Pressure barrel stained line

[Paul Roberts]

I have a pressure barrel as well as some cornys. I've just finished a brew in the PB and am cleaning it out but the line for the float is stained.
I have used Vwp and plenty of hot water but this is still stained. Presume this is never going to to be clear like my beer lines to the corny?

Oxi cleaner non perfumed will do the job. Soak it for 24 hours.

Or some PBW or your homemade version as well.

Caustic is very good but much more dangerous.

Did 2 of mine with oxi yesterday, 5L of warm ish water then filled to the brim for 24 hours whiter than white today, a good rinse and good to go
