    Power jet wash and any decent detergent.

    Muratic acid…I use it all the time to clean concrete. However, be extremely careful wearing protective equipment when using it. It is basically hydrocloric acid, the same acid in your stomach, only stronger. You can buy it at most hardware stores, and dispose of any leftover acid so that you dont have it sitting around. It rinses clean with water as most acids do.

    I dont think a power wash or even muriatic even came close to cleaning a concrete sidewalks after my house had a fire that burned down a porch with a concrete floor.

    What the contractor used was a sand blaster company.

    The sand blaster came and cleaned it to near new or better. Those are same people who do old building sand blasting so a look in Yellow Pages for your area will show who is doing that .
