I hear people talk about using vinegar to clean their hardwood floors. It is a great inexpensive, eco-friendly cleaner for tile floors or other surfaces but not for hardwood. Vinegar is acidic and can cause discoloration and/or break down the finish. Stick to products that are recommended by the manufacturer such as Bona Hardwood Floor Cleaner, a Greenguard Certified Product. It is easy to use and will help protect the finish without leaving a dulling residue. For a light cleaning I just spray a little bit of the cleaner on a mop head, for more in depth cleaning just spray the floor and wipe up with a mop. It’s easy and painless. Just the way I like it!
