I’ve got a Garmin vívoactive 4 that I’ve been using almost daily for the last 3 years. Recently it’s started causing some irritations on my wrist (slight redness and dry skin). I’m assuming that it needs a really good clean but I’m not sure what’s the best. Dish soap and warm water? Or is there something better?
I think dish soap is a great start. It’s mild and doesn’t have abrasives or harsh chemicals that may stain the watch. I have a Mk2i and that’s how I’ve cleaned mine when it needed it.
You may also have developed a mild allergy to whatever the back of your watch is made of, in which case cleaning won’t help.
