How do I fix my OtterBox?

Stretching is the most common failure of silicone and rubber cases. Thermal shrinkage can help repair the damaged cases. It is necessary to heat the case and then cool it quickly. This process may damage the case and cause permanent deformations. In addition, phone cases with significant stretching do not always get back to their original size.

A torn case can be sealed with superglue. Suitable any cyanoacrylate glue, such as Gorilla Super Glue Gel XL. You can also pick up any other glue you like on Amazon. Cyanoacrylate glue is suitable for bonding all types of materials: silicone, rubber, plastic, metal, ceramics, etc. Therefore, the glue can be used to join broken parts of the case or repair cracks.

Yellowed and darkened clear OtterBox cases can fix the bleaching process. Bleaching is also suitable for white cases.

Polishing can help remove scratches from the OtterBox plastic case. It is best to use a diamond polishing paste with a 0.25-0.1 micron grain size for polishing. Deep scratches can be repaired with adhesive.

10. Take the case out and dry it. The sudden change in temperature should shrink the case and make it smaller. If you were unable to fix the case, the case may not have heated up enough and you need to heat the water more. Also, the sheath may have worn down a lot and shrinkage is not helping.

How do I fix my rubber OtterBox case?

A stretched rubber OtterBox case can also be fixed by thermal shrinkage. Rubber has a higher thermal threshold than silicone. Therefore, the rubber case needs to be heated harder. Evaluate the risks before shrinking, as the process can deform and seriously damage the case.

To shrink the rubber case, do the following steps:

1. Remove the case from the phone. Also remove the plastic case if the phone case has two parts.

2. Wash the rubber case in clean water or soapy water.

3. Prepare a container of cold water. Add more ice to the water.

4. Boil the water.

5. Immerse the OtterBox rubber case in the boiling water.

6. Press the case down with a spoon or something else, because the case will float to the surface.

7. Hold the rubber case in the boiling water for a couple of minutes.

8. Then take the case out. If the case is deformed, then straighten the case. Get a towel or something else, as the case can leave burns on your skin.

9. Immerse the case in ice water. It is important to put a hot carrying case in cold water. Therefore, do not let the sheath cool down when you take the sheath out of the hot water.

10. It is important to lower the whole sheath into the cold water and hold for a few minutes until it cools completely. The case should not float to the surface. Therefore, put pressure on the case with the objects you have on hand. At the same time, you do not need to put pressure on the case itself, as it may cause unnecessary deformation.

11. Take the case out of the cold water and dry it.

12. Evaluate the result of thermal shrinkage. If shrinkage is not successful, you may need to keep the rubber case in hot water longer. Also keep in mind that shrinkage will not help if the case is badly worn and stretched.

How do I stop my Otterbox from stretching?

There are several factors that cause the Otterbo case to stretch. The main one is taking the phone case on and off frequently. A new case usually fits tightly to the phone. Therefore, to remove and put the case on the phone, many users stretch a little bit the case to install the phone. After each such procedure case stretches and increases by several millimeters in size. So there is no need to remove the case without a good reason.

Another reason for stretching the silicone and rubber case is heat. Under the influence of high temperature, the phone case deforms. In your hands or in a pocket of your clothes, the case does not get hot. But in a car or with a high load the case can get very hot. Therefore, do not put the phone on the dashboard of a car on a sunny day. Also do not use the phone in the heat, as well as at the same time to charge the phone. This is not safe for the phone battery, and also accelerates the deterioration of silicone and rubber case.

Another reason for the stretching of the case – ultraviolet light. Sunlight accelerates the natural wear and tear of the silicone and rubber case. So you should use your phone less often in the sun to slow down the natural wear and tear of the case. If you do not plan to use the case for some time – hide the case in a dark and cool place.
