We recommend Fila Cleaner for your sandstone natural stone flooring. It is a mild soap cleanser with a balanced composition of natural and synthetic cleansing agents, supplemented with effective aftercare components.
For additional protection and sheen Fila Satin can be used. Fila Satin can be added to water to maintain the top finish.
Any stubborn marks can be removed with Fila PS87, an alkaline combination cleaner with a very broad range of actions.
