Yep, I agree. Water is all you need. It is the pressure of the water coming out that blasts away any dirt. I had a great time doing our driveway. I used the sprayer to write a note on the cement. We had "I love Dave" on the driveway for about a week! Have fun!

Hello! I pressure cleaned my walk last summer with nothing more than water.I'm sure you could use something but not sure what so as not to kill grass and flowers or that would hurt animals.My walk had never been cleaned and the home was built in 1940.The walk looks new.Give it a try.
