MikeB Posted May 5, 2012 Share Posted May 5, 2012 Strong detergent and a pressure washer, or just let the weather and time take care of it. Besides it is driveway art and why would you want to remove it?Do not use muriatic acid in any concentration. It will etch the concrete and then you will really have a permanent eyesore.

Muriatic acid is the norm for concrete cleaning, there are a million concrete pools that are cleaned with a strong solution every year. It also preps the floor for overcoatings like epoxy as well. Pressure washers pop rocks and leave etchings as well. -dag Link to comment Share on other sites More sharing options...
MikeB Posted May 5, 2012 Share Posted May 5, 2012 In the hands of the inexperienced a pressure washer can permanently damage masonry, whether it is a driveway or brickwork. With the correct pressure and nozzle it is the recommended method. I have been personally involved in the concrete business for over thirty years and I can assure you that muriatic acid is not the "go to" product for cleaning concrete. The reason it is used to prep floors for epoxy coatings is because it reacts with the cement and essentially dissolves the surface layer. The vast majority of masonry cleaning products no longer contain hydrochloric acid. Do a little research and be enlightened. Link to comment Share on other sites More sharing options...
nater Posted May 5, 2012 Share Posted May 5, 2012 When I had to prep concrete swimming pools in the Spring, we used pressure washers and sulfuric acid. Most of the stains we had to clean were caused by hard water and rotting leaves during the winter. I couldn't say if it was the "right" way, but it was what we were told to do to earn our paychecks before the season opened. Link to comment Share on other sites More sharing options...
mikeee Posted May 5, 2012 Share Posted May 5, 2012 Why not stain the concrete with a color/finish that will hide any stains from your pyro chemicals.Concrete can be stained to look like marble if you want it to. It has turned into quite an art form.Does anyone know how to remove pyro stains from your shorts after a shell cato's in the tube?:-) Link to comment Share on other sites More sharing options...
