Hi everyone hope you are good. I have bought a new piece called the basil bush tar catcher and it has a percolator inside it that you can remove. (you can pull all the pieces apart), my problem is that the percolator goes brown instantly after one hit , (after its just been cleaned spotless) and after 2 or maybe three hits more the percolator is so blocked at the top that the bong wont pull anymore. Thanks to anyone that can offer advice or help, thanks!
