I Waxed The Badger.
Fair point if one used some harsh stuff near daily and did not do a good job of cleaning the brush.Yes, true, I can totally agree with that.
My example happened within minutes with 190g/Lt, if I were to dilute that to 0.5g/Lt then rub it on my face and wash it off within 10 minutes but let it accumulate in my brush for twelve months? Deep down in that knot the hair is jambed together.
Human hair Depilatory creams etc eat hair, but only eat skin if left on too long? A case of some things are ok for certain times at certain concentrations.
