bong hits once or twice and completely clogs itself

i don’t understand. i opened this bad boy as an early christmas present last night and smoked a bowl or two. it immediately clogged itself, and i spent a while working through some hot water and isopropyl alcohol. it finally started hitting like a dream again… for another handful of hits. it’s almost completely clogged again and i’m loosing my mind over here. please: what can do i to save this from being a forever display piece?
