Soaking your retainers in hot water can cause them to melt. Direct sunlight and exposure to extreme heat can also cause your retainers to break. Do not leave your retainers in a hot car or in the sun if they are not in a case where they need to be cleaned regularly. Exposure to these two elements may also cause them to soften and melt. Here are some tips to help your retainers last longer.

What Temperature Do Retainers Melt At?

You can use a solution of water and vinegar to clean your retainer. Although vinegar has a strong odor, this cheap cleaning agent works to remove the white plaque from your retainer. The hot water can also cause your retainer to melt, deforming it. Be sure to follow the instructions on your retainer’s packaging to avoid causing additional damage. If you don’t have a glass bowl, you can use a plastic one. You should fill the bowl completely with vinegar, including all of the retainer’s parts.

If the retainer is in bad condition, you can try soaking it in hydrogen peroxide or baking soda. It will clean the retainer by removing the yellow stain and crusty buildup.
