The Concentrated Soap Method

You could use a concentrated washing soap at full strength to remove old oil stains from your garage. You just have to be careful so that the vapors do not get into your eyes. It is a great way to clean oil from the epoxy garage floor. Here is how you go about it:

Put some of the concentrated soap on the oil stain and let it soak for a while. You then scrub the old oil stain with the concentrated soap as hard as you can with a stiff brush, preferably a tub brush. After doing this, rinse the spot that you have been scrubbing with a hose. Set the pressure high so that the stream is strong enough. After about a minute or two, check to see if the stain is gone. If it is still there, repeat the process until you are satisfied with the outcome.

The Cat Litter Method

Ensure that it covers the area with the oil stain and try to grind it into the oil stain. Then you leave the oil for anything between an hour to several hours (even overnight), depending on how old the oil stain is. You then get rid of the litter after it has stayed for a while.

 Have a go at the oil stain using concentrated liquid soap and a stiff brush. Be generous with your application of the soap. Then rinse the area with a strong stream. Check for the oil stain and repeat where necessary.

 The TSP Method

TSP is short for Trisodium phosphate. Before using this chemical, ensure that you use eye protection and rubber gloves. Start by adding a cup of TSP into a gallon of hot water. You then pour some of the diluted TSP on the oil stain and let it soak for between 20 to 30 minutes. Use a stiff brush to scrub the area for a while after which you rinse the mixture. Repeat the process until you are satisfied with the outcome.

The Bioremediation Method

This is an eco-friendly method that involves using micro-organisms as oil stain removers to remove stubborn oil stains. It might take longer than the other methods, but it is arguably the most effortless method since there is no need to exert energy scrubbing the oil stain. It is one of the best ways to remove oil stains from concrete floors.

Use a pump sprayer to apply the microbial oil stain remover. This remover often comes in powder form and often requires a dash of moisture to activate the micro-organisms. Allow the solution time to absorb the oil and do its magic. Depending on how old the stain is, you might let it rest for any time between 24 hours to a week.

After the solution has absorbed the oil, sweep it away, then wash the area with soap and water. This method is so effective that the most time you might be required to apply the solution is twice.

The Concrete Degreaser Method

This method is also best suited for old oil stains that have defied other methods. The trick is to use the right stain remover. Here is one of the tips on how to remove old oil stains from concrete:

Use hot water to wet the affected area. Make a concentrated solution of the degreaser, which you then pour directly on the stain. After allowing the degreaser to soak for a few minutes(at least 5minutes), begin to scrub the area as hard as you can. Ensure that the degreaser does not dry while you are scrubbing it. Apply more degreaser if need be. After scrubbing for a while, sweep up the mixture, then rinse the area.
