Sticky Guck On Scissors

I don't know about you but over time my scissors seem to get a build up of sticky stuff on them. But them again I seem to use them for everything in my crafting Does anyone else have this problem? If so, what do you use to clean of your scissors? I use nail polish remover which I am totally sure is not the right product but I am not sure what else to use. Any other suggestions?

Undo works perfectly everytime too

Goo be Gone works great. I have the same problem of getting my sticky from cutting through adhesive and have found that cleaning them once a month really helps.
