Ok, First try to clean it as much as possible before you you prepare to operate and pull em apart. Be ready to catch either piece if it happens to come out while cleaning it. Keep your shit clean in the future so this doesnt happen, also make sure both joints are dry before connecting. Clean it by running hot water through it, then using iso alcohol and rinsing. Let it cool down so the glass constricts again. edit: I see you got it out, just take my advice for the future
