Garmin HRM Pro Plus strong offensive odor emanating from the chest strap

Hello fellow Garminians,

I have an issue with the Garmin HRM Pro Plus chest strap. After about 3 months of regular use (running), it starts to smell bad, like really bad to the point where its nauseating. I follow the care instructions to the T, rise after every use, hand wash weekly with mild detergent, rinse, hang to dry. The odor is unique in that it smells like something of a burnt electronic? Not sure exactly how to describe the smell but very pungent and fills the room and sticks to my clothes and skin. At first, I thought it was leaking something internally, Garmin kindly replaced the original unit, however the exact same issue has developed again with a new unit after 3 months of use.

I am wondering if anyone else experiences this. Is there a better way to clean it? Do all chest straps smell like this? Is it me?

I do enjoy using the unit for HR accuracy, but the smell is too much and I don't want to replace it again for a 3rd time only to have the same thing happen.

    I contacted the french Garmin customer service by email with link to this forum. They asked me to return the belt to replace it with another one. So don't waste your time trying to wash it. it's not normal that such an expensive product has this problem. In addition, we don't know if there can be a health risk with this plastic in contact with the skin.

    I therefore invite you all to contact Garmin to return your belt.

    Hi, I tried this product even on other clothes with no problem, apparently. Anyway, it's quite concentrated, so don't shoot too much ;) otherwise it'll stay there even after rinsing.

    I keep investigating about the possible skin reaction, anyway.

    Cheers.

    Thank you for being a test subject :-) 

    Anyway, it's good news that we finally found a potential solution. The main issue with everything I've found to be working so far is that the smell reappears after the first run.

    Thought I was going crazy.  Same issue, this is a defective product and probably dangerous.

    I've thought of this as well, the chemicals being released might trigger potential health issues in the long term, which I presume can't ever be traced back.

    I had the same experience talking with Garmin support in North America. The representative told me that they wouldn't expect this issue to persist, and that any odor should be minor and dissipate over time. Their explanation was actually that it would be the rubber gasket given off some odor, but that's definitely not the case for me. It smells strongly like cat urine, and it's only getting worse even when diligently following the care instructions. They also suggested a replacement.

    Given that this is my second Garmin heart rate strap with this issue, I'm not confident that it's going to be different with the third strap but I guess we shall see. The two straps I had the issue with were the HRM Pro and now the HRM Pro Plus.

    Garmin straps aren't the only ones that can get stinky.

    My Polar H10 strap after 8 weeks and 40 activities was fine until I washed it, hung it to dry and picked it up again after a week of *not* using it. The familiar mixture of lysol/blown electrolytic capacitor/horse stable smell emanated from it just as bad as my HRM-Tri. I had followed Polar's care instructions to the letter. Leaving it hanging on a drying rack for a week seems to have brought it on. If that is improper use, both Polar and Garmin should update their care instructions. "Use it every day or else the strap gets mad at you, and will vent its anger through smell! Take it with you on each and every multi-day trip or it gets lonely and will call for a mate by exuding powerful pheromones!"

    Edit: Most cheap replacement straps do not work with the H10, the contacts are too far recessed on the module.

    Leads me to think that both manufacturers are likely using the same components. 

    From my observations, I'm presuming that what smells so bad are the rubbery conductors inside the strap, on each side of the sensor in the front. That's where most of the smell is present in my straps. 

    I've been experimenting with more and more detergents and the smell still reoccurrs. The last ones tried are Sanytol disinfecting detergent and balm, I've soaked the strap in each after washing it with Marseille soap. The smell substantially disappeared but came back after a couple of wears.
