That is a good choice.I have a steam power wacher and thought about really attacking the big barrel and cleaning, using Oxyclean, Star San, etc.
Alternately, put a holding solution in the barrel and let it set a month. If the holding solution is funky after that, it saves wasting even a few gallons of wine.After all, life is a test and we can experiment. I would not put 30 gals of wine in them, but couls try it and see if the wine stored in for a few weeks turns funky. I have CO2 and argon gas to put in the big barrel.
Whoa!. That’s very cool. Never seen that one.
Odd that I don't know this off the top of my head. But to be fair, I've only been using barrels for 5 years and I keep 'em full, so it's not something I've done.What type of holding solution.
I used the holding solution Bryan listed on a couple leaking barrels. It worked fine and after waxing the leaks, I have two usable 10 gallon barrels.Odd that I don't know this off the top of my head.

I found several references that said:
For every liter of barrel volume, you will need to add 1 gram of citric acid and 2 grams of Potassium Metabisulfite.
I cannot recall why citric acid is specified. It must have properties different from tartaric.
You will need to top the barrel every 4-6 weeks, same as if it had wine in it. The amount of topup will depend on barrel size, ambient temperature, and relative humidity. On the plus side, assuming the barrel works out, you'll know what you need for topup wine.
Patience. Yes. I know. But....I used the holding solution Bryan listed on a couple leaking barrels. It worked fine and after waxing the leaks, I have two usable 10 gallon barrels.
Give them time to leach out the funk. 6 to 12 months at least. What do you have to lose but space and a few chemicals?
