I recently installed laminated floors in my home. We love the ease of cleaning until my cat threw up on the floor. The accident happened the night before so most of the vomit had dried. I immediately cleaned up the mess with lukewarm water. After cleaning I have noticed that their is a stain left on the floor, about the size of two hands. How can I get this stain off of the floor without harming the floor? Any suggestions would be appreciated.
