I cleaned my GLASS bong yesterday. I used the salt and rubbing alcohol method and it it completely spotless. The problem that I am having is that it still smells like salt and when i suck air through it I can taste the salt. I have tried everything, I ran hot water out of the faucet through it for about a half an hour. I have rinsed it thoroughly and have even tried rinsing it with mouthwash. I also tried soaking it in vinegar for about an hour. Nothing has worked. Do I need to soak it longer? Is there anything else I can use?
