To clean a copper bottle from inside: (1) squeeze 1 lemon + add 1 tbsp salt inside the bottle, (2) add warm water half-full, (3) close and shake for 30–60 seconds, (4) empty and rinse well with plain water. Do this weekly. The citric acid + salt gently removes copper tarnish without damaging the metal. Never use dish soap on the inside — it leaves residue that interferes with copper properties. Never use steel scrubbers or bleach — they damage the copper.
