Logitech g810

I bought the Logitech keyboard g810 1.5 years ago,now the buttons were double to triplicate,save you cleaning your keyboard?if Yes-that as is better.I know that full of guides and videos on the Internet-some even have already seen a glimpse,but there is some suggest buttons cleaned with hydrogen peroxide,others only in a basin with soap and water to dip,and many resonant moments.
