Review on 🔥 Effective Heavy Duty Degreaser: Spray Nine 22705 Grez-Off - 5 Gallon Size by John Warren

This product was recommended to me by my brother who runs a large apartment building. I was amazed at the condition of my laundry room floor after our old oil boiler was removed and I found thick oil covering the floor where a much larger block was standing. This spray worked like magic as you can see in the picture! I used a flat sponge and brush to make small grooves in the concrete. I had to change the water in the flush bucket 1000 times but with this spray and tools it washed out easily. It's a bit strong and I didn't have good ventilation, but still bearable and not a bad smell at all. I highly recommend it for things like greasy garage floors!
