The airflow on my vape used to be so good but now its clogged up or something. I gave it a few soaks in alcohol and water and it hasnt been fixed. I asked on Reddit but they all said just clean it which isnt working. I did notice though what the airflow only gets bad when i put a coil in it, whether clapton, ni200,rda. Without a coil its better but its still doesnt pull like it used to, even with a coil when i first got it. Can anybody help?
