Push button cleaning

[acropora]

Hi OSTC community,

Would you have any recommandation about cleaning procedure notably
for the push button on the OSTC3 ?

The buttons are pretty much encapsulated inside the case, but appart from a warm fresh water rinse what do you use/recommend ?
Water jet between the gap ?
Any advice on a way to put the button apart or have a back access ?

Thanks for your help and the good work you do !
