bro i would re-watch your choice of reagent pick alcl3 - i was googling all internet and future4200 across, and it all shatters when the god itself (hi rog), says that almost none of cleaning methods relatively work, and even says he’s done with alcl3 sop. 
Big problem is after-quench. Cl-THC (chlorinated thc), and aluminum micro-(almost-nano) size fraction.
Chlorinated THC - can be removed via My first try in converting CBDP to THCP - #66 by Roguelab
Aluminum with with activated carbon CRC column. Or just column i guess
Carbon is not for Chlorine
I mean, after that i didn’t need to be told twice. It’s better to use different reagent i think\ or i guess.
I heard here and there that there’s some good ways to clean it. And that people somehow do manage to clean their stuff with questionable by Masters words methods, like carbon column.
But when i ask for details on how they do it, and would it even work - they ask for money to “guide u”.
Honestly it’s not enough informed method - like. Almost any other methods - can be easily quenched without hard access reagent. Like… This potasium. That is used in…
Some high tier stuff idk
