Something has been so nasty for so long that even if you cleaned it, it would still be nasty.

Or something just happened that was so nasty, there can be no redemption.
1. I got this old cellphone, and I've cleaned it 4 times, but it still has bad breath smell and is greasy. It's PermaNast.

2. "I was brushing my teeth, and my toothbrush fell into the toilet instant PermaNast"

3. "can I borrow your keyboard? Bro, never mind there are fingernails in between the keys, PermaNasty ass"
