What is a 5 gallon water jug?
A 5 gallon water jug is a large container that holds 5 gallons of water. It is typically made of plastic and has a screw-on cap or lid. 5 gallon water jugs are commonly used to store and transport drinking water, but they can also be used to store other liquids, such as juice, sports drinks, or even emergency supplies.
How to Clean a 5 Gallon Water Jug in 5 Easy Steps?

Step 1: Empty the Jug
The first step is to empty out any remaining water in the jug. Turn the jug upside down over the sink to empty it completely. Once empty, rinse the jug with water to remove any remaining droplets.
Step 2: Wash with Dish Soap and Water
Fill the jug about halfway with warm water and add a few drops of dish soap. Put the cap back on the jug and shake vigorously for 30 seconds to mix the soap and water. This will help break down any grease, dirt or grime on the interior surfaces.
Pour out the soapy water and rinse the jug thoroughly 2-3 times with clean water to remove all the soap. Be sure to rinse the cap as well.
Step 3: Clean with Baking Soda and Vinegar
For a deeper clean to remove built up grime and residue, make a DIY cleaning solution. Add 1⁄4 cup baking soda to the jug, then pour in 1 cup white vinegar. The chemical reaction between the baking soda and vinegar will cause fizzing and bubbling, which helps lift and dissolve mess.
Put the cap back on and shake the jug for about 30 seconds to distribute the cleaning solution. Let it sit for 5-10 minutes so the chemicals can work to break down any stubborn gunk.
Step 4: Scrub with Bottle Brush
Use a long narrow bottle brush suited for water jugs to scrub the interior surfaces. This helps remove any remaining grime and buildup. Make sure to scrub the bottom and all sides.
Remove the brush and rinse the jug thoroughly 2-3 times with clean water to flush out the cleaning solution.
Step 5: Sanitize with Bleach
For optimal sanitization, the final step is to sanitize the jug with bleach. Add 1 teaspoon of regular unscented bleach and fill the jug half full with water. Put the cap on and shake for 30 seconds to spread the sanitizing bleach mix.
Let it sit for at least 2 minutes before thoroughly rinsing with clean water. Allow to fully air dry with the cap off before refilling with drinking water.
Follow these steps on a weekly or biweekly basis to keep your 5 gallon water jug clean and hygienic.
