Liquid dish soap or laundry detergent will remove most oil stains on pavers. Directly apply the soap to the stain and allow to sit for 20-30 minutes. Then scrub with a nylon bristle brush and rinse with hot water. Repeat this step as needed.
USE WHITE VINEGAR
Cleaning pavers with vinegar is one of the simplest ways to eliminate stubborn oil stains, or moss, and algae on pavers, particularly brick ones. Vinegar is 5% acetic acid, making it a fairly powerful cleaning agent for breaking down oil, dirt, bacteria, and other kinds of stains. Get white vinegar.
As soon as you notice a greasy or oily spot on your paver patio, apply a layer of kitty litter onto the stains. Let the kitty litter sit on the spot for at least 48 hours. Gently sweep the kitty litter off with a broom. You may need to repeat this step several times.
There are useful tools for cleaning paving stones, such as joint scrapers, sweepers, and pressure washers. In addition, pavers can be cleaned with a small pickaxe, broom, and garden hose.
Dawn Dish Detergent
All you need to do is pour a generous amount of dawn over the oil and use a large bristle brush to scrub the stain until you can see that it is pulling away from the ground. Rinse and repeat until the oil disappears. This might just be the cheapest solution you'll find!
WD-40 can do more than eliminate unpleasant door squeaks – it may also help remove oil stains in your driveway, according to Reader's Digest. That's because it has ingredients that can penetrate grease. Spray a liberal amount on the area and let it sit for 20 minutes, adds Organic Lesson, then wipe the area clean.
Generally, interior pavers that have been grouted and sealed just need to be swept, mopped, and spot-cleaned as needed with a gentle, non-acidic multipurpose cleaning solution, such as Enviro Klean All Surface Cleaner or Light Duty Concrete Cleaner.
To clean paver slabs, you can use a detergent, such as Dawn, or a vinegar-water solution that is gentle enough to effectively clean without causing damage to your concrete pavers.
Dry brushing with or without application of clean sharp sand. OR High pressure water jetting with or without detergent. OR Apply fungicides. Use ordinary bleach or calcium chloride followed by sodium hypochlorite dissolved in water (1kg in 5 litres) then scrub with stiff brush.
White vinegar is good for cleaning pavers, though it's also acidic enough to erode the stones' surface. Diluted vinegar can be used safely to clean paving stones, though it should be used sparingly and infrequently to protect your paving from damage.
Will Vinegar Damage Pavers? Yes, vinegar is NEVER safe to use on pavers. It can cause a lot of damage, and you may have to replace a lot of the pavers if you try this. I know that vinegar is often used for household cleaning projects, but when it comes to your patio, it's a big no!
Removing oil stains from the surface of outdoor pavers is a fairly simple task with Cleaner/Degreaser, a commercial-strength detergent that is specifically designed to remove not only oil and grease films, but also adhesive tape residues, rubber tire marks and scuffs from concrete floors and other hard surfaces.
The most common oil remover is the degreaser, Simple Green. While Simple Green is most effective at removing fresh oil stains from concrete, it's gentle on outdoor concrete, and you can easily apply it to large areas. Further, it's inexpensive, and you can buy it at any hardware or auto parts store.
Depending on the material of the paver (non-coloured concrete is safe), CLR may be suitable. Always spot test in an inconspicuous area first. Make sure the pavers are not coloured, stamped, sealed or coated.
Use a specialist cleaner
Try a specialist cleaner like Wet & Forget, at Walmart, which you spray onto the surface of the paving and leave. It can also be used on steps, fountains, patio umbrellas and other smaller outdoor areas. It's bleach-free and non-acidic but will remove mold, moss and grime without any scrubbing.
On the other hand, baking soda is useful because it is slightly abrasive, which is excellent for the rough surfaces of paving slabs. When it is mixed with water, it can dissolve dirt and grease, and like vinegar, you'll only need a brush or broom when cleaning.
If you are prepared to use chemicals to remove algae, lichen and moss from your pavers, it is important that you use plastic sheeting to protect other plants in the vicinity. A solution of one cup bleach to four litres of water should do the trick.
WD-40 is a lubricant dissolved in a solvent. While it can break down grease and oil to a certain degree, it also adds back some. This might be desirable if you are cleaning a hinge, conveyor, or corrosive-prone part, but not if you need it truly clean.
You may want to even let it sit overnight. If you do, consider placing a plastic “tent” or covering over the poultice and stain to protect it from rain and traffic while it dries. In most instances, one application of Oil & Grease Stain Remover will remove embedded grease stains from concrete.
