Residue after cleaning cornie with soda crystals

[mdex]

Evening,

I have just cleaned my cornie with soda crystal and am going to sterilise with videne but after cleaning there was a brown residue or 'scum' around the inside of the cornie?

Gave it a quick rinse with boiling water but what is it? Left over cola?

ive had this when i havent used a keg for a while, I just soak in soda crystals then wipe it off with some kitchen towel , just remember no tto panic when it feels like your arm is stuck in the keg

Yeah only panic when your sure your arm is stuck in the keg

but then remind yourself how much more embarrassing it would be if you had your head stuck in the keg

Nothing like getting the last remains from the keg

Its now been cleaned, sanitised and filled!

Can't wait to try it.
