Brush them out with a wire brush, particularly a power one. Then treat them with naval jelly to chemically clean them. After that, you will need to wash them with warm water and dry them with a hair dryer. Paint as quickly as possible with a good primer.

OxySolv works well - it is a phosphate cleaner/treater that is very effective. It depends on how much rust you have - you will have to clean out the flaky stuff with a bruch first regardless. I don't recommend POR-15.

I would suggest cotton gloves, not latex ones. I wear my welding gloves (medium weight cowhide) when doing this work, they protect me from the sparks from the grinding wheel/wire brush.
