For The ProsTest ResultsThe Real World TestExperimentA wood floor was repeatedly cleaned with Murphy® Oil Soap and then recoated by an independent contractor. WoodAn oak parquet floor made by a leading manufacturer, with factory-applied polyurethane. Test MethodMurphy's® was diluted in a gallon of water at two different concentrations: 1/4 cup, as directed in label instructions; and a full cup, four times the recommended usage. The floor was then professionally recoated. Surface was roughed up with 100-mesh screen and recoated with a leading water-based polyurethane. ResultsThe polyurethane adhered to all areas of the floor cleaned with Murphy's — even areas cleaned at four times the recommended concentration level. The Soak TestExperimentWood was left to soak in Murphy® Oil Soap, then recoated. WoodTwo types of red strip oak: one sanded smooth and used raw, the other sanded and finished with two coats of polyurethane. Test MethodMurphy's was diluted in a gallon of water at three different concentrations: 1/4 cup as directed in label instructions; 1/2 cup, and 8 cups, 32 times the recommended usage! Wood was soaked in each of the three concentrations for two to 24 hours, and allowed to dry without rinsing. The wood was then recoated with oil-based and water-based polyurethane from leading manufacturers of both professional — and consumer — grade coatings. The raw wood was coated without sanding, screened, then coated a second time. The coated wood was screened with 100 mesh and then recoated. ResultsAll the polyurethane coatings adhered to all the surfaces — even those soaked in 32 times the recommended concentration level of Murphy® Oil Soap. The Residue TestExperimentUsing sophisticated laboratory techniques, surfaces were examined for any trace of residue left from cleanings of Murphy® Oil Soap. WoodSamples of typical finished wood. Test MethodMurphy's was diluted in a gallon of water at two different concentrations: 1/4 cup, as directed in label instructions; and 1/2 cup. Three measurement techniques were used: scanning electron microscopy, electron spectroscopy for chemical analysis, and Fourier transform infrared spectroscopy. ResultsNo residue was detected from cleanings with Murphy's, not even in microscopic trace amounts. NWFA Floor of the Year Winners recommend Murphy® Oil SoapMurphy® Oil Soap is oil-freeAlthough vegetable oil is one of the raw materials used to make Murphy's®, all the oil is processed into a gentle, natural soap. Murphy's is safe on wood floorsBecause Murphy's contains no oil or oil waxes, it leaves no residue behind when used as directed. Rinsing is not necessary. Murphy's is free of harsh chemicalsUnlike some cleaners on the market, Murphy's contains no ammonia or bleach. Murphy's is a non-abrasive soap cleaner that gently removes dirt and grime. |
