Irish Spring soap has a scent so strong and signature, it’s instantly recognizable. But this soap bar does more than get you squeaky clean. It has an unusual side hustle—repelling pests, freshening closets, even helping with fishing. While it might sound strange, the soap’s strong fragrance and dense formula make it perfect for all sorts of hacks around the house and garden. If you’ve got a few bars sitting around, don’t just keep them in the shower. Put them to work in surprising, practical ways.
1. Keep Mice Out of Your Home
Rodents may love cozy places, but they absolutely hate the scent of Irish Spring. That crisp, overwhelming smell is a natural deterrent, making it a budget-friendly way to keep critters away from your pantry, garage, or basement. To use it, cut the bar into smaller chunks and place them in breathable pouches—like old socks, coffee filters, or mesh bags. Then place them near suspected entry points: behind appliances, in corners, inside cupboards, and along baseboards. Mice typically steer clear of anything with a strong odor, and Irish Spring delivers that in spades. Be sure to replace the soap every 4–6 weeks as the smell fades. While this isn’t a substitute for sealing cracks and holes, it’s a surprisingly effective line of defence—especially when paired with other preventative measures.
2. Deter Garden Pests from Eating Plants
If your garden is getting picked apart by deer, rabbits, or even squirrels, Irish Spring can help. The same pungent smell that drives away mice also repels outdoor pests. It’s a safer, chemical-free solution that protects plants without harming animals. Use a cheese grater or knife to shave the soap into small bits. Stuff the shavings into small breathable pouches and hang them on tree branches, garden posts, or near flowerbeds. You can also scatter the pieces around the soil, but keep them dry and out of reach of pets. This method works especially well in the spring and summer months when animals are more active. Just remember to replace the soap after a rainstorm or once the scent fades. It’s a low-cost trick that can save your flowers and vegetables from becoming a snack.
3. Deodorize Gym Bags and Shoes
Let’s be real—gym bags and shoes can smell awful after just a few uses. Even after a wash, some odors cling stubbornly to fabric and leather. That’s where Irish Spring comes in. Thanks to its strong scent, it works as a powerful deodorizer in tight, sweaty spaces. To use it, cut a bar in half or into chunks. Wrap the pieces in a cloth or drop them directly into gym bags, sports gear, work boots, or sneakers. Within hours, the smell improves noticeably. Leave the soap overnight for best results. You can also keep a bar inside your gym locker to prevent lingering odors from settling in. It’s like a mini air freshener that doesn’t cost you a thing—and unlike sprays, it doesn’t just mask the smell; it soaks it up.
4. Freshen Up Drawers and Closets
Skip pricey drawer sachets and fancy closet sprays. A bar of Irish Spring can freshen clothes, linens, and storage bins just as well—if not better. It’s particularly useful in musty areas where airflow is limited. Just slice up a bar into pieces and wrap each one in thin cloth, mesh, or even a paper towel. Then place them in your dresser drawers, storage tubs, or the corners of your closet. The soap gives off a fresh, clean scent that lingers on clothes and keeps moths and bugs at bay. You can even tape a piece inside a closet or hang it on a hanger if you’re tight on space. Replace the soap every few months or when the scent wears off. Your sweaters will thank you.

5. Prevent Foggy Mirrors in the Bathroom
There’s nothing more annoying than stepping out of a steamy shower only to face a completely fogged-up mirror. Instead of wiping it down with a towel (and leaving streaks), try using Irish Spring to keep the glass clear from the start. Rub a dry bar of soap directly onto the mirror’s surface, covering it with a light layer. Then, buff it off gently using a soft, clean cloth until the glass is clear again. The soap leaves a thin, invisible film that prevents condensation from sticking. This method lasts several days before needing to be repeated. It’s ideal for households with multiple people sharing a bathroom—especially during winter or in places with poor ventilation.
6. Lubricate Sticky Zippers and Drawers
Soap isn’t just for cleaning—it’s also a fantastic lubricant. That’s right: Irish Spring can help you fix annoying, stuck zippers and squeaky drawers in seconds. To fix a stubborn zipper, just rub a dry bar of soap along the teeth. Open and close the zipper a few times, and you’ll notice it gliding more smoothly. For wooden drawers that stick, run the soap along the runners or sides where the wood rubs together. It’s an old-school trick that really works—no need for oil or sprays. Keep a bar in your toolbox or craft drawer for these small but satisfying fixes.
7. Use It as a Fishing Bait Enhancer
This one might sound like a stretch, but plenty of old-school anglers swear by it. Irish Spring soap has a scent that oddly attracts catfish and certain freshwater species, making it a quirky fishing companion. There are two ways to use it: rub some of the soap onto your bait or fishing line, or drop a sliver into the water near your lure. Some even embed small chunks into bait balls. The exact science isn’t clear, but anecdotal success has turned it into a low-budget trick used in rivers and lakes. Even if you’re skeptical, it’s worth trying on your next fishing trip—especially if you’ve already got a few spare bars lying around.
8. Protect Car Interiors from Musty Odors
Cars can start to smell strange if they’re parked for a while or get damp from rain and humidity. Irish Spring makes a solid, natural car freshener. It’s especially great for RVs, vintage cars, or seasonal vehicles that sit unused for months. Place a full bar (or two) under the seat or in the glove compartment. As it releases its scent, it helps mask musty odors and keeps the interior smelling fresh. It also absorbs moisture, making it a handy anti-mildew solution. For a more discreet method, tuck the soap into a small cloth pouch or wrap it in breathable paper. Replace it every couple of months for consistent freshness.
Final Thought
From your closet to your garden to the back seat of your car, Irish Spring is pulling double—no, triple—duty. These creative uses prove that this humble soap bar is more than a hygiene product. It’s a home hack essential. With just a few cuts and clever placements, you can turn a single bar into a multi-purpose tool that freshens, repels, and fixes. So next time you buy Irish Spring, grab a few extras. You’ll be surprised how many ways you’ll end up using them.
