Keyboard Chatter

I've had the same keyboard chatter issue with two different keyboards from two different brands. I know the issue is with the keyboards because it persists between different computers.

Am I just unlucky with the hardware I got? I don't want to invest even more money into a third mechanical keyboard if the issue is really that common.

Anyone have tips for dealing with keyboard chatter? Can I clean the switches or something? I don't have a switch removal tool.

The current mechanical keyboard I have is a Corsair K70 RGB Core that's just sitting in my closet.

I've tried software solutions to mitigate the chatter, but it's kind of clunky and doesn't run until after I login once.
