How To Clean Diesel Off Of Concrete?

Over the diesel fuel on the concrete, sprinkle cat litter. Distribute it evenly across the entire area. Allow for a 10-minute soak time for the kitty litter to absorb the gasoline.

How do you get diesel stains out of concrete?

  • Although I am unfamiliar with #2 heating oil/diesel, I feel that removing this product/odor from a basement will be a long-term process.
  • Cleaning gasoline from concrete is difficult, but it can typically be done with cat litter (as indicated) and then laundry soap powder combined with a little water and allowed overnight to “pull” out the gasoline. Even so, it’s possible that it’ll take more than one attempt.
  • I’m not sure if this would be safe in a basement, but here’s a link to something similar that would work for diesel:
  • “In a clean empty gallon milk jug, combine hot water, ammonia, washing soda, and vinegar. After shaking the jug, clean the area where the fuel was spilled with it. This will disinfect the area and remove any odors.”

How do I clean diesel off my driveway?

A scrub brush or long-handled push broom, a hose, and liquid dish soap are required to remove oil stains from a driveway. Using a squirt bottle, squirt the dish soap straight over the diesel stain, then add a few drops of water to help the soap spread. Scrub the oil stain with soap and water. This forms an emulsion, which lifts the oil from the asphalt. Using water from a hose, rinse the soap away. Repeat the cleaning process if grease streaks appear in the water. Warm water will aid in the removal of stubborn stains.

Does diesel weaken concrete?

Q: Will concrete floors degrade if they are exposed to petroleum-based lubricating lubricants and transmission fluids?

A.: It’s been stated that pure mineral oils like gasoline, fuel oils, lubricating oils, and petroleum distillates don’t harm mature concrete (Refs. 1 and 2). However, according to a 1950 book (Ref. 3), adding fatty oils to lubricating oils improves their performance (animal and vegetable oils). These oils have the ability to breakdown into fatty acids, which dissolve concrete. We don’t know if modern lubricating oils contain fatty oils, but they certainly have additives that help refined-petroleum base stocks work better. We don’t have any data on the concrete impacts of such compounds.

Because of oxidation, it’s also known that used lubricating oils have increased levels of acidity. The references listed, however, do not discuss the consequences of used vs. virgin oils. It’s probable that used oils will destroy mature concrete due to their increased acidity. However, if that’s the case, expect to see a lot of deteriorated, oil-stained garage floors. Have any of our readers seen concrete deterioration in industrial floors that have been subjected to oil spills on a regular basis?

Readers Respond

A reader wrote in to ask if exposure to petroleum products causes concrete floors to decay in the March 1997 Problem Clinic (pp. 314-315). I have some experience that might be able to help with a partial solution. I was hired as a concrete construction engineer to look into serious concrete deterioration of reinforced-concrete foundations, piers, and beams beneath a paper machine at a factory in British Columbia. The concrete was poured in the late 1920s and may have contained saltwater aggregates. Lubricating lubricants from machinery flowed over particular portions of the concrete over the years, causing deterioration that had advanced several inches into the concrete. The concrete was of good quality and exhibited no symptoms of deterioration away from the oil exposure, with core strengths of around 3000 psi.

As a result, we know that lubricating oils were the primary cause of concrete damage in this situation. It is hypothesized that lubricating lubricants from the past (and possibly the present) had sufficient sulfur, which changed to acid in the alkaline concrete over time. The concrete floor had significantly degraded in sections where diesel oil had been pouring continually for almost 20 years at another business I inspected, where diesel injectors were being remanufactured. The oil’s chemical onslaught caused the degeneration.

Does diesel evaporate from concrete?

In our section of the Southwest, concrete contractors utilize diesel fuel to cure the concrete. Is this a viable method of concrete curing in the desert? In the summer, it appears to evaporate in a matter of hours, yet it appears to be effective throughout the Cooper months, or is this just an illusion? Other than water or a cover, what would you recommend as the best cure in this area?

A: It seems unlikely that diesel fuel, which evaporates in a few hours, would be adequate in the heat. When tested in accordance with ASTM C 156, “Water Retention by Concrete Curing Materials,” the concrete must lose no more than 0.055 grams of water per square centimeter of surface in a period of 72 hours, according to ASTM Standard Specification C 309, “Liquid Membrane Forming Compounds for Curing Concrete.” This test is carried out on a specimen covered with a standard amount of liquid membrane curing agent in a curing chamber at 100°F.

If diesel fuel evaporates in a matter of hours, it can’t possibly hold moisture for the time period specified by ASTM C 309. Although diesel fuel appears to function better at low temperatures than at high temperatures, there does not appear to be a clear technique to assess its performance in these conditions.

Concrete cures more slowly at low temperatures and hence requires more time to benefit from the curing medium, canceling out at least some of the benefit of slower diesel fuel evaporation at low temperatures.

If diesel fuel were a good and acceptable curing agent, it’s conceivable that someone would market it under a brand name.

If water or a cover, such as polyethylene or waterproof curing paper, are not available, the optimum curing option is usually a curing compound that meets ASTM C 309. If there is any doubt about its efficiency at extreme temperatures such as those seen in the desert during the summer, the curing component could be applied thicker.

How do you get rid of diesel smell?

  • Vinegar with Baking Soda Baking soda and vinegar are both natural deodorizers and stain removers that can help you rid the smell of diesel out of your clothes for a low cost.

How do you remove diesel from block paving?

Diesel is an oily fuel. I’d try throwing some cheap clay kitty litter on the problem area. Perhaps you could tread on it and “grind” it into the stain. Place a heavy layer of litter on the floor and leave it for a day or two. Some of the oil should be absorbed by it. Sweep it up and replace the litter. It should be able to absorb more oil in the future. Oil absorbent named “Zip Zorb” is sold in auto parts stores, and it appears to be a fancy, specialized name for cat litter!

The location would then be scrubbed with a hard scrub brush and a strong solution of TSP (trisodium phosphate) and boiling hot water, followed by a rinse with more boiling hot water. TSP is available at hardware stores. It’s either powdered or granular. I’ve even used a layer of plain old cornstarch to absorb oil stains, but I think cat litter would be more cost-effective and practical for this use. Best of luck!

How do you remove diesel from gravel?

Combine a package of baking soda and a cup of fine grain kitty litter in a mixing bowl. Blend it thoroughly, then pour it over the spill carefully. To avoid forcing the oil further into the driveway material, avoid blotting the area before applying the mix.

Allow at least two hours for the mixture to soak into the oil. After the majority of the oil has been absorbed into the mixture, spray it off with a hose. Then, to the gallon of warm water, add a few drops of liquid soap.

Pour the water over the area slowly. Scrub the area with a wire brush in mild circular strokes. Continue scrubbing and adding water until the water is gone. To eliminate any residue, spray the surface with a hose. Using cloths, gently blot the affected area.

Now that you know how to remove oil stains from your driveway, you can rest assured that your driveway will not be permanently damaged if your car leaks or if you spill oil during an oil change.

You can successfully erase any oil stain that is marring the appearance of your driveway with a few easy and affordable items and a little elbow grease.

Does spilled diesel evaporate?

The most common type of diesel fuel is a light, refined petroleum product. Small diesel spills normally evaporate and dissipate in a day or less. Even in cold water, this is especially true for normal spills from a fishing vessel (500-5,000 liters).
