The last thing you want when smoking your hookah is for your hose to taste like the last flavor that you smoked. Follow these easy step-by-step instructions to keep your hookah hose fresh and clean.
Before following these instructions, you must ensure that your hose is washable, such as the popular washable hose is the Nammor Hookah Hose.
Step One: Remove the mouthpiece and fill up the hose with water about halfway. You can also use water from a pitcher or water bottle if you would like.
Step Two: We have found that using a small amount of lemon juice mixed with the water is great for neutralizing odors, and provides a fresh taste to your hose. We do not recommend using any soap, such as dish soap. 
Step Three: Now you’re going to want to swish around the water/lemon juice mixture in your hose. Plug both ends of your hose with your thumbs to prevent any leaks, and swish the water around for about a minute. Pour the water back into the sink, and repeat the previous steps if necessary, depending on how dirty your hose is you might need to do this 2-3 times.
Step Four: Swing! After you have poured out the water into the sink, there will still be a small amount of moistiure that you will want to remove. The easiest way to remove the rest of the moisture is to head outside (for safety) and grab the hose in the middle, and swing it around by your side, this will force out any loose drops of moisture. This process should only take about a minute.
Step Five: After you have gotten all the moisture out of your hose from swinging it, blow through the hose one last time to ensure that you remove any loose liquid inside. The final step is to hang your hose over a doorknob, so that both ends are point down, letting any leftover moisture to drip out.
Once your hose is dry, it’s ready to be used with your hookah!
