Herb, ever add glycerol to the mouth rinse you advocated for reed
cleaning/sterilization? Wouldn't peroxide digest some of the reed
composition?

Appl. No.: 08/179,572
Filed: January 7, 1994
The use of 3% hydrogen peroxide, by itself, provides the most effective
cleansing of the reeds but when used alone causes the reeds to dry out
and warp upon repeated use. The addition of at least 5% glycerol to a
composition containing hydrogen peroxide as in the invention prevents
the adverse action of hydrogen peroxide. Glycerol concentrations,
however, above 10% cause reeds to "deaden" from over-hydration after
repeated treatment. Glycerol concentrations in the range of 7-8% provide
the most effective treatment without the disadvantages of overhydration.
Reeds which have been treated with the composition containing the
preferred concentrations of glycerol and hydrogen peroxide on a weekly
basis retain a clean appearance and do not show growth of molds or
bacteria, even up to at least two years after last use. With proper
storage, such as in a reed holder, reeds treated with the composition of
the invention do not warp as is often the case with untreated reeds. In
addition, treated reeds retain enough moisture for at least one week
after treatment to prevent the warping that generally accompanies
dryness in untreated reeds. Such treated reeds are easily playable by
simply rehydrating the reed with saliva. Regular treatment with the
preferred composition allows reeds to be used between twice and three
times as often as untreated reeds. Thus, if an untreated reed were
acceptable for five performance or practice sessions, a reed treated
according to the invention would be acceptable for use for
10-15performance or practice sessions.
