How to clean old hardwood floors

we had to have ours sanded and restrained. 3 bedrooms and a hall ran about $1800.

Vacuum thoroughly, then clean with Murphy's Oil Soap made for wood floors. It leaves a nice soft shine, not oily.

Use a good hardwood floor cleaner such as Murphy's Oil Soap. You might have to wash it a couple of times.

Once they're clean, it's decision time. You can have them sanded and stained professionally or you can rent a sander from the local big box for a fraction of the cost, or you can paint or use a new carpet to hide the wear and tear. Or you can rip up or you can cover up.

Sanding it yourself is a lot of work. I used a small belt sander and sanded a 12x20 room to bring back a beautiful maple hardwood floor. I didn't have any money and I didn't think I could handle a big sander, so for less than $100 excluding the sander, I did the entire floor and it looked beautiful.

Vacuum them really well then mop with a solution of clorox and water. If there's a strong odor use a strong solution.
