Begin by wiping the wet, old, caked-on oil stain with a microfiber rag. Then, spray Extreme Green™ Concrete Stain Pretreat directly onto the oil stain. Make sure to spray an ample amount evenly and let it dwell for approximately 15 to 30 seconds. This allows the enzymes to start breaking down the oil.
Next, take a microfiber rag and wipe up the pretreated area from the concrete surface. After the area is completely dry, apply Oil Away™ Waterless Concrete Cleaner to any remaining stain residue that may be trapped in the pores of the concrete. For those really tough stains you might be tackling, —a second application may be necessary.
Oil Away’s enzyme infused technology uses a time-driven process. This means the longer the product is on the oil stain the better it works. After application, just walk away! Let the enzymes do all the work.
