Badger hair is much like human hair, and vinegar rinses were quite common years and years ago. My mom is older and I remember her saying how her mom would have her children rinse their hair with vinegar rinse all the time. I feel comfortable at a 4 parts water to 1 part vinegar ratio, and to me it seems to help. It puts my mind to ease, and I feel confident in my method. I primarily employ this method with used brushes that I buy. I can't recall the last time I've felt a brush I've personally bought needed it. I've always felt the liquid soap for five minutes, rinse, and then 10 minute soak in the diluted vinegar rinse with a dash of glycerin has helped, however.
Rinsing that brush out well is the biggest thing. I'm a far cry better than previous users of old you would see portrayed in movies lathering up that brush in a mug and putting the brush away full of lather for its next run. That poses far more risk than the brief 10 minutes any brush of mine will ever experience with a diluted vinegar ratio, and any manufacturers I'm sure would be clawing their eyes out internally shouting, "NO NO NO NO!" Heck they might just let it out externally.. By no means does this need to be followed. I can't comment on doing it frequently as I don't need to and frankly wouldn't be inclined to do that. There's plenty of other means of cleaning the brush out there that can be employed that work well. For the rate at which I employ the rinse and how I feel it helps works for me, I'm happy!
