Thanks for the suggestion, @Langers.
Jon is right in how we expected this to be accounted for when we build the Cleaning and Maintence section of Breww, but I can see why some people might prefer to link these costs with the next batch the vessel is used with.
As this is essentially a duplicate of Connecting Cleaning/Maintenance with a batch, please can you vote for that thread and I’ll close this one. If there’s any other discussion needed, please post it on that thread too.
Cheers
