Repairing Mechanical Switched Keyboard

My Black Widow Razer mechanical switched keyboard got a stuck B key.

I needed to press hard to register the B key.

I searched through the internet for ways to repair these mechanical switches.

Many of them require that we dismantle the switches and clean the parts with ethanol.

I tried to clean my B switch by immersing it with 95% surgical ethanol three times while pushing the switches vigorously.

It worked. No need to dismantle the switch.

It is a lesson to us how to repair mechanical switches. Membrane switches are different. Ethanol may dissolve the membrane.
