Cleaning Concrete

• 1). Rent a portable power washer from your local tool rental center or home improvement center. These come in either electric- or gasoline-powered models that use a home garden hose as a water source and use a spray wand like a car wash to deliver a stream of pressurized water.
  
  
• 2). Wet the concrete to be cleaned, and then apply the cleaning product of your choice according to the directions. These chemical products help to strip off grease, oil and dirt, and some actually help to bleach and brighten the appearance of the concrete. A solution of 50% bleach and 50% water makes a pretty good, inexpensive cleaner.
  
  
• 3). Use a long-handled scrub brush to maximize cleaning potential as the cleaner is applied.
  
  
• 4). Rinse the concrete thoroughly with the power washer. Make sure to remove all the solution and any loose debris from the concrete.
  
  
• 5). Allow the slab to dry completely.
