Stiff operating turnouts

[foulrift]

I have noticed that a few of my turnouts don't operate as smoothly as I would like.I am assuming that something,perhaps glue from when I was ballasting the track got under the moveable part of the turnout(I use Peco turnouts). Is there a safe way to free up the turnout? I have thought about putting alchol on them but wasn't sure if that was the right thing to do.
Any solutions would be appreciated.
