Question Keyboard Switch

[cediegamotin]

Some of my keyboard switches does not register sometimes, I already blow it and half press, it would work but would come back again.
Can I use a 70% alcohol to clean directly the switches?

It's okay to stain my keyboard since its only generic and will buy soon. Thanks!

Sure you can try it, but I'd buy a replacement anyway.
