Troubleshooting
If you encounter issues with your SOS Intense Heating Patches, consider the following:
- Patch not adhering properly: Ensure the clothing surface is clean and dry. The adhesive is designed for fabric, not direct skin contact. If the patch is applied to very thin or delicate fabric, it might not hold as firmly.
- Patch not heating sufficiently: The patch activates upon exposure to air. Ensure the sachet was opened correctly and the patch was exposed to air for a few minutes. If stored improperly (e.g., in a humid environment), its effectiveness might be reduced.
- Patch feels too hot: Immediately remove the patch if it causes discomfort or feels excessively hot. Ensure it is applied over clothing and not directly on the skin, and that there is no pressure or tight clothing over it.
