Wood reacts poorly to sudden or extreme changes in room temperature and humidity. Ideally, to help avoid problems, it’s best to keep wooden items in the most consistent environment possible.
In an ideal environment, avoid placing wood items near a radiator or in direct sunlight near glass doors or large windows. A humidifier can help normalize room humidity so that the wood does not dry out and crack during winter months. Rooms that create large amounts of steam and humidity such as a bathroom with a shower should be avoided.
Cleaning is recommended using a lightly dampened cloth dipped in lukewarm water. Wipe off any dirt and debris, and dry with a soft dry cloth. I recommend that you not use any off-the-shelf cleaning products. The solvents in these can remove the finish and irreversibly bleach the wood. Clean up spills immediately using a damp cloth and then with a dry cloth to minimize the potential of the liquid and debris penetrating the wood.
The wood is finished with boiled linseed oil. As a natural product, over time, the finish may fade and you may want to re-apply a finish of oil. Feel to reach out to me for any questions or seek the advice of your local woodworking or furnature finishing professional.
Avoid touching the paper shade as it may leave marks or creases that may not be removable. Instead, for Table and Floor Lamps, it's recommended to lift or adjust the shade from the wood rim by gently pinching your fingers on either side of the wood rim and paper shade to move it. Sconces should not be handled by the wood rim or the paper shade, but instead handled by the solid wood backing or any of the brass parts.
Like wood, the lampshade may react poorly to sudden or extreme changes in room temperature. Cleaning is not recommended; however you may wipe off any dirt and debris with a soft dry cloth. I recommend that you not use any off-the-shelf cleaning products, such as furniture polish or sheen agents. The solvents in these can remove the finish and damage the shade.
It is recommended to keep/store the cylinder the lampshade was mailed in to protect the shade should you need to move in the future.
