How to use your copper bottle
A 10-second ritual and a few simple rules. That's all it takes to enjoy your bottle for years.

The daily ritual
Four steps, every day

Do's and don'ts
Do
- Use plain, still water, cold or room temperature
- Refill with fresh water every day
- Hand wash with warm water
- Air-dry with the cap off
- Clean with lemon and salt every 1–2 weeks
Don't
- Lemon water, juice, sparkling water, coffee, tea or milk
- Hot drinks
- The dishwasher or freezer
- Leave water standing for days
- Bleach or harsh scouring pads
Why plain water only? Acidic, fizzy or hot drinks draw much more copper into the drink. US food-safety guidance (the FDA Food Code) advises against copper contact with acidic foods.
Cleaning
Bring back the shine in 30 seconds
Real copper darkens naturally over time, like an old penny. That's how you know it's real. When you want the shine back:
- Cut a lemon in half and dip it in salt.
- Rub it over the outside of the bottle.
- For the inside, add a squeeze of lemon juice and a spoon of salt with a little water, close the cap and shake.
- Rinse very well with plain water, then dry with the cap off.
Some people love the darker look and leave it. Either way, it's normal.

Good to know
Common questions about care
Rinse it with warm water and let it dry with the cap off. That's it. You can also give it a lemon-and-salt clean if you like.
No. Air and water naturally darken copper. It's a surface change, not damage, and it's how you know it's real copper. Lemon and salt restore the shine.
Green usually means the bottle was left wet or had something acidic in it. Clean it with lemon and salt, rinse very well, dry it with the cap off and go back to plain water only.
Yes. Just keep it to plain water and give it a rinse at the end of the day.
No. It isn't insulated, so your water will slowly reach room temperature.
Who should check first
If you have Wilson's disease, or a liver or kidney condition, ask your doctor before using a copper bottle. PlainWell bottles are designed for adult use.
