If the floor is still not clean, or if it seems greasy or sticky, change it to warm, slightly soapy water to help dissolve the dirt. You may need this method especially near the kitchen stove. Wipe off any soap residue with a second cloth moistened only with water. Using folded rags allows you to fold them back to reveal clean areas, saving you from having to get up and down as often.

No, you can see where years of washing or cleaning have left the dirt in areas that were too difficult to clean properly. After sweeping, the next step was to use their floor cleaning spray, simply going around the room spraying it on the floor and then with the mop (with the cleaning pad on). Especially since it's been a long time since you last cleaned the floor thoroughly, working this way will allow you to see what's going on and will help you adjust the amount of cleaning in the different areas where you find the most dirt.
