Is BLC a substitute for BTF?

I am a 74 year old who generally frequents the gun forums as I shoot targets for a hobby. My eyes are getting too bad to see the sight picture any more. Thus I need a new hobby.
I’ve decided to brew up some hard cider.  As a newbie my supply of BTF iodophor was becoming depleted.
I ordered a bunch of supplies from one of the brew supply houses. One of the items I ordered was idophor.
What the supplier sent me was BLC (beer line cleaner).  It has a dilution rate totally different from idophor.
Did they just screw up the order or is the beer line cleaner supposed to be a substitute??  I’m so new at this that I don’t know.  I await your help. My 1 gallon of cider has been bubbling the air lock for 8 days.  Thanks for the help.

No, not at all a substitute. BLC is a caustic cleaner, BTF Iodophor is a sanitizer. Be very careful with the BLC if you do keep it; it’s extremely corrosive, especially undiluted.

a10t2: Thanks a million.  I’m gonna ring em’ up soon and complain.  They made the mistake, not me.
