At this part, I definitely think the temperature matters. Warm or hot water breaks down and melts the ingredients which would seem to help in washing them away, yes? I always pre-soak. My routine is to fill my sink with hot water. Then place my surabachi bowl that I use for lathering and the brush I am going to use, into the sink full of hot water. Then I let them heat up and soak while I am taking my shower. On a side note, I will say that both of my Simpson brushes are the "worst" ones that I use. They shed horribly and have done so since day one of my ownership.
@IAmTheJody I'll give you warm or hot during the rinse may get out more sludge. Seems logical. Cold seems to get out enough gunk that I haven't noticed any buildup.
I haven’t rinsed my brush in three years and it is just fine. It started as an experiment, now it is a way of life. After all it is just soap on it. I think most folks rinse and dry and that is just fine I don’t think it makes much difference, just do as you like.
