It is recommended that you do not let the candle burn all the way to the bottom of the candlestick, as this can cause discolouration or damage to the varnish of your product. It is recommended that the candlesticks are used together with a base. The candlesticks cannot withstand being put in the dishwasher. Maintenance of brass and burnished cups: Brass and burnished cups are hand polished, which means their surfaces are not identical. Brass and copper are materials that develop patina, and the surface of the product will therefore change character over time. Use a damp cloth with dish soap to clean brass and browned cups. Remember to wipe off detergent residue after cleaning. After cleaning the candlestick in bronzed cups, the surface must be polished with silicone.
