We were painting a room with a spray and had some drop cloth issues. As a result, there is a thin layer of paint on part of the floor. Part of it is wiping up with a warm, wet rag fairly easily, but part of it is requiring some pretty heavy elbow grease along with a very wet rag to loosen up the tiny spots of paint for removal.
Since I'm already having to get the floor fairly wet with a rag (I am drying immediately afterwards with a towel) I'm wondering if it would hurt to use a water extractor. We have the heavy duty home version rug doctor which has pretty good suction power. My only concern is that it came with a warning not to use on hardwood floors, but this may just be CYA on the part of the manufacturer. As far as I know the unit doesn't actually heat the water, it just dispenses whatever I put in it.
