Barometric sensor cleaning

[Mattg576]

I’ve recently been getting altitude values that are way off reality with my Suunto Race, it’s always been pretty spot on so have never thought about the sensor needing a clean.

On close up examination using the magnifier app on my phone it appeared to have some crap in there so have been attempting to clean it (submerging the watch in water with a drop of washing up liquid for an hour or so then rinsing under a slow running tap) & I seem to have cleared most of it but the readings are still off.

I’m currently sat at home which is 165ft above sea level & it says I’m at 414ft (but the graph shows minus values).

Would someone with a Race 1 that gives good altitude readings (and a clean sensor) share a close up pic so I can see if my cleaning is going in the right direction please

I bought the watch in January 2024 so has just come out of warranty #justmyluck

Many thanks

@Mattg576 What is the pressure reading and does that match with the weather stations around you? Maybe the altitude is off because of the water pressure.

@Mattg576 don’t know if it helps, but mine works and looks like this

There seem to be small „slits“ on the black inside
