Before you start, you should be familiar with how a pressure washer works. It sends out a very powerful stream of water, which can slice through your toes if you aren’t careful. If you plan to use a gas-powered pressure washer, it does emit fumes, including carbon monoxide gas. You should be sure that this type of pressure washer is placed outside of the garage when you do this job.
If you have tough stains or oil spills on the garage floor, you should spray it with a degreaser or concrete cleaner before you begin. You will use lower pressure to do this, and most pressure washers come with a soap nozzle that is set up for it. You can also get a pressure washer brush to scrub the solution. This will help work the deeper stains out of the concrete.
Once you are finished with the cleaning products, you can spray it clean. Move from the back of the garage to the front and push all of the dirt, debris, and dirty water to the outside. Once you finish, your garage floor should look as good as new. Understanding this process before you begin is a great way to make sure that you end up with a clean garage floor.
