My 6 year old Steelseries 7G some keys registering multiple input sometimes. Any advice? like opening the cherry keys & cleaning the contacts, or maybe swap the keys with some less used keys etc.

My old Ducky 9008s some keys had delay registering, so I desolder the affected switches and swapped with lesser used keys and they seem to be working . Pretty easy fix each switch has 4 points of solder 2 for the switch 2 for the LED. The LED solder was quite small & took some time to remove but with some patience can be done. Next time can try fixing my SS 7G which some keys double/triple register, should be easier since no LED to remove but don't know how the insides look yet.
