Podcast Summary: Hyperfixed – "The Pits" (Released December 4, 2025)
Main Theme
This episode of Hyperfixed dives deep into an all-too-common and quietly infuriating household mystery: armpit stains. Whether a superficial nuisance or a chronic wardrobe wrecker, Alex Goldman investigates why some people suffer from perpetual pit stains (despite all best efforts) and what, if anything, can be done to overcome this "first-world problem." Through candid conversation, scientific inquiry, and gritty laundry tips, Alex tries to bring peace to the shirt-destroyed soul of listener Heath.

Detailed Breakdown
1. Setting the Scene: Heath’s Laundry Agony
[04:48 – 10:10]
- Who’s Affected? Heath, a TV/film director in LA and, notably, the husband of Hyperfixed producer Emma Cortland.
- Heath’s issue: No matter what deodorant he uses, how he showers, or how he launders, his shirts develop persistent armpit stains—yellow, dark, oily—ruining his wardrobe.
- Regular cleaning products and DIY pastes barely make a dent.
- Quote, Heath:
“It seems like dead skin... you could probably get a DNA sample of me off of a 12-year-old shirt that’s been washed hundreds of times.” ([08:41])
- Old shirts' armpit stains might even be “load bearing” at this point.
[10:31]
- His question: Is it him, the products, or laundry failings? Why do his shirts suffer more than others’?
2. Science Corner: Dr. Armpit Explains All
[12:11 – 17:41]
- Guest expert: Dr. Chris Callewaert (aka "Dr. Armpit"), Belgium-based microbiologist specializing in underarm bacteria.
- Personal turning point: Dr. Armpit got into the field after a one-night stand left him with sudden, persistent body odor—eventually discovering body odor is "contagious", as it’s due to colonies of particular bacteria passed between people.
- Quote, Dr. Armpit:
“Body odor is contagious? – Yes, absolutely.” ([15:27])
- Relevance to stains: Sweat isn’t all the same. There are two sweat glands:
- Eccrine: Produces watery, cooling sweat
- Apocrine: “Super sweat,” triggered by cortisol/stress hormones; fatty, protein-rich, delicious to bacteria, and most likely to stain shirts
- Theory: Heath likely produces more cortisol-driven (apocrine) sweat than most—maybe genes, maybe lifestyle. This makes him more susceptible to intractable pit stains.
- This is not a fixable mystery without an expensive biological investigation.
Notable Moments:
- Alex: “Body odor has nothing to do with the smell of your sweat… It’s the bacteria.” ([14:28], [14:36])
- Evolutionary tidbit: The greasy sweat in animals helps slip away from predators.
3. Extreme Laundry: Tips from a Professional
[23:07 – 29:51]
-
Expert: Joe Cuomo, Director of Equipment & Travel for the Brooklyn Nets.
-
Stain removal realities:
- The dryer is a shirt’s worst enemy for stains. Once dried, stains often become permanent.
- Best shot at removal: Hot water soak with cleaning solution, agitate every 30 minutes, then rewash. Mixed success depending on fabric and stain.
- Commandments of Laundry:
- Wash promptly (don’t let sweat sit).
- Avoid the dryer whenever possible.
- Try multiple solutions:
- Baking soda + water paste (gently scrub)
- White vinegar
- Hydrogen peroxide
- Dish detergent for grease/grime
- Oxygen-based bleach for stubborn stains
Quote, Joe:
“The first commandment of washing: wash promptly... Number two, avoid the dryer when possible.” ([28:14])
4. Resolution: Sharing Truths with Heath
[30:50 – End]
- Emma delivers the verdict (substituting for flu-ridden Alex):
- Bad news: Old pit-stained shirts are likely lost causes, especially if they’ve been through the dryer.
- Good news: The issue isn’t everyday sweat, but is triggered by stress/cortisol. Days of big emotions (sports games, Fortnite finales, etc.) are super sweat days.
- Action plan:
- Prioritize laundry on “big emotion” days.
- Never let post-sweat shirts sit—wash ASAP, never more than three days.
- Air dry, not machine dry, to avoid setting future stains.
- For those determined, medical options exist (armpit Botox; sweat gland removal), but Heath declines (“There’s no way I’m gonna botox my armpits…” -[34:17]).
- Reflection: Heath realizes his gym shirts (used for exercise) stay stain-free, while “nervous sweat” shirts (Fortnite, football games) suffer worst.
Humorous Highlights:
- “I now have nervous sweat just thinking about surgery.” (Heath, [34:58])
- “Best solution? Buy more shirts.” (Heath, [34:48])

“The first commandment of washing: wash promptly... Number two, avoid the dryer when possible.” - Heath ([34:48]):
“Now I’m sweating. I now have nervous sweat just thinking about surgery.” - Alex ([14:36]):
“Body odor has nothing to do with the smell of your sweat… It’s the bacteria.”
Conclusions & Takeaways
- Pit stains are mostly a product of stress-related (apocrine) sweat and its symbiotic bacteria—not just the antiperspirant you use.
- Speed is everything in laundry. The longer a sweaty shirt sits (especially one that's emotionally "charged"), the more likely stains stay.
- Once dried, especially by machine, stains are nearly impossible to remove.
- There are extreme medical options, but most people will want to adjust habits, not their armpits.
- Even experts have limits. For shirts repeatedly destroyed by stress, sometimes the solution is acceptance, not just science.
Hyperfixed combines humor, expertise, and real-life frustration to untangle everyday annoyances. While not all problems are fully fixable, Alex and Emma offer listeners a mix of knowledge, commiseration, and practical hacks—a balm for both the stain-afflicted and the simply curious.
