It is basically electrical contact cleaner. I saw some in a repco (i think) catalogue the other day for like $10. Don't know if its still current. Or even better find a forum member with a can. You will only need a few squirts.
May make a difference, may not. Couldn't hurt to do it for the peace of mind though. In fact I just did mine today (borrowed someone else's can!)
