A wash bottle is a squeeze bottle with a nozzle, used to rinse various pieces of laboratory glassware, such as test tubes and round bottom flasks. Wash bottles using in laboratories. Wash bottles are sealed with a screw-top lid.
Wash the bottles in a hotel sink or public restroom. If you're prepared and have your dish soap and bottle brush with you, you can wash the bottles in any available sink.
