I don't leave reviews often but I just had to here. I have used about 6 bottles of this to maintain the floors beneath an industrial deep fryer over the last month and also once a week in routine mopping.. It is amazing stuff. Just follow the directions and an hour later it has eaten through a quarter inch of fryer oil. It is a bit pricey to use daily but even still worth it! Took me two months trying to find a product that you basically spray on (hard to reach areas) and just let it work. This company has some other interesting products that I haven't tried yet, but will.
