Hey guys. I hope someone can help me here. I went to put clean water in my humidifier last night and I noticed something nasty was in it. I have no idea how long it’s been there either because I almost always fill it up with water at night beside my bed and it’s dark.
The gunk has a weird smell to it. Almost sour. I haven’t cleaned it yet because I’m not even sure the safest way to clean it out.
Here is an image of the inside of it. Any ideas what it is?
