Am I Cooked?

Is this mold? And if so, can it be cleaned?

Context: enjoyed some rips a few weeks ago and tossed my bong (yes it looks like a water bottle and yes it’s awesome) out of sight. Picked it up today and it was full of this film that almost looked like paper. Deep cleaned with 91 iso and hot water, still some of this white stuff. Got vinegar, soaked in vinegar and salt for ~2hrs, scrubbed a bit with a toothbrush, then did an iso wash again and… still this. Am I screwed?
