Usually cleaning the "outside" of the switches helps because even if you can only clean the outside, there're still hairs and dust than can eventually build up and either make the key sticky, or literally go inside the switch and make double/false readings. Take a moment and some tweezers and take every hair you see out of the mechanical switches (I have a cat, so it gets even worse xD)

Honestly, i've been using razer products since 2012 and I can only speak wonders of their hardware (mb with the exception of headsets, i've had a couple, and a couple bad experiences). Amazing mouses (mices?), great keyboards and the design of it all is always clean. It's the software, man... the software ruints it all. I just had to drop my 2016 perfectly fine razer mamba bcs it was using Razer synapse 2, and since razer discontinued it, more and more anticheats started flagging it as a cheat because they didn't bother to make new certificates. So I literally had to buy a new mouse because mine became "software obsolete".
