How to Choose the Right Garage Floor Pressure Washer

  It is very important to choose the right pressure washer before pressure washing garage floors. You will need a powerful machine to handle the job if your garage is too large. For smaller garages, a less powerful pressure washer will suffice to clean the garage floor. Choosing the right nozzle and pressure washer wand is also important. Narrow-angle nozzles are better for getting into tight spaces, while wide-angle nozzles are excellent for covering large areas quickly.

Electric vs. Gas-Powered Pressure Washers

There are electric and gas-powered pressure washers, but gas models are typically stronger. This is why it is often best to pressure wash your garage floor with a gas-powered pressure washer. If you are cleaning your garage, you should use gas-powered washers with at least 3,000 PSI and 3 GM.

In an enclosed garage, however, you should never use a gas-powered machine, which can be deadly. The garage door must always be left open.

When a power outlet is available and the garage floor isn’t particularly dirty, use an electric pressure washer to clean. Prior to pressure washing, read all safety instructions and follow them.

Choosing Between Pressure and Power Washers When Pressure Washing Garage Floors

Power washers should not be confused with pressure washers. Surfaces are cleaned with both high-pressure and hot water, but the latter mainly uses hot water. If you plan to use hot water around cars or other delicate items, use caution when power-washing to get rid of tougher stains. If you’re cleaning the garage floor, you may not need a power washer.

Sweep Up All Debris on the Garage Floor

The next step is to sweep up debris such as leaves, sticks, and other objects that may be blocking your path. Make sure to sweep thoroughly and maybe even use a vacuum cleaner. Additionally, this is a great time to work on any oil or grease stains that you think may be particularly tricky. Then, use a garden hose to rinse the garage floor before pressure washing.

Preparation of the Degreaser

Your garage floor accumulates a lot of grime from time to time. Oil stains and grease will require a degreaser before you can wash your garage floor.

It is possible to mix dish soap and water to make your own degreaser, but many commercial ones are available. Follow all precautions and instructions carefully. It is possible to place a degreaser directly in the soap tank of your pressure washer. Degreaser can be applied directly to the garage floor if your pressure washer does not have a soap tank. Degreaser should be allowed to sit for approximately 10 minutes before pressure washing.  

Protect Furniture and Other Items in the Garage

Make sure you cover up any items in your garage that you don’t want to get wet (such as cars, bikes, and other equipment). Imagine spending a lot of time in your garage, on the couch, or watching television. Obviously, you will want to cover or remove these items before washing your garage floor.

It’s important to take precautions when pressure washing, as it can be a messy process. Protecting any outlets is also vital.

Start Pressure Washing the Garage Floor

The garage floor needs to be pressure washed now. We must move from the indoors to the outdoors in the correct direction. The water will make its way outside if you spray outwards toward the door, and it won’t be forced towards the direction of your home.

Pressure wash the garage with a low water pressure before increasing it as necessary. Make sure the cleaning wand is about two feet from the floor and use a wide angle when spraying. Scatter the solution across the garage floor in a circular motion. Don’t stay in one spot too long, as this can damage the concrete.

What Nozzle to Use With a Pressure Washer

There are several types of pressure washer nozzles. When cleaning a garage floor, you should use a wide-angle nozzle with low pressure so that you don’t damage the surface. For particularly tough spots, you can use a narrower-angle nozzle, but you should avoid damaging the garage floor. To find out which nozzle to use, read the instructions that came with your pressure washer.

How to Safely Pressure Wash Garage Floors

It can be messy and challenging to pressure wash garage floors, but it’s important to take safety precautions. Keep children and pets away from the area when using pressure washers. Remember to use proper ventilation when using a gas-powered pressure washer.

Complete the Pressure Washing of the Garage Floor

Remove any remaining dirty water or degreaser. The soap and debris may need to be removed several times to be completely removed. When you’re done, shut off the pressure washer and disconnect any hoses or power cords. It is advisable to wait for the garage to completely dry before walking on the floor or parking a vehicle there. Temperatures and humidity can affect how quickly the garage dries. The drying process can be sped up by using a fan or opening up the garage door.

Final Thoughts

Sweeping loose debris should be your first step. As you move forward toward the door, start using the power washer at the back of your garage (closest to your house). Allow water and debris to wash outward and away from your home by spraying directly onto the garage floor and out toward the door.

Frequently Asked Questions (FAQs)

What is the time required to pressure wash a garage?

It takes some time to pressure wash a garage. Still, it’s not a difficult task. You can expect to spend between one and three hours pressure washing your garage floor, depending on the size of your job. The time needed for this process depends on how dirty your garage floor is at that moment, how big your garage is, and how much pressure you are using.

Should I hose down my garage?

Using a hose with a high-pressure nozzle, a concrete floor cleaner, a deck brush, and a little elbow grease is the best low-budget way to clean a garage floor.

What are some of the best ways to clean concrete garage floors?

You can use half a cup of baking soda in a gallon of warm water as an all-purpose cleaner. Baking soda can also be mixed with a few drops of liquid soap to create a paste that can be used to scrub light stains. To keep your floors clean and remove minor stains, use warm, soapy water which will also be helpful.
