What epoxy system was installed or are you planning to install? If you know what the product is and who made it, their tech services department can tell you how to properly clean the material.
I typically use a 5 to 1 solution of Simple Green and water with a standard mop on my Rust Oleum Professional floor. Acetone cleans up paint overspray with a little elbow grease. If caught early enough, fluid spills wipe up with paper towel.
