Safe handling of used condoms

Hello everyone, I hope this topic isn't too strange, but many people share the feeling of material on their skin. Therefore, I hope it's okay if I post this topic here: I have a fetish for used condoms because it's hot to know that a hot cock was inside them. However, when you find used condoms in nature, they're often dirty, and you don't know if the contents are infectious (viruses, bacteria). And if the condom is a few days old, the latex is already white. Does anyone have any tried-and-tested tips on how to ideally clean such used condoms, make them non-infectious, and possibly salvage the contents? Wash the outside with water and shine a UV flashlight on them might help? Are there any online forums where people can share their experiences? Thank you very much.
