Hi, I'm Ann Myrick, and today I'm going to show you how to clean polyurethane coated hardwood floors. The first thing that you want to do is you want to be sure to sweep your floor really well. And the reason you want to sweep first is because you don't want to have rocks, dust, dirt on your floor, and you're putting pressure on your sponge with the dirt underneath and it scratches the floor even more. So, first you want to really sweep your polyurethane coated floor well, and then you want to come back with a solution of warm water and a oil soap. I'm using Murphy's soap, but there are several products out there. You just want to be sure when you are dealing with a specific type of floor, you want to be sure that you're using the right product. So, I am going to put probably about a fourth, it doesn't have to be exact, but about a fourth of a cup in my bucket. I already have a little bit in my bucket, so I just added a little bit more, and then I am going to pump my mop up and down, just to mix it up really well. You want to wring, this is just a regular sponge mop, but you want to ring it out very well, and then start on the side, in just a back and forth motion. Let me hook this mop so it doesn't scratch, back and forth motion. You want to cover your area with the water and Murphy oil, and then you want to go back with clean, clear water, and rinse. Same type of motion, but you want to go back and rinse it well, and then once you've mixed the total floor, I would not want to leave standing water on the floor, so then you just want to go back, I just go back and scooch. And this way it buffs the floor out, dries it and buffs it. This is Ann Myrick, and that is how to clean a polyurethane coated floor.
