The efficacy of vegetable oil as an embellisher of porous surfaces has been investigated. Two different porous surfaces have been selected and, in each surface, five dissimilar oils with viscosity differences have been poured on them, using two contrasted volumes of oil. The effects of each oil on the surfaces and its efficiency to eliminate the saline efflorescences have been studied. It has been determined which oil was the most effective to leave the floor more embellished, after a previous explanation of what an embellished floor was. Subsequently, the results with olive oils have been compared to a professional product to clean porous floors, and it has been determined which one gives better results and which one is less expensive. The relative viscosity of the oils used has been found, and it has been related to the efficacy of the oils to eliminate the efflorescences and to embellish the surfaces. Finally, it has been concluded that all the oils used have eliminated the eflorescences, and that the best oil to embellish these surfaces is the olive oil, easier to use and more economical than the professional product. Moreover, it has been concluded that the more viscous an oil is, the more efficacious to embellish the surfaces it will be ​
