When you have installed a new unsanded spruce or pine floor, you can soap scrub the floor a few times before you put it into use to more quickly get the durable surface that soap scrubbing provides. The floor is also bleached by the soap each time it is scrubbed, which makes white pigment, lye or other “cheating methods” unnecessary. Soap scrub about 5 times (if you can!) and use a higher concentration of soap, at least 5 dl per 10 l of cold water. Wait about 1 day between scrubbings so that the floor has time to dry properly.
