Should I clean or replace my bow hair before the first application of Baker’s?
Baker’s does not usually blend well with modern production rosins and so yes, it is important to start with new or well cleaned bow hair.
Often hair that has lost it’s ability to produce proper tone is not actually worn out, but just clogged with old rosin.
Instead of the expense of hair replacement we’d like you to first consider a proper cleaning, and the way to do this is with rubbing alcohol...not soap and water as some may suggest.
Pinine, which is what the base of most if not all rosins is, is not water soluble, and soap is an emollient not a degreaser, so all that soap and water can really do is thin out and spread the old rosin around.
This results in the filling in of the tiny irregularities in the horsehair, leaving in their place a flat surface which of course cannot create useable tone.
Many ppl because of this believe that their hair is clean after using soap and water, since it will no longer produce tone, however, the truth is often that the hair has only become clogged and too smooth to perform the grab-release action required to generate tone....try a cleaning first and save yourself some money.
