How "hot" hot water on a brush?
A beginners question, with regards to brushes and water temperature. The search function has been used, but please feel free to provide a link, if topic has already been discussed ad nauseam.
There is somewhat conflicting information between that which is found online, and the literature that came with my Thäter badger.
With plenty of outside references to "hot" water, for brush wetting/soaking, none seem to explain what could be considered "too hot". By too hot, meaning the kind of temps that certainly would destroy a brush over time.
The manufacturer recommends "warm".
My budding routine involves steamy hot tap water into a shaving bowl, followed by soaking the tip of brush for less than a minute. A shake or two, then hit the soap. After transfer of soap to brush, water is dumped from bowl, and a good slick lather is hence whipped.
To further elaborate on "hot", a finger can be dipped into bowl for about five seconds, until it starts to become uncomfortable. Not boiling, mind you, but definitely what I would call hot. While this method is about as unscientific as it gets, would appreciate an acceptable temperature range, or gut check, to avoid damage to brush.
