Glad you're sorted now, just though I'd share what I do... I use a handheld steam cleaner (little attachment on one you'd have to clean the kitchen floor). As well as thoroughly cleaning, it seems to get rid of any smells too.
I remove any dirt with the smooth side of a sponge with a little hot water and washing up liquid, then steam clean, dry with a clean cloth and put a little tin foil over the grommit. Then on brew day, I sanitise with Star San as normal. In total I probably spend 10 mins on it all... worth the peace of mind when the airlocks bubbling away.
