Having a sticky fire button problem

[samiroza0]

Hey guys, I have a lavabox and I absolutely love it. Recently ive noticed that the fire button is getting slightly stuck and not clicking on the top portion but if i hit the lower portion of the button it works fine. I'm guessing this is because I got a tiny bit of juice in the button. I've tried alcohol pads and they havent worked very well because i cant get anything in the gap around the button. I was wondering if you guys recommend some other solution or maybe even an alcohol solution instead of pads in order to clean it. I just dont want to damage the board or anything. Thanks a bunch!
