What are these, bugs!

I am a clean person that's why I have been freaking out about this I'm not sure what kind of bugs these are.. Their so small, it's almost hardly noticeable. I saw them first on this white/yellow bottle, it's my saline to clean my piercings anytime I saw them I would hold the saline bottle under running water until I didn't see anymore. I hadn't saw them on anything else, until last night RIGHT AFTER I put mouth wash into my mouth I saw it on that bottle. 😳😳 Help! What is it? How do I get rid of it??
