Frequently Asked Questons (FAQ)
Does it deteriorate over time?
While pure copper does oxidize and tarnish over time, our composite technology is resistant to these effects. It will patina, or slightly darken, over time. However, unlike traditional “Statue of Liberty” oxidation, this patina is not green and will not stain your hands or clothes. You do not need to keep it polished to keep it working, but we do support keeping it in good shape. Clean it often using a soft cloth — see "How do I care for my patina?" below for more.
How do I care for my patina?
Our copper alloy was designed to minimize “Statue of Liberty” oxidation. This means that your phone won’t turn green anytime soon. However, like fine leather, it will naturally patina over time. This means that your copper case will gradually darken, particularly on the areas you touch most.
At Aeris, we tend to leave our patinas to develop naturally and give a unique look to the case, like fine leather. If you would like to reverse the patina, here is a simple tutorial on how to return your case to its original state. There are many industrial materials that can also help, but we prefer to use common household products.
What you will need:
- Your case
- A lemon / lime (juice also works)
Step 1: Remove your device from its case.
Step 2: Place a small amount of salt directly onto the copper surface.
Step 3: Cut off a wedge of your chosen citrus.
Step 4: Scrub your case with the wedge. Attempt to cover it evenly and completely. You should start to see results within 30 seconds. Continue to scrub until you have reached the desired color.
Step 5: Thoroughly wash off the case with water, then dry.
That’s it! The copper will be just as effective as before, but now it’ll look like new.
To slow the patina process, store your phone in a cool, dry place as much as possible.
Does this case interfere with phone signal, contactless pay, and wireless charging?
Our design does not interfere with phone signal or contactless pay, and our case works with most wireless chargers.
What phone cases do you offer?
Please see our product pages for updated list of offerings.
Does copper make the case heavy?
