No, they are *not* vacuum sealed, nor are they covered with 'oil'.
Open up a HD, and take a peek inside. They got vent holes (actually, I think most say do not block this vent hole on the HD themselves). They also have little micro filters, in those vent channels.
As for "cleaning" them, that is almost impossible for the consumer to do, we just don't got the needed equipment to keep the crap off the platters, and even if we did, it still is not worth the effort unless your a recovery place.

I disagree. New drives are usually batch tested. Hence the reason some are bad some are not. RMA drives are fully tested to make sure they will not fail again. I have had good luck with stuff that came back after RMA with the exception of 1 intel board.
Xarick, sorry, that isn't the case. I have had plenty of back to back RMAs because the RMAed drive died within a few days-months. Just because you have had 'good luck' on your RMAs, don't mean everyone has the same luck.
Like I said, all they do is take parts from other RMAed drives (when available), put it all back together, and send it to testing. After the format, if everything is 'ok' they ship it out again. If not, they take it apart, and try again. Rinse & repeat.
I know a guy who worked at the plant, and that is what they do.
