Water marks on barn wood panelling make your once-rustic walls look an unsightly mess. Remove these marks or stains using one of several common household items. Barn wood panelling often contains cracks and creases, and it may be difficult to remove the marks if they overlap into these crevices. If you cannot get into the cracks with a cloth, swap it out for a sponge or cotton swab to apply the cleaning material.
Apply mayonnaise to the water marks.
Rub the mayonnaise into the marks with a soft cloth.
Allow the mayonnaise to sit on the marks for 12 hours.
Wipe the mayonnaise off with a damp cloth.
Dampen a soft, lint-free cloth.
Apply a small amount of a non-gel toothpaste to the cloth.
Rub the cloth and toothpaste on the water marks.
Rinse the residue with a damp cloth.
Dry with a clean cloth.
Apply mineral oil to the water mark.
Allow the mineral oil to sit overnight.
Check the stain. If it has become less noticeable, reapply mineral oil and allow it to sit overnight again. Continue applying until the stain is gone.
Test the alcohol in an inconspicuous area of the barn wood panelling. If an adverse reaction occurs, discontinue use.
Apply denatured alcohol to a cloth or sponge.
Rub the denatured alcohol into the water spots until it disappears.
If the water spot is still wet, use a hair dryer set on the lowest setting to dry the area. Drying the spot may get rid of the mark.
