Sometimes, there can be some stubborn and semi-permanent kind of specks of dirt and spots that will take place to your laminate floor. Some of the common examples are- tough spots, oil spills, markers, paint, ink, tar or lipstick.
To deal with those kinds of diets, you need to recall our old cleaner friend- the acetone or nail polish. Take a small amount of it on a white, clean cloth. Now, wipe the area with water, and later with the acetone-rich cloth. It will come off surely.
