3 Easy Ways To Clean Your Copper Water Bottle

Copper water bottles have become increasingly popular in recent years. Many people use copper bottles to store and drink water due to the health benefits associated with copper. Copper is known to have antimicrobial properties that prevent the growth of mold, fungi, and bacteria in the water. Copper bottles also help to neutralize the pH of the water and remove any metallic taste.

However, it is important to clean your copper bottle regularly to remove any residue or oxidation that can build up over time. Here are some easy methods to clean both the outside and inside of your copper water bottle.

Why Do Copper Bottles Turn Black?

Copper bottles are known for their beautiful reddish-orange metallic shine. But over time, with use, you may notice your copper bottle starting to turn black or dark in spots. This blackening is caused by oxidation and the build-up of copper residue inside the bottle. While unsightly, it can be removed and prevented.

 There are two main reasons why a copper bottle slowly turns black:

• Oxidation: Copper naturally undergoes oxidation when exposed to air and liquids. This causes a black layer of copper oxide to form.
• Residue Build-up: Tiny bits of copper leach into the water over time. As water evaporates, this copper residue is left behind and clings to the interior surface, leading to black spots.

Supplies Needed

Before getting started, you will need to gather a few supplies:

•     Mild dish soap
•     Water
•     Bottle brush or old toothbrush
•     Lemon/lime juice or vinegar
•     Salt
•     Baking soda

Make sure you have these basic supplies ready before tackling the cleaning process.

How to Clean the Outside of a Copper Bottle

Here are some simple steps to clean the exterior of your copper bottle:

1. Rinse With Water

Rinse the outside of the bottle first with plain water to remove any initial dirt or debris. This will help loosen up some of the oxidation as well.

2. Use Dish Soap

Apply a small amount of mild dish soap to the outside of the bottle. Keep the soap away from the mouth opening to avoid getting soap in the interior.

3. Scrub With a Brush

Use a bottle brush or old toothbrush to gently scrub the outside of the bottle. Scrub any stubborn spots and work to remove stuck-on grime or oxidation.

4. Rinse Again

Once scrubbed, rinse the bottle thoroughly with clean water to remove all soap residue.

5. Dry Completely

Make sure you dry the outside of the bottle completely before moving on to cleaning the inside.

How to Clean the Inside of a Copper Bottle

Cleaning the interior of a copper water bottle takes a bit more work but can be done with common household ingredients. Here are some easy methods:

Vinegar Rinse

•     Fill the bottle about 1/4 full with undiluted white vinegar.
•     Cover the mouth of the bottle and shake vigorously for 30-60 seconds to coat the inside with vinegar.
•     Allow to sit for at least 15 minutes before rinsing. The acetic acid in vinegar will help dissolve mineral deposits and oxidation.
•     Rinse thoroughly until the vinegar smell dissipates.

Lemon/Lime Juice Scrub

•     Quarter a lemon or lime and squeeze the juice into the bottle. Sprinkle in some sea salt as well.
•     Cover and shake vigorously to scrub the inside.
•     Allow to sit for 10 minutes before rinsing thoroughly. The citric acid will help remove copper oxidation.

Baking Soda Cleaning

•     Fill about 1/3 of the bottle with warm water. Add 2 tbsp baking soda.
•     Cover the mouth and shake the bottle for a minute to create a cleaning solution.
•     Allow to sit for at least 30 minutes before rinsing thoroughly with water.

Bottle Brush Scrub

•     Use a long, narrow bottle brush to scrub the interior after trying one of the above solutions.
•     Scrub all sides of the interior and the cap as well.
•     Rinse thoroughly until the water runs clear.

Air Dry Upside Down

Once the inside is cleaned, be sure to air dry the bottle completely upside down. This will allow all remaining moisture to drain out to prevent mold growth.

Maintenance Tips

•     Clean your copper bottle at least once a week, depending on its use.
•     Allowing the bottle to air dry after each use can help prevent oxidation build-up.
•     Using a bottle cleansing tablet occasionally can also freshen up the interior.
•     Never put copper bottles in the dishwasher or use abrasive scouring pads.
•     Avoid keeping plain water sitting in the bottle for prolonged periods.
•     Re-clean and polish the exterior as needed to restore shine.

The Benefits of a Clean Copper Bottle

Taking the time to regularly clean your copper water bottle has many benefits: 

•     Removes oxidation and mineral deposits that can be unhealthy if ingested
•     Keeps the copper effectiveness high by removing residue build-up
•     Restores shine and maintain the appearance
•     Prevents mold, bacteria, and bad odours inside the bottle
•     Allows your water to retain its clean taste

Conclusion

Copper bottles need a little more care and cleaning than stainless steel or plastic bottles. But with the right techniques and regular cleaning, your copper bottle can remain oxidation-free and look brand new for longer. Properly caring for your copper bottle ensures you can keep enjoying the health benefits of storing your water in copper.
