain Remover. I tested it and it worked
- Raise Pit Stain Remover
- OxiClean (overnight soak is most effective)
Make Your Own Effective Pit Stain & Deodorant Buildup Remover
A reader wrote in recently and shared with me his own DIY underarm stain remover solution, that has a similar ingredients to Deo-Go:
Just wanted to share some DIY tips. I love Deo-Go, and it really works, but the small size of the bottle, the price, and the fact that you have to order it online were a bummer for me.
After doing some research (their patent is online) I learned that the key ingredients are a strong mineral acid and surfactant. I tried several combos like CLR and Dawn with no result.
But, I have found a much, much cheaper solution that works 90% as well as Deo-Go:
50% Lime-a-way, 40% water, 10% Tide Free and Clear
[Note from Tug: Tide makes “Free & Gentle” and All makes “Free & Clear”]
The Tide was the best surfactant and seemed to be the most color safe because it does not contain oxy, bleach or brighteners – it also rinses the cleanest.
Saturate both sides of fabric with solution and rub with brush. Let’s sit for 20 minutes and you will see the residue soften (I was actually able to squeeze some out of seam like toothpaste. Yuck!). Spray both sides again and likely scrub, and then wash as usual.
Worked on some pretty serious gunk. Definitely wear gloves and use in a well-ventilated area.
What a great find and thanks to Michel for sending in his at-home pit stain / deodorant buildup solution!
I have not personally tried this yet, but I have a feeling it’ll work, based on the research Michel did.
If you give it a go, be sure to let me know how the Lime-a-way / Water / Tide mixture works for you — either in the comments section below, or send me note.
Krud Kutter To Remove Deodorant Stains
Got this update from CLS (who commented below) who tried using Krud Kutter to remove deodorant stains from her husband’s shirts:
Just wanted to give an update but couldn’t post a picture to go along with it.
My comment stated that I was going to try the Lime-a-way mixture but I’ve been to 3 local stores and none of them have that specific lime a way.
I could only find the spray cleaner that’s not as concentrated.
I have a few more stores to check locally before ordering it online.
However, one of the readers comments on that page stated they used the Krud Kutter.
My hubby happened to have some this Krud Kutter (link) in the garage, so I thought why not give it a shot.
While there is some very very slight residue left on the shirts, I’m very happy with the results.
I did not scrub them together, I did not brush them, simply sprayed them, left sit for about 10 mins before tossing in the washer.
My plans are to keep a spray bottle of this next to my washer and give them all a spray prior to tossing in the machine, hopefully all residue will be gone after a few washes.
Or I may give them all a good scrubbing with a brush and soak them a little longer (but he’s due for new work shirts at the end of the month, so I wasn’t feeling that adventurous or is that energetic?) :-)
I wished Deo-Go wasn’t so expensive, but I may have to give it a shot on my sons favorite old T-shirts.
Thanks for the informative page!
PS. If I do the lime a way I’ll definitely let you know how it goes.
Great info from CLS!
Be sure to read through all the comments too, because lots of folks have shared their deodorant stain removal attempt results.
So, to summarize, the list of possible REAL solutions to remove deodorant pit stains from shirts are:
- Lime-a-way mixture
- Krud Kutter
- Deo-Go or Raise
- Oxi-Clean (may not address deep, set-in stains)
