In a nut shell, yes. Some things to keep in mind. Iron and steel are different. If you use steel, make sure its good carbon steel, nothing with galvanizing or impurities, that is said to kind of ruin it. Its just like auqua fortis but instead of the harsh ( nitric?) acid, you are using vinegar. The vinegar breaksdown and carries the iron particals into the wood, the vinegar evaporates and whats theft is what you see. Its something I read about on American Longrifles. A guy by the name of LongJohn has done xtensive testing and writing about this. I just studied and experimented with what he has written. I think he actually has a degree in chemistry. In october, I started a new batch in a pickle jar using apple cider vinegar and wrought iron. Its still brewing. No one has said for sure but I think you need to let it cure for at least a month or two. I used some last winter for the first time on a restock, it had been brewing since 2014, I kind of forgot about it because I moved two states over in 15🙃 This is that stock, with the stain only and then after an oil finish.
