Gather Your Supplies

When it comes to removing decking oil from concrete, the first step is to gather your supplies. You will need a pressure washer, detergent, and scrub brush. A pressure washer can be rented or purchased at most hardware stores and home improvement centres. Detergents specifically designed for cleaning decks are also available at these locations as well. The scrub brush should have stiff bristles that won’t damage the surface of the concrete when you use it.

You may also want to wear protective clothing such as gloves and goggles while working with chemicals or power tools like a pressure washer. If you plan on using any type of chemical cleaner, make sure you read all safety instructions before beginning work on your project. It’s important to protect yourself from potential hazards associated with these products.

In addition to gathering supplies for cleaning up decking oil from concrete, you’ll need some basic tools like a broom and dustpan or vacuum cleaner if needed; buckets; rags; sponges; paper towels; ladders (if necessary); drop cloths (to cover plants); plastic sheeting (for protecting furniture); tarps (for covering large areas). All of these items can easily be found in local stores or online retailers, depending on what works best for your needs and budget.

Gathering the right supplies for your project is essential to ensure you have everything you need to successfully remove decking oil from concrete. Now it’s time to prepare the area before starting the process.

Key Takeaway: Gather a pressure washer, detergent, and scrub brush to remove decking oil from concrete. Wear protective clothing such as gloves and goggles while working with chemicals or power tools. Also, have basic tools like buckets, rags, sponges, and paper towels ready for the job.

Prepare the Area

Before you start pressure washing, it’s important to prepare the area. This means covering nearby plants and furniture with plastic sheeting or a tarp. If you don’t have any of these materials on hand, an old blanket or drop cloth can also work. Make sure that whatever material you use is thick enough to protect your belongings from water damage.

It’s also a good idea to move anything that could be damaged by the pressure washer away from the area before you begin cleaning. This includes items like potted plants, outdoor furniture, garden decorations and other fragile objects in close proximity to where you’ll be working.

You should also check for any electrical outlets near the area and make sure they are covered up so they won’t get wet during the process of pressure washing. It’s best practice to unplug all cords connected to appliances in case there is any accidental splashing while using your power washer as well.

Finally, make sure there are no pets or children around when operating your pressure washer, as this can be dangerous if not handled properly.

Before pressure washing, it is important to prepare the area by removing any loose dirt or debris. This will ensure that the pressure washer can effectively clean away the decking oil from your concrete surface.

Pressure Wash

Pressure washing is a great way to remove decking oil from concrete surfaces. It’s fast, efficient and can be done with minimal effort. Before you begin, make sure you have the right safety gear – protective eyewear, gloves and long sleeves are all recommended.

Once you’re ready to start pressure washing, it’s important to adjust the nozzle settings correctly for maximum efficiency. Start by setting your pressure washer on low power and gradually increase it until you reach the desired level of cleaning power. This will help prevent damage to any underlying materials or surfaces that may be exposed during the process.

Next, hold the wand at an angle so that it is pointing away from any nearby objects or people as well as yourself. Begin spraying in a back-and-forth motion over the area where you want to clean off decking oil residue from concrete surfaces. Make sure not to stay in one spot too long, or else this could cause damage due to the excessive water pressure being applied in one area only.

When finished with each section of surface area, move on to another section until all areas have been covered thoroughly with pressure washing techniques using your preferred nozzle settings and angles of approach while keeping safety precautions top of mind throughout this entire process.

Pressure washing is an effective way to remove decking oil from concrete, but it’s important to make sure you clean up any remaining residue before moving on.

FAQs in Relation to How to Remove Decking Oil From Concrete

How do you remove dried oil from concrete?

Removing dried oil from concrete can be a tricky task. To start, it’s important to scrape away as much of the oil as possible using a putty knife or other flat tool. Next, you’ll need to use an absorbent material such as kitty litter or sawdust to draw out any remaining oil. Once this is done, mix together equal parts baking soda and dish soap with warm water and apply the mixture directly onto the stain. Let it sit for 10-15 minutes before scrubbing with a stiff brush and rinsing off with cold water. Repeat if necessary until all traces of the oil are gone.

Does WD 40 remove oil stains from concrete?

Yes, WD-40 can be used to remove oil stains from concrete. It is important to note that the product should not be applied directly onto the stain but rather sprayed onto a cloth and then wiped over the affected area. This will help prevent any damage or discolouration of the concrete surface. Additionally, it may take several applications before all traces of the stain are removed. For best results, use a stiff brush after applying WD-40 to scrub away stubborn stains.

What removes oil from concrete?

The best way to remove oil from concrete is by using a degreaser or detergent. Start by wetting the area with water and then apply the degreaser or detergent directly onto the affected area. Allow it to sit for 10-15 minutes before scrubbing it with a stiff brush. Rinse off any remaining residue and repeat if necessary until all of the oil has been removed. For stubborn stains, you may need to use an industrial-strength cleaner such as trisodium phosphate (TSP). Be sure to wear protective gear and follow the manufacturer’s instructions when using these products.

What is the best product to remove oil from concrete?

Degreasers are specifically designed to break down and dissolve oil, grease, and other petroleum-based substances. They can be used on various surfaces, including concrete, asphalt, metal, wood, stone, and more. When using a degreaser on concrete, it’s important to use the right concentration for the job – too much could damage the surface or leave behind residue. Additionally, always wear protective gloves when handling any chemical products, as they can cause skin irritation or burns if not handled properly.


Removing decking oil from concrete can be a daunting task, but with the right supplies and preparation, it doesn’t have to be. Pressure washing is an effective way to remove decking oil from concrete, but you should always make sure that your pressure washer is set on the lowest setting so as not to damage the surface of your concrete. Once you’ve finished pressure washing, clean up any remaining debris and residue before allowing the area to dry completely. With these steps in mind, removing decking oil from concrete should be a breeze!
