i swear by mr clean magic erasers... they work on everything! follow up by thoroughly mopping with special wood floor cleaner (they almost always smell like orange), and they leave the floor beautiful and glossy. now, if its not real hardwood and that fake stuff, you can mop it with diluted mr clean or any regular, bleach free cleaner. if youre nervous about the magic eraser, test a small spot on a concealed area first... but ive never had a problem with it!! good luck!
