After pouring an appropriate amount of warm water into the basin, you can add a few drops of mild and non-irritating detergent, which can effectively break down grease and impurities while protecting the surface of the water bottle from corrosion.

Then, immerse the sports water bottle completely in warm water, and use a soft sponge or a special cleaning brush to gently wipe the inner and outer walls of the water bottle, paying special attention to the bottle mouth, bottle cap and other parts that are easy to hide dirt and dirt, to ensure that every corner can be thoroughly cleaned.

After completing the initial cleaning, rinse the water bottle thoroughly with clean water to ensure that there is no residual detergent. At this time, you can also add a small amount of lemon juice or white vinegar to the water, using its natural antibacterial and deodorizing properties to add a touch of fresh fragrance to the water bottle, while further eliminating any residual odors.

Finally, turn the kettle upside down to dry, or use a clean towel to gently absorb the moisture to prevent moisture from breeding bacteria inside.
