All-Purpose Masonry & Concrete Cleaner - Concentrated, Non-Toxic Powder - 2 lb Pail

This product is great! I spilt an entire bucket of cooking oil all over my back porch and tried tons of products to remove the stain. I used this and it’s almost completely gone. One more treatment and should look good as new. Wish i had taken a before and after pict. After second clean, it look brand new. This product is a miracle worker.

Used cleaner and followed the instructions. Didn't remove any stains.

This masonry cleaner was used to clean my concrete driveway. It mixed up easily with no odor and I applied it with a pump sprayer. I didn't realize how dirty my driveway was until after letting it soak in. I used a pressure washer to complete the cleaning and found that the rinse water was brown with dirt from the driveway. After drying, my driveway is as bright as the day it was new. I highly recommend this product for cleaning concrete and was completely satisfied.

After reading the negative reviews of this product, I took great care to mix and apply as directed hoping this was the reason for reported poor results. I waited 30 minutes then used my power washer to clean the seasonal moss and algae build up on my patio pavers, granite steps, slate walkway and brick walls. The product had virtually no effect on the time and effort normally used to clean these surfaces. A totally frustrating and time wasting endeavor. There is no justification for the high cost of this powder. A box of Oxi-Clean powder does the same thing for a fraction of the cost.

plugged up my pressure sprayer because of the particles NOT dissolving even though we used hot water for mixing. Green type cleaner for driveways cheaper and does better job.

Cleaned driveway. Looks like new concrete! Husband didn’t use power washer as recommended just strong stream from hose but still looks great.

This stuff is amazing. Sure beats paying someone every spring to come clean the driveway. Now I’m waiting for the sealer to come in today.

Didn't work very well on brick to remove dirt. Bought another product that was much better.
