Yes they can. You can remove the seal, clean and re-grease it and put the seal back on. I've done this who knows how many times. It's not as easy/effective as with cup and cone bearings but it can definitely be done.
However, it's still recommended to remove it for easier cleaning so might as well replace while at it.
Yep. I'm using dentist's pick for removing the dust covers, it's a nice stiff and thin tool for this job
