Allow the bleach solution or detergent to soak in for a moment to make sure that all the black mold is eliminated. When you are done scrubbing and letting it soak for some time, you can go ahead and rinse with a power washer to eliminate the entire solid biological substance out of the concrete. 

Also, there are questions on whether vinegar is an excellent substance to use to get rid of the black mold.
