How Baking Soda Made My Commute and Laundry Easier

My commute became simpler, laundry felt less fraught and, most unexpectedly, my friends noticed-in the nicest possible way.

It began on a sweltering afternoon, with buses creeping along, when my dependable “48-hour” stick gave up after just four hours. As I packed into a crowded lift, I hoped desperately that nobody would raise an eyebrow. That evening, I opened the cupboard, tipped a barely-there amount of baking soda into my hand and swept it on with a soft brush, as though I were applying make-up rather than changing a routine. The following day, I did not smell “nice” - I smelled of nothing, which somehow meant everything. She moved closer, sniffed and blinked.

The kitchen solution that beat my expensive spray

By the third day, the real surprise was not simply that I remained fresh on a muggy Underground journey. It was how unobtrusive the result was: no citrus blast, no powdery haze and no floral clash with my perfume. Yes, ordinary baking soda. The same box that stops the fridge smelling odd neutralised the sour shift on my skin that would usually appear around lunchtime. My shirts made it through lengthy meetings. Hugs at 6 p.m. felt entirely ordinary. I had not stopped sweating; my body had simply stopped announcing it.

For a week, I followed a ridiculously basic routine: apply it in the morning, do a sniff test at midday, carry out an honest evening check, then repeat. One Thursday, fuelled by coffee, I cycled to a friend’s home, locked up my bike and waited for the potentially awkward “you okay?” message afterwards. Nothing arrived, so after we had made dinner, I asked her outright. She laughed and said, “You smell like… no scent at all,” which feels like the kindest possible compliment when you live in a city made of humidity and hope. For once, the effect was not perfumed; it was subtle.

There is a wonderfully straightforward explanation. Sweat itself has no smell; odour begins when bacteria on the skin break it down and produce those sharp compounds. Baking soda is particularly effective at neutralising the acids involved in that change. By increasing the pH at the skin’s surface and giving odour molecules something to react with, it disrupts the whole scent process before it takes hold. Antiperspirants rely on aluminium salts to block sweat glands, whereas deodorants conceal or neutralise odour. This belongs to the latter group, reduced to its most basic ingredient. It didn’t fight my body; it edited the script.

How I use baking soda, step by step

My approach could hardly be more low-tech. After a shower, I dry myself thoroughly, then place a very small pinch of baking soda - roughly the size of the top of a pencil eraser - into my palm. I dab it over each underarm using a clean, soft brush or dry cotton pad. On hectic days, I make a pea-sized paste with a drop of water, smooth on an extremely thin layer and allow it to dry before dressing. When doing laundry, I combine two parts arrowroot or cornflour with one part baking soda; it helps the powder glide on and keeps the finish light beneath a T-shirt.

Using too much can make skin irritable, so I use the smallest amount possible and avoid freshly shaved mornings, when a raised pH combined with tiny nicks can sting. If my underarms feel sensitive, I use the blended powder instead or pause altogether, applying a small amount of fragrance-free moisturiser at night to support the skin barrier. My reliable travel trick is to transfer a tablespoon into a clean lip balm tin, apply it with my fingertips, then wash my hands. Realistically, nobody does that every day. Even so, “good enough” turns out to beat “perfect” by lunchtime.

When people ask whether it “really works,” I think of the quiet everyday benefits: clothes that last longer, no more disagreement between body odour and my cologne, and the freedom from examining every label like a detective.

“My commute became a science experiment on sweat - and I won.”

I still use a gentle, aluminium-free roll-on for travel days, but this cupboard staple handles a remarkable 80 percent of everyday life.

• Start with less than you think you need, then use even less.
• Do not apply it immediately after shaving; evening is gentler.
• On sensitive-skin days, mix it with arrowroot.
• If you are prone to reactions, patch-test it on your inner arm.
• If you apply too much, rinse with warm water - no drama required.

What changed beyond the odour

We have all experienced the point when a busy room suddenly feels like a mirror, making you intensely aware of your own skin. This small change released that feeling for me, not because I became a minimalist monk, but because it reduced the mental burden: no cloud of fragrance, fewer laundry struggles and a better understanding of what works on a normal Tuesday. It’s strange how “nothing” can feel like having more-more ease, more control, more room to breathe. I still carry a traditional stick in my bag for “big day” nerves, but my daily essential now sits beside the salt, demanding almost nothing while giving plenty in return.
