To clean outdoor wooden floors and decking, dissolve a medium solution of Soda Crystals or add Liquid Soap to hot water and mop as usual. To prepare wooden flooring for varnishing or painting, make sure that all debris and flakes are removed and mop with a strong Soda Crystals solution. Indoor wooden and laminate flooring can be cleaned with Soap Flakes or liquid Soap. Rinse thoroughly afterwards to remove the soap suds.
