Can air duster fix a "stuck down" home button?

Thanks, but that only works if the home button is unresponsive but not when the home button is actually stuck down. You have to get out all the dust and dirt on the inside. Air duster does this, it is normally used for computers and keyboards and stuff like that. It is compressed air in a can. But some people are scared to use it on iPods since sometimes it sprays out liquid. But I haven't seen anyone say that it has screwed up their iPod. I just want to know if anyone has tried this and if it has worked for anyone. I know some people say electrical contact cleaner does the trick but I don't know if it's the same thing or works the same way.
