Aluminum water bottles, popular with people wanting to avoid plastic and also with outdoor lovers, are often long with small openings. Because of the design, they are difficult to clean thoroughly. If they are put in a dishwasher, the steam may not reach and sterilize the bottom of the bottle. However, there are a few options for removing mold, stains, or other unwanted dirt from your bottle.
Fill your aluminum water bottle with warm water, and add one SIGG cleaning tablet (20 biodegradable tablets come in a bottle for about $8) or one or more effervescent denture cleaner tablets, such as Efferdent Anti-Bacterial Denture Cleanser (prices and number of tablets vary), into your bottle.
Allow the tablets to sit for the time directed on the bottle. The SIGG tablets should be left in for 30 minutes to leave a fresh, minty smell in the bottle. You may need more than one effervescent denture tablets, depending on how large your bottle is. Leave the solution in the bottle for at least 15 minutes or as long as directed on the product's bottle.
Empty the water bottle and fill it with dish soap and hot water. If there are really tough stains and/or mold, you can use a long brush to scrub the hard to reach areas of the bottle. Or, you can mix a cup of uncooked rice in with the dish soap and water and shake the bottle vigorously.
Rinse your bottle with fresh water.
Let your bottle air dry.
- Avoid putting anything other than water in your bottle, and you won't have to wash it as often or as vigorously.
