Here are some common mistakes people make when cleaning or maintaining their water bottles:

1. Not washing their stainlee steel water bottle regularly: It's important to wash your water bottle stainless steel after each use, especially if you're using it to store something other than water. If left unwashed, bacteria can build up and potentially cause health problems.

2.Not cleaning the cap and mouthpiece: The cap and mouthpiece of a water bottle can harbor bacteria and other germs, so it's important to clean them thoroughly, especially if you've been drinking something other than water.

3. Using harsh chemicals or abrasive materials to clean their coffee mug: Some people make the mistake of using harsh chemicals or abrasive materials like steel wool to clean their coffee cup, which can damage the sublimation tumbler and potentially leave harmful residue behind. It's best to use gentle cleaning solutions like soap and water, or a mixture of vinegar and water.

4. Not drying their thermos bottle properly: After cleaning your insulated water bottles, make sure to dry it thoroughly before using it again. Moisture can promote the growth of bacteria, so it's important to make sure the bottle is completely dry.

5. Not replacing their kids water bottle when necessary: Over time, water bottles can become scratched or damaged, which can make them more difficult to clean and potentially harbor bacteria. If your water bottle is showing signs of wear and tear, it may be time to replace it with a new one.
