Some good hardwood floor cleaners are Bona, Libman, Pledge and Murphy's Oil Soap, according to Good Housekeeping and About.com. Both sources cited Bona as a top choice because it works quickly, and floor installers recommend it. It has a trigger bottle for easy spot cleaning.
Libman is less expensive than many other floor cleaners. Libman’s concentrated form requires users to add it to water prior to use. Pledge comes in a squeeze bottle that spreads the cleanser quickly. It effectively removes substances that are stuck to hardwood floors.
Murphy's Oil Soap is favored by flooring manufacturers. The cleaner has been around a long time and cleans well but does not remove waxy build-up.
