How to use a two-liter dispenser depends on which style you choose, mounted or siphon, but both are intended to be easy to use and easy to clean.
The bottled soda dispenser is designed so you no longer need to lift a soda bottle, and you'll only need one hand to pour yourself a drink. Although the bottle rests upside down in a stand for dispensing, fresh soda bottles are attached to the apparatus right side up for minimal spilling. In some models, placing a bottle in the dispenser is as simple as pressing a button to open the bottle holder, unscrewing the cap from the soda bottle and screwing the bottle's mouth into the dispenser's nozzle, and snapping the bottle holder back into a locked, upright position. Dispensing drinks is equally easy: Press a glass against the lever (or in some models, press down on the spigot) to start the soda flowing. Pull the glass away to stop.
Pressurized beverage dispensers come with a simple set of instructions. Replace the cap of a two-liter bottle with the actuator and lightly agitate the liquid to help fill the tube. That's it. With a push of a button on the head of the actuator, you're dispensing soda.
Cleanup is easy for both types. Two-liter dispensers can be rinsed -- and many have parts that are dishwasher safe -- to remove any sticky residue or to clean between different types of soda.
