Your violin does not need to be spotless but it does need to be cleaned up a bit after playing.
It is important that you not let rosin dust and finger oils build up.
Rosin will bond with the finish and over time become nearly impossible to remove. After playing, wipe the rosin dust off the violin. Wipe the strings off, and wipe the fingerboard now and then.
Use a soft dry cloth. Dampen the cloth if needed but limit the use of moisture on the violin unless it is necessary.
Occasionally use an instrument polish to bring back the shine or clean difficult areas. Do not use polish everyday. Polish is abrasive and slowly wears away the finish.
Never use furniture polish on your violin.
Always test a polish or soap on a small area to make sure it is safe to use on the instrument.
Cremona Violins are made in China. Cremona was one of the first major brands to be imported to the USA from Asia. They have become a favorite among teachers and students, due to their value.
