Alright then.

Vinegar and baking soda to deep-clean the cement and neutralize the odor.

Cover the concrete with baking soda and let it sit for a few days (make sure it's not going to rain!), then use a wire brush and white vinegar (cheap by the gallon) to scrub it clean. Finally, wash the mess away with plain water.
