Understanding Your Garmin Watch Strap Material
Before we start diving right into the cleaning methods, it’s crucial we identify your Garmin watch strap material, as each one actually requires a slightly different approach. Garmin themselves offer a range of different types of straps, from classic silicone and nylon fabric to leather and metallic each with unique properties and differing cleaning needs.
-
Silicone Watch Straps (The Most Common): Well known for their durability and water resistance, classic silicone straps are the most popular for sport-specific use and gym workouts. However, they are more prone to trapping sweat than some of the alternatives, which can quickly cause, itchiness, smelly odours and stubborn stains.
-
Nylon Fabric Watch Straps: Lightweight, comfortable and more breathable, nylon straps are perfect for runners but are highly absorbent and can become smelly if not cleaned correctly and on a regular basis.
-
Leather Watch Straps: Classic looking, stylish and sophisticated, but leather is more delicate and can easily absorb sweat, leading to permanent stains if not treated carefully.
-
Metal Watch Straps: Metallic stainless steel or titanium straps are solid, sturdy and easy to clean but can accumulate grime in the connection links over time.

How to Clean Sweat Stains from My Garmin Strap?
Sweat stains are by far the most common on silicone and nylon straps due to the fact that users will most often opt for these materials for use during sports along with the material's absorbent nature. If you start to notice discolouration or a lingering smell on your watch band:
-
For silicone bands, scrub the material gently with a soft-bristled toothbrush and a mixed-up solution of warm water and mild soap.
-
For your nylon watch bands, soak them in lukewarm water and add a very small drop of vinegar for 15 minutes, then rinse the watch band thoroughly afterwards.
-
Always avoid harsh chemicals such as bleach, which can quickly cause damage to the strap material and fade its colour.
How to Clean Garmin Strap: A Step-by-Step Guide (With Sport-Specific Tips)
Cleaning your Garmin watch strap correctly ensures it stays looking fresh, and odour-free, and lasts much longer than if you neglected it. So, let's get to it and break down the full cleaning process by strap type, focusing in detail on silicone watch straps, as they are the most common among Garmin users. Plus, we’ll provide some sport-specific cleaning tips tailored to your own specific workouts.

🧼 For Silicone Straps (Best Choice for Triathlons, and CrossFit Athletes):
Silicone is a top choice for many athletes because of its waterproof, durable, and flexible nature. However, its reputation for easily trapping sweat and sun cream, especially after intense workouts has much truth to it. So, here’s how you should clean it properly:
A)Speedy Daily Clean (For Regular Use and Post-Gym Workouts):
-
Remove the watch strap from your Garmin Device.
-
Rinse it under lukewarm water to wash away all of the surface sweat.
-
Wipe it down with a damp microfibre cloth using a little mild soap if you need.
-
Now pat it dry with a clean towel and allow time for it to fully air-dry fully before reattaching to your smartwatch.
B) Deeper Clean (For Sweat Stains After Intense Activities):
For longer workouts, more intense workouts or events, deep cleaning is essential.
What you’ll need:
-
Some mild soap (such as baby shampoo or dish soap)
-
Baking soda (use this for tougher stains)
-
A soft-bristled toothbrush (those wooden bamboo ones are a good choice here)
-
Lukewarm water
Step-by-step instructions:
-
Soak the strap in the small bowl of warm, soapy water for at least 5 minutes.
-
Use the toothbrush to scrub gently, focusing on creases and holes where sweat tends to build up.
-
For more stubborn sweat stains, form a paste with baking soda and water, apply it to stained areas, and let it sit there for 5 minutes.
-
Now rinse thoroughly under the lukewarm water.
-
Allow the watch band to air dry fully before you clip it back onto your device.

