6. Maintenance

To keep your ESR Essential Zero Clear Case in optimal condition:

• Cleaning: Wipe the case regularly with a soft, damp cloth. For stubborn marks, a small amount of mild soap can be used. Avoid harsh chemicals or abrasive materials, as these can damage the case's finish or clarity.
• Storage: When not in use, store the case in a cool, dry place away from direct sunlight to prolong its lifespan and maintain its yellowing-resistant properties.
• Inspection: Periodically inspect the case for any signs of wear or damage. A damaged case may not provide adequate protection.

7. Troubleshooting

Issue: Case appears to be yellowing.

Solution: While the case is made with yellowing-resistant TPU, prolonged exposure to UV light and certain chemicals can accelerate discoloration. Ensure proper storage and cleaning as per the maintenance section. If yellowing occurs prematurely, contact customer support.

Issue: Case does not fit correctly or buttons are stiff.

Solution: Double-check that you have the correct case model for your iPhone (SE 2020/2022, 8, or 7). Ensure the phone is fully seated within the case and all edges are properly aligned. If the issue persists, the case may be defective; contact customer support.

Issue: "Wet look" or air bubbles on the back of the phone.

Solution: The ESR Essential Zero case features a microdot pattern designed to prevent this. If you observe a "wet look," remove the case, clean both the phone and the inside of the case, and re-install carefully. Ensure no moisture is trapped between the phone and case.
