We had them out to our Oakland location for the hotel entrance and the loading area. Our customers noticed the difference the same day.

The parking garage was slick with grease and now it is safe to walk on. They used the right pressure so nothing was damaged.

Our retail center in Oakland is now part of our monthly maintenance. They used hot water and a degreaser that actually worked.

The restaurant patio at our facility was embarrassing before they came out. The concrete looks much better. A few stubborn stains remain.

They removed oil stains from our apartment breezeway that I thought were permanent. Great outcome. I would have liked more notice before they arrived.
