Unsealed hardwood floors contain none of the polyurethane coating found in many types of hardwood flooring, giving the floor a more natural, rustic look that keeps the wood itself on display. This unsealed wood must be cleaned regularly just like any other type of wood floor, and when caring for unsealed wood you want to both get rid of build-up and give the wood a gentle oil treatment that keeps it looking its best.
Vacuum your unsealed hardwood each week; this will pull out any loose build-up.
Mix 1/4 cup white vinegar and 1 gallon warm water in a cleaning bucket to clean and disinfect.
Dip your mop in the vinegar water and squeeze it out with your hands.
Wipe the mop across the unsealed hardwood, re-dipping the mop when necessary. Allow the wood to air dry.
Drizzle enough linseed oil onto a cloth to saturate it slightly, and wipe along the grain of the unsealed wood. Continue across your entire floor.
Drizzle additional linseed oil onto a cleaning mop to saturate it slightly, wipe across your entire floor for an even application, and let the hardwood air dry.
