The idea of using mouthwash for anything other than oral hygiene might seem peculiar, but the internet is full of unconventional beauty and health hacks that pique curiosity. One such hack is soaking feet in mouthwash, a practice claimed to offer various benefits from improved skin texture to reduced odor. Intrigued by these claims, I decided to embark on a five-day experiment, soaking my feet daily in a concoction of blue mouthwash and warm water.
As someone who is always on the lookout for effective home remedies, I was eager to see if this simple combination could deliver noticeable results. I documented each day’s experience meticulously, observing changes in skin texture, odor, and overall foot health. Here is a detailed account of my journey, along with insights into the potential benefits and drawbacks of this foot soak treatment.

1. Why Use Mouthwash for Foot Soaking?
Mouthwash is primarily designed to kill bacteria and freshen breath, but its antiseptic properties can extend to other uses. The idea of using it for foot soaking stems from its ability to combat bacteria and fungi, which are common culprits behind foot odor and infections. A typical mouthwash contains alcohol and essential oils like thymol and eucalyptol, known for their antimicrobial effects.
By soaking feet in mouthwash daily, proponents believe that it can reduce bacterial growth, soothe skin, and even help manage conditions like athlete’s foot. The alcohol content in mouthwash, often around 20% to 30%, can help dry out excess moisture, a breeding ground for fungi, thereby contributing to foot hygiene.
2. The Ingredients in Blue Mouthwash
Blue mouthwash typically contains a mix of active ingredients designed to target oral bacteria, but these can also benefit the feet. Ingredients like ethanol (alcohol) are effective at killing a wide range of bacteria and fungi. Thymol and eucalyptol, derived from thyme and eucalyptus oils respectively, provide antifungal and antibacterial properties.
Menthol, another common ingredient, offers a cooling sensation and can help soothe irritation, while methyl salicylate provides a mild anti-inflammatory effect. This combination of ingredients makes blue mouthwash a potentially effective solution for addressing foot-related issues.
3. Preparing the Foot Soak
To prepare the foot soak, I mixed one cup of blue mouthwash with two cups of warm water in a basin large enough to comfortably fit my feet. Ensuring the water was warm was crucial, as it helps open pores and enhances the absorption of the active ingredients.
I set aside 20 minutes each day for this routine, allowing myself to relax and unwind as my feet soaked in the solution. It was important to dry my feet thoroughly afterward to prevent any residual moisture that could counteract the benefits of the soak.
4. Initial Reactions and Sensations
On the first day, the most immediate sensation was the cooling effect of menthol, which provided a refreshing feeling to my tired feet. The smell of the mouthwash was strong but not unpleasant, reminiscent of a typical dental visit.
There was a slight tingling sensation during the soak, likely due to the alcohol content, but it was not uncomfortable. After the first session, my feet felt clean and surprisingly invigorated, a promising start to the experiment.
5. Changes in Skin Texture
By the third day, I began to notice subtle changes in my skin. The soles of my feet felt softer, and some of the rough patches, particularly on my heels, appeared less pronounced. This could be attributed to the exfoliating effect of the mouthwash, as the alcohol and essential oils helped remove dead skin cells.
By the end of the five days, the overall texture of my skin was smoother, and the dry, flaky areas had diminished significantly. While not a complete transformation, the improvement was noticeable and encouraging.
6. Impact on Foot Odor
One of the most touted benefits of using mouthwash for foot soaking is its ability to combat odor. By the second day, I noticed a reduction in foot odor, likely due to the antibacterial properties of the mouthwash eliminating odor-causing bacteria.
After five days, the unpleasant smell was virtually gone. The fresh scent of the mouthwash lingered for hours after each soak, providing a pleasant aroma that lasted much longer than expected.
7. Effects on Toenail Health
While the primary focus was on skin and odor, I was curious to see if there would be any impact on my toenails. Over the course of five days, my toenails appeared slightly brighter and cleaner, possibly due to the antifungal properties of the soak.
Although the short duration of the experiment did not yield dramatic changes, the initial improvements suggested that regular use might contribute to healthier nails over time.
8. Any Relief from Foot Pain?
Although I didn’t suffer from significant foot pain, I did experience occasional soreness from long days on my feet. The soothing effect of the menthol provided temporary relief, akin to using a cooling gel or balm.
While the soak did not alleviate all discomfort, the general sensation of relaxation and the ritual of taking time to care for my feet contributed to an overall feeling of well-being.
9. Potential Risks and Side Effects
Despite the positive outcomes, there are potential risks to consider. The alcohol content in mouthwash can be drying, especially for those with sensitive skin. Overuse might lead to irritation or exacerbate dryness.
It’s also important to ensure no open cuts or wounds are present on the feet, as the mouthwash could cause stinging or further irritation. Conducting a patch test before full immersion is advisable for those with sensitive skin.
10. Comparing with Other Home Remedies
Compared to other home remedies like vinegar or Epsom salt soaks, mouthwash offers a unique combination of benefits. Vinegar is known for its acidity and antifungal properties, whereas Epsom salts are typically used for their soothing and anti-inflammatory effects.
While each remedy has its merits, the mouthwash soak provides a refreshing alternative with its potent antibacterial capabilities and pleasant scent, setting it apart from more traditional solutions.
11. Would I Recommend This Hack?
Based on my experience, I would recommend trying the mouthwash foot soak for those interested in an easy, at-home treatment to improve foot hygiene and odor. The results were promising, particularly in terms of skin texture and odor reduction.
However, it’s important to be mindful of individual skin sensitivities and to avoid overuse. As with any home remedy, what works for one person might not be as effective for another, but the mouthwash soak is certainly worth a try.
