Mold cannot grow without moisture. So you need to think about how you are going to dry them after cleaning. If the humidity in your home is too high the mold will just come back.
To clean them, wash them with an unscented detergent and a little bleach. Make sure the detergent does not contain ammonia (the ammonia will react to the bleach). Rinse. Repeat if necessary.
You want to use unscented detergent. Often the visible signs of mold go away but you can still smell the stale oder. If you use unscented detergent it will make it easier to detect the oder of mold after each cleaning.
Check with local dive shops to see if they have a detergent for cleaning the inside of BCDs. McNett Corporation (
McNett ) has cleaner for BCDs which kills organic residue.

P.S. you have to figure out some way to have the boots rest upside down with the toes pointing slightly higher than the heel. This will let the moisture in the boot drain out. You need to do the same thing for the gloves or you might be able to turn them inside out.
