i got a call to clean a bar restaurant that has 2800 sq ft of tile,it is ceramic and very dirty grsy,i am wondering if i can get a brush for my mercury floor scrubber,all i have is the pad driver.so i am wondering if i can use a floor pad to agitate my product,and what product to use.can i use floor stripper (zep).or a degreaser.my normal procedure works well,but i want to really cut the grease because the tiles have little gouges in them that are full of grease
