Garage floors are messy, oily, greasy and blah blah blah. But this condition can come to an end if you have a good pressure washer for garage floors

Pressure washing the concrete garage floor is much more convenient than washing it with a bucket and a brush. There is no doubt a pressure washer can remove oil stains, grease, sticky mess, and tough dirt from the surface of the garage floor within no time. All you need is a good pressure washer and a concrete cleaner. And sometimes an attachment to give it an even more refreshing look by scrubbing.

Coldwater Pressure Washer or Hot Water Pressure Washer:

Coldwater pressure washers are the traditional machines that are being used for residential and light commercial cleaning purposes. Whereas hot water pressure washers are expensive, heavy machines that work with hot water.

Hot water washers have a specialized system to raise the temperature of water to make it hot before pressure washing. The heating system makes them expensive but powerful enough to blast away any type of tough stains of oil and grease from the surfaces. These hot water pressure washers are called power washers. The main difference between a pressure washer and a power washer is the hot water mechanics within the machine. 

However, a good cold water pressure washer with optimum PSI and GPM can wash the dirty and messy garage floor easily. The techniques and procedures of cleaning this mess also play an important role which we have discussed at the end of the article.

Safety Measures To Take Before Pressure Washing Garage Floor

best pressure washer for garage floor

You may think that it is easy to clean a garage floor with a pressure washer but it is not that simple and easy for many. First of all, knowing how to use a pressure washer safely is important for you if you are new at pressure washing. Then it is also important to take certain precautions and safety measures before washing your concrete garage floor. Here is a shortlist of some precautionary measures:

  • Always remove the objects from your garage that are prone to high-pressure water
  • If there are any large pieces of debris on the floor, such as leaves or branches, get rid of them before starting to pressure wash. This will help to avoid spreading the debris around and make your job a little easier and risk-free.
  • Clean or sweep your garage floor while it is dry so that small objects cant damage you or your property while pressure washing. (Pressure washers have huge water pressure. When small objects come in contact with the pressurized water, they can fly away extremely fast in opposite directions thus creating a chance to damage you or your property.
  • Make sure to use protective gear like gloves and steel-toed shoes
  • If you are using a gas-powered pressure washer to clean your enclosed garage, always make sure there is an open space for carbon monoxide to move out. If there is no space inside, it is best to place it just outside the garage so that harmful fumes cant reach you. (Do you know why is it extremely dangerous to run a gasoline engine in an enclosed area? Or How dangerous is it to run a gas-powered pressure washer in an enclosed building? This is because gas engines emit high concentrations of carbon monoxide. If the building is enclosed, the concentration of CO reaches the levels that can kill a man. And this happens so suddenly that you don’t even have time to think that what it is.)
  • Do not use wet hands while starting and using an electric pressure washer.
  • Always point the nozzle downwards. Do not point it directly at someone or your own feet. It can rip your skin apart.
  • Do not replace the nozzles without shutting down the water completely.
  • Never run a gasoline engine with low oil unless you want to buy a new one.

Tips To Clean Your Concrete Garage Floor With A Pressure Washer

Concrete garages can be difficult to clean. Not only is the concrete itself difficult to clean, but the oil and grease that often accumulates on garage floors can be tough to remove as well. In order to clean your cemented garage floor with a pressure washer, follow these tips:

Tip # 1

Always use a good pressure washer for your garage floor. The PSI and GPM is an important things that can make a difference in cleaning results. Therefore, choose wisely for pressure washing cement floors so that they can shine like before.

Tip # 2

Do not use a pressure washer on the painted or sealed garage floor because high water pressure can rip off the paint. However, you can wash epoxy coated floors without any fear of damage.

Tip # 3

Declutter your garage. Before starting pressure washing remove everything from the ground. Things that are prone to water or high pressured water must not be there on the ground.

Tip # 4

Always choose and use nozzle tips wisely when washing concrete garage. The green one is for light cleaning, while the red and yellow tips put more pressure on a small area and can blast the top layer of concrete off. Therefore, use them with extreme care to save the floor.

Tip # 5

Always aim the pressure washer at a 45-degree angle when starting. You can adjust the angle according to the required floor conditions.

Tip # 6

Pressure washing can leave behind visible lines and streaks, often near the end of the garage. This is often due to human error, as you may get tired and don’t focus as much as you started. A turbo nozzle is a be the best solution for cleaning larger areas. It rotates the water and cleans better than a regular nozzle, without leaving lines.

Tip # 7

If your garage is heavily stained with dirt, mould or mildew, oil and grease or any other substance, use a concrete cleaner to take care of the problem. Cleaners work by pulling the dirt out of the pores of the surface and leaving it open so that you can get a good epoxy coating or seal if you decide to use an epoxy coating or concrete sealer later on.

Tip # 8

Pressure washing is not an effective way to remove sealers or coatings from concrete. When the water is concentrated in one area, it can blast the top layer of concrete off and leave various etch marks. As the strength of the concrete is mostly in the top layer, so once that’s gone, your concrete is more likely to deteriorate and prone to damage.

Tip # 9

Seal the concrete if possible. Concrete sealing is a process that can help keep dirt particles, oil and grease stains from entering your concrete’s pores. This will help in keeping your concrete garage cleaner for a longer time, and it will be easier to clean and pressure wash it.
