This is by far the best de-greaser I have ever used. Considering that I have been an auto mechanic for several years as well as worked on industrial equipment that is really saying something about this product. Yes I have had some (only available to commercial/industrial business) that clean a little better, but they were quite harsh and required you to wear gloves. This stuff is Eco-friendly, EPA approved, hard enough to clean transmission pans and oil pans back to near new cleanliness, but also gentle enough to get grease and oil stains out of your laundry. That's part of what makes this stuff so great, it's incredibly versatile. In this instance I bought 10 gallons of it to use in my parts washer. My only word of caution is for people not to use it to remove oil stains from asphalt. I have read several comments from others who have said that this stuff will break down asphalt. Which makes sense, asphalt is an oil/petroleum based type of pavement.

This product did not remove the oil left by a repair man, in my driveway. Two applications, both brushed in and hosed off, oil is still there.
