To open a screw-cap bottle, firmly grip the bottle with one hand and twist the cap counter-clockwise with the other. If the cap is overturned or hardening, use a cloth or rubber glove to increase the grip. The wide rubber band wrapped around the cap can be divided to heat the band. To prevent contamination, inspect and clean the remains of any fragrance from the neck of the bottle.
