Wipe wooden candle holders with a soft, dry cloth to remove dust and minor wax buildup. For tougher wax residues, gently scrape with a plastic card, then rub any remaining spots with a cloth dampened with warm, soapy water. Avoid soaking the wood, as excess moisture can cause warping. For finished wood, polish occasionally with a natural, non-toxic wax to maintain its luster. If the candle holder has unfinished wood, avoid harsh cleaners, as they can stain. Clean regularly to prevent wax buildup and keep the holder in pristine condition.
