I actually think two of the caps's stems were just the smallest bit wet, and when i pressed down on them, the water went down into the switch. After letting the keyboard dry for three hours (with the PC off, and occasionally shining a high-powered laser into the switch, then waiting a few minutes for the water to evaporating, pushing down the switch and blowing into it to evacuate air), the two switches dried out and are back to normal. I was worried that there would be permanent damage, but there is none that I can see. All switches are accurate and actuate perfectly, so I just had to let it dry out for a few hours. Thanks for the response, though!
