help cleaning slide on bong!!

so ive got this pink illadelph and i managed to clean it to look like new with alcohol and rice. I cleaned the inside and pipe part of the slide but there seems to be a double layer that has a ton of resin in it.

I tried boiling it, soaking it in alcohol, and us]ing salt with hot water and alcohol to try to remove it.

Please help!

I'm not sure, but niiiice silly bands
I have dinosaur ones.

turn it upside down

cover the bowl with your thumb

pour in a GOOD amount of salt

fill it up 4/5ths the way and leave 1/5th of air


SHAKE vigorously, swoosh the salt over the resin


now congratulations on your sparkly piece


You may need to get in there with q tip (tip soaked in alcohol) to get anything that remains
