If concrete gets too hot it explodes.

Well... I consider myself an expert in oil stain removal; I worked tirelessly at a Kroger Fuel Station with the attitude that my fuel station would be the cleanest in town. Behold, Kroger made it easy for me with the product Eximo. Eximo can be bought in larger quantities for cheaper, but here's the facts:

1. Eximo contains an enzyme that "eats" petroleum...then blows away...
2. Eximo blends into the concrete color...just use a little bit and sweep it in...
3. Eximo has the appearance of dry concrete.


At home, I would just sweep it into the stain and maybe cover it with a piece of cardboard (not necessary). Recheck in two days... you'll see its working...maybe sweep in a little more. With care, one square foot of oil stain can be treated with about one tablespoon of Eximo....

One of those "thank me laters"... Google "Eximo"

It works when the oil is already absorbed?

PPE may include a safety vest and cones.

I cannot find a video by anyone but the manufacturer.

It only shows someone sweeting a concrete-colored powder over stains, it doesn't show the product in action.

It is rated 3.9/5 on Amazon: https://www.amazon.com/EXIMO-Waterle.../dp/B00CHTDO5K and
4.2 on Walmart: https://www.walmart.com/ip/CAF-Outdo...unce/493358570

Yes, the video shown is fairly accurate. I used it daily and observed the progress. It will continue to work at oil that had been 'absorbed' into concrete. One cup should treat a "fully" oil stained concrete floor. (Most people will be treating a, say, 20sqft area...) Trust me, I had the cleanest concrete pad in town, hands down...
For cost, buy bigger packages...a 2.5 gallon bucket is about $150....much cheaper than wages, saves a lot of time....there are packages of various sizes. Remember, you sprinkle it on, sweep it in, and wait about a week . You can sweep more in if you wanted to.....

I have no affiliation with Eximo. I would sooner order a 32oz package than look for a mop/brush/soap.

Results from a FB friend using EXIMO after 5 days (its still working)

I would think the enzyme solution would be most effective, requires time and likely reapplication. Left over minute amounts of previous cleaners might unintentionally thwart that process.
When oil seeps into the microscopic cracks/crevices in concrete, no water-based detergents can penetrate past the initial contact surface enough, to prevent later the oil from migrating back to the surface and becoming once again visible.

I would like to explore for faster method on concrete an organic solvent like lacquer thinner or acetone liberally applied on very dry concrete, and left to dry, and minutes later, reapplied, and then ignited, the thinking being, it will penetrate the concrete, it will dissolve with the left-over oil and/or remanents, and the burning will draw/wick the visible oils/solids to the surface for removal. It will Not get hot enough to damage the concrete, as the heat will want to rise away from the concrete, and the duration will be less than a minute as it flashes off.

The subtle message above is dry concrete, as moisture in concrete is what causes most damage to concrete when heated above 212F which turns to steam and spalls the concrete.

New 4gpm pressure washer works pretty good at blowing oil stains.
