The info I have given will remove the sealer, as far as the efflorescence goes, I'd be inclined to remove the sealer, then let the paving breath and properly dry out of the next few summer months, and see if it stops coming through, Also with the steam cleaner, what the guy needs is high heat but low pressure, if he knows how to use it, he'll be fine.
