Step 2: Remove the Wide Mouth Lid

The spout, gasket, cap, and straw are all separate components on most Hydro Flask wide mouth lids. Begin by carefully disassembling the lid. Unscrew the cap, remove the gasket, and detach the straw (if required) according on your model. This disassembly will allow you to completely clean each component and eliminate any hidden pockets of filth.

Step 3: Rinse the Lid Parts

After disassembling the cover, clean each component under warm running water. This first rinse will get rid of any loose particles or leftover liquids. Pay special attention to difficult-to-reach locations where residue can accumulate, such as the threads and inside sections of the cap.

Step 4: Soak the Lid Components

To remove stubborn stains or odours, make a cleaning solution in a bowl or sink using mild dish soap and warm water. Soak the lid components in the soapy water for approximately 30 minutes. This soaking will aid in the loosening and dissolving of any difficult leftovers, making them easier to remove afterwards.

Step 5: Clean the Lid Components

After soaking, gently cleanse each component with a soft-bristle brush or a bottle brush. Pay close attention to the internal and exterior surfaces, as well as the threads. To clean the gasket and small crevices, use a toothbrush or Q-tip to reach those difficult-to-reach regions. Keep in mind to be gentle in order to avoid harming any delicate portions.

Step 6: Use Baking Soda to Remove Stains

Baking soda can work wonders for stubborn stains or lingering odours. Sprinkle a little amount of baking soda on the damaged lid components. Create a paste with the soft-bristle brush or toothbrush by gently scrubbing the baking soda with a few drops of water. Allow the paste to stay on the stains for a few minutes before thoroughly washing them off.

Step 7: Use white vinegar to combat mould or mildew

White vinegar is a good natural treatment for mould and mildew. Combine equal parts white vinegar and warm water in a dish or sink. Soak the affected lid components in the solution for approximately 1 hour. The vinegar’s acidity will aid in the removal of mould and the killing of bacteria. After soaking, use the soft-bristle brush to scrape away the residue before rinsing with water.

Step 8: Thoroughly rinse and dry

After cleaning each component, rinse it under running water to eliminate any remaining cleaning solution or dirt. Make certain that no soap, vinegar, or baking soda residue remains. After cleaning, use a clean cloth or paper towel to pat dry the lid components.

Step 9: Replace the Lid

Reassemble the lid once all of the components are clean and dry. To prevent leaks, ensure that each element is properly fitted and the gasket is properly seated.

Step 10: Finishing Touches for Added Shine (Optional)

To add lustre, lightly polish the lid components using a microfiber cloth. This step is absolutely optional, however, it can improve the look of your Hydro Flask wide mouth lid.

Alternative Cleaning Methods for Your Hydro Flask Wide Mouth Lid

There are various efficient solutions to explore if you’re seeking for alternate ways to clean your Hydro Flask wide mouth lid. While the typical soap and water procedure is effective, these options may be more suitable for your preferences or available resources. Here are the top five alternate cleaning options for your Hydro Flask wide mouth lid:

Scrub with Lemon and Salt

Try a lemon and salt scrub for a natural and eco-friendly cleaning solution. Cut a lemon in half and coat the exposed side with table salt. Scrub the internal and exterior surfaces of the lid components gently with the lemon-salt combination.

When vinegar and baking soda are combined, they form a powerful cleaning solution that can remove even the most stubborn stains and odours.
