Can You Power Wash Garage Floor? Safety Rules in Detail!

Garage floors get full of dirt and oil stains much faster than home floors. If you let the dirt set into the concrete, you will find it hard to remove it with traditional methods. You may have to resort to exceptional methods like power washing which is designed to deal with extremely tough dirt and grease spots with little to no effort. This article talks you thorugh the right way of power washing garage floor for maximum efficiency and some safety tips to consider.

Can you power wash garage floor?

Power washing garage floor is recommended when the concrete gets encrusted with dirt and automobile oil. Trying to remove set-in grime with scrubbing brushes will lead to no results. You will have no choice but using something extremely powerful such as pressure washing. Given that concrete is hard, pressure washing deals no damage to it.

However, before starting power washing, you have to cover up furniture, electrical outlets and other stuff that can be damaged by water and concentrated detergent. Also, there are other steps to take to make sure that the power washing session brings the desired results.

How to power wash garage floor?

Step 1. Sweep the floor

Before you proceed with the pressure wash, take a brush and sweep off all loose debris. Remember that the pressurized jet cleaning focuses on lifting ingrained dirt and stains. The pieces of debris laying on the floor will be just moved from one place to another by the water jet. That’s why, make an effort to sweep them in the dustpan before you take the pressure washer in your hands.

Step 2. Pre-treat the stains

The next step is pre-treating the oil stains with a degreasing solution. Take a deck brush and work the degreaser into the grease spots. Those at Uooz.com suggest to let the stains soak for 15-20 minutes. If you want to rid the rest of the floor of tiny oil marks, add degreaser into the pressure washer’s reservoir and spread it.

Step 3. Cover up furniture and electrical outlets

Even if you target the floor when pressure washing, the water may deflect and splash the walls, furniture, tools and outlets. You don’t want all these items to come into contact with water. That’s why, you are good to cover them up with waterproof materials. Also, make sure you close the door connecting your home and garage.

Step 4. Choose the right pressure setting

Once you have prepared the floor, it’s time adjust the water pressure of the power washer. You have to choose a PSI (pressure per square inch) as high as to deal with the hard-to-remove stains effectively. At the same time, the PSI shouldn’t damage the concrete which can withstand to extreme tension but like any other material has a limit. That being said, your best bet is going with a PSI of 3,000. If the power washer doesn’t show the PSI in numbers, always choose the low setting and check the pressure in a far corner of the garage.

Step 5. Add the cleaning agent

Even if the pressurized water jet can remove the stubborn dirt itself, adding a cleaning solution can help do it faster, saving electricity on power washer operation. Pour the detergent into a bucket and add the amount of water as required by the manufacturer. Mix well and pour the solution into the power washer tank. If your washer doesn’t have a reservoir, AllGarageFloors recommends to spread the detergent directly on the floor. Let it soak for 20 minutes without allowing it to dry out. If it starts getting dry, add some more solution to keep it wet.

Step 6. Start power washing

The final step is taking the power washer and getting down the pressure cleaning the floor. If you wonder how can you power wash garage floor more efficiently, hold the device at least one foot above the floor and start from the fartherst point from the garage door, moving backwards. This will make sure not an inch of dirty concrete is left behind.

Aim the power washer toward the garage door to make the water drain in the driveway’s direction rather than damaging your home foundation. If you notice the concrete etching, lower the pressure setting. If it’s the lowest setting, lift the power washer a bit higher above the floor to reduce the impact.

Tips to pressure washing safely

Power washing is quiet a risky thing to do if you don’t follow the safety guidelines. First of all, you should be aware of the crushing force of the water jet the power washer releases. If you power wash barefooted or in flip flops, the high-pressure jet can rip your skin off your foot. You are best off wearing a pair of old rubber boots or other shoes that cover the feet entirely to make sure your skin is protected. Don’t use new shoes as they can get easily damaged by the powerful spray.

Another safety tip provided by OverHeadDoors is not to place your hand under the power washer spray to check the pressure. It can rip your skin and cause fractures. Moreover, you can wear protective glasses to prevent droplets of water hitting your eyes at high speed. It can be fairly painful, in spite of the tiny size of the drops.

Power washer or pressure washer

Both terms are used to refer to a machine that removes tough stains by means of high-pressure water. However, there is still a difference between the two. Power washer uses hot water, while pressure water cold water. This makes power washer more efficient when it comes to tackling extremely stubborn dirt, as well as more expensive to rent.

Closing line

So, can you power wash garage floor? Yes, you can use this cleaning method to rid your garage floor of set-in dirt, grease spots and soils. Make sure, though, you follow the safety rules in detail to keep bodily harm and garage equipment damage at bay. Use a concentrated detergent to loosen dirt and oil faster.
