Safe way to remove limescale on Fenix 8 near microphone and barometric ports?

Hello,

My Fenix 8 has a white, chalk like film on the bezel edges and in small seams.
I believe it is limescale from sweat and hard water. There is also residue near the microphone and barometric port.
I routinely rinse with fresh water and use mild soap with a soft brush, followed by a microfiber wipe.
I have avoided vinegar or citric acid because I am unsure if they are safe for the watch’s coatings, gaskets, adhesives, microphone, and barometric sensor. I would appreciate official guidance or community experience on a safe cleaning approach and any products that are considered acceptable. I would also like to know what to avoid and how to clean close to the ports without pushing debris inside.
Thank you.

    I had to exchange a Fenix 8 through the service because the microphone did. I believe it was caused also by limescale.
    The new one I always rinse off when washing hands, showering etc. Afterwards i shake it out, try it with the towel and always use the water push out function. If it helps I don’t know.

    È molto importante sciacquare con acqua dolce  il dispositivo dopo l'allenamento ,un bagno in mare o piscina o quando si suda per prevenire le problematiche che hai appena citato. C'è l'ho da quasi 6 mesi e non presenta nulla.

    Citric acid might be safe to use externally using a toothbrush on affected areas, for aesthetic purposes. You can mix with dishwashing liquid for retention. As far as I know there's no aluminium or copper on the outside of the watch, which are two metals that might corrode depending on the concentration. Gloves are required since it attacks skin. 

    Regarding ports - they are so small that I doubt there's any way to "micro clean" them without pushing something inside. 

    I guess the keyword here is prevention. As one user says, it's a good idea to rinse the watch with distilled water after every hard activity, as the limescale is not "set in" yet and might dissolve in the pure water easier than in tap water.
