Empty and separate permitted parts
Remove leftover contents and disassemble only components that the manufacturer says are removable. Do not force valves, seals or narrow openings, which can stretch or tear.
Wash with a compatible method
Use warm water and a mild dishwashing product only if the bottle instructions permit it. A suitable soft brush may help reach the interior; avoid sharp objects and abrasive pads. Follow the maker's directions for food, cosmetic or toiletry use.
Rinse and dry all parts fully
Rinse away product residue and allow the bottle body, cap, valve and seals to dry completely before reassembly or storage. Trapped moisture or residue can remain in narrow fittings.
Check condition before reuse
Inspect for tears, tackiness, persistent odour, discolouration or a damaged seal. Replace a compromised item and do not assume boiling, microwaving, freezing or dishwasher cleaning is safe unless explicitly permitted by its maker.