🏊♂️ Sport-Specific Silicone Strap Cleaning Tips:
-
After Triathlon Training (Swimming, Cycling, Running): Rinse down your band immediately so you can quickly remove any unwanted chlorine or saltwater from the surface. Salt crystals can quickly form in crevices, causing discomfort during later use and strap damage.
-
After Long Road Cycling Sessions: Sweat particles and bits of leftover suncream are common culprits here. Use a baking soda paste, as we mentioned above, to remove the sweat stains fully, and grab yourself a damp cloth to wipe off all of the sticky leftover suncream residues.
-
After Heavy Strength Training or HIIT: Weightlifting often quickly leads to sweaty watch straps with the added unpleasant odour. Add a drop of vinegar to the cleaning solution in order to kill the bacteria and remove the smell.
🧽 For Nylon Fabric Watch Straps (Popular for Runners and Outdoor Adventures):
-
Soak the Nylon band in lukewarm water along with a mild detergent and a small drop of vinegar for at least 15 minutes.
-
Use your soft-bristled toothbrush again for some gentle scrubbing.
-
Rinse the nylon band down well and allow it to fully air dry before clipping back onto your device.
🪙 For Metallic Watch Straps (Best for Everyday Wear and or more casual sports):
-
Use warm, soapy water and a soft-bristled again toothbrush to clean the nooks and crannies between the links.
-
Dry the metal band down thoroughly using your clean microfibre cloth.
🧴 For Leather Watch Straps (Perfect for Formal or Work Settings):
-
Wipe the leather band down fully with a clean damp cloth.
-
Be sure to spot-clean all of the sweat stains using a white vinegar and water mix.
-
Allow to fully air dry before clipping back onto your Garmin.
⚠️ Quick Tip for All Watch Strap Materials:
I know we touched on this above but Fitstraps always fully recommends letting your watch straps fully air-dry before you clip them back on, as wearing them when still damp can lead to the dreaded Garmin watch strap rash. So, avoid skin irritation and give your strap time to dry before you attach it back on.

The Most Common Mistakes to Avoid When Cleaning Your Garmin Strap
Even with the very best of intentions, so many Garmin watch users unknowingly cause damage to their watch straps by opting for incorrect cleaning methods. Make sure that you avoid these common watch strap rookie mistakes to keep your strap in tip-top condition:
🚫 1. Using Harsh Chemicals (Such as Bleach or Alcohol Rubs)
Overly strong cleaning agents such as bleach or an alcohol rub are too aggressive and will weaken strap materials very quickly, cause fading, and cause cracking.
Your Solution: Keep with mild soap, warm water, and soft-bristled toothbrush brushes. For sweat stains on classic silicone straps, a simple baking soda paste will be more than enough to do the job!
💦 2. Rinsing Leather Watch Straps in Water
Leather watch bands and water are not a good combination. When it comes to leather moisture will cause the leather to crack and discolour quicker than anything.
Your Solution: Wipe leather straps with a slightly damp cloth and use a tiny amount of leather conditioner. If you notice some sweat stains starting to build up anywhere, spot-clean with a vinegar-water mix and allow the watch band to fully air-dry naturally.
⚠️ 3. Scrubbing Down the Watch Band Too Aggressively
Scrubbing too hard using a hard-bristle brush can easily scratch silicone, tear apart nylon fibres, or scuff up the surface of leather watch bands.
Your Solution: Opt for soft-bristled toothbrushes or a microfibre cloth. For nylon fabric straps, give them a gentle soak with light agitation from the brush will be more than enough to remove any little bits of dirt.
☀️ 4. Drying Straps in Direct Sunlight or with Heat
Yes, we get it, now your strap is clean it needs to be back on your wrist ASAP, however rapid drying with heat such as a hairdryer, laying in direct sunlight or on a radiator can shrivell and warp silicone bands quickly put cracks in leather ones.
Your Solution: Allow time to fully air-dry your Garmin strap in a shaded area, laying it flat on top of a clean towel. This is where you can use your watch strap collection to yoru advantage by clipping on your spare strap as that one dries fully.
⛔ 5. Turning a Blind Eye to Sweat Stains
As we know, sweat stains on straps don’t just look nasty but are also a breeding ground for bacteria, which can cause skin irritation around your wrist.
Your Solution: Clean your watch strap immediately after any intense workouts or events. Use a vinegar solution for woven nylon straps and a mixture of baking soda paste for classic silicone straps to break down sweat residue before it gets lodged on there too thickly.
