Questions & Answers

Ask a Question
  • How does it work on concrete driveways? how do you apply on driveways if it is good for that?

    D/2 works very well on concrete. Driveways are tricky because they are constantly being used. You can spray it on and leave it at that, or spray and brush with a soft bristle brush. The D/2 will penetrate the stone and continue to work overtime to clean from the inside-out.

Best stone cleaner out there

I am the biggest fan of D/2. I started cleaning veteran grave markers in the back hollows of SW Virginia because I felt like I needed to. Since I’ve started, I’ve cleaned over 150 markers and monuments, including a 15’ tall granite in a town center. Everyone asks what I use to clean. I always say “D/2, water and a good brush.”

Always prompt on shipping

Atlas was prompt on shipping out my order. And the 4 gallons of D2 was packed nicely.
