There are several methods for soap scrubbing floors, depending on the type of linseed soap used. We recommend using a strongly alkaline soap specifically designed for floor scrubbing, such as our floor soap from Selder & Co. The soap is applied undiluted until the floor no longer absorbs it. Once the surface is saturated, any excess soap is removed. While a scrubbing machine can make the process easier, it’s not necessary—cold water and a regular mop work just fine!
The dried soap forms a hard soap layer within the surface structure of the wood, adding durability and making it resistant to dirt. When mopping with cold water, some of the soap dissolves, acting as a cleaning agent. A soap treatment lasts for approximately 50 moppings with cold water before it’s leached out and needs replenishing. You’ll know it’s time when dirt starts sticking to the surface. Over time, the floor will develop a beautifully bleached appearance from regular mopping. Spruce floors usually become lighter than pine floors.
