This micro fiber polishing cloth is developed by La Sonanta. We selected an ultra fine fiber material making no scratches at all. It instantly traps and holds dirt and contaminants that dull instrument finishes causing them to age prematurely. Works great with all types of finishes.
Do not use any cleaning solution containing alcohol since this would dissolve the shellac finish and damage the nice French polish finish of your guitar severely. If you clean you guitar strings regularly, never use the same cleaning cloth to clean your guitar, since the little metal particles, left behind in the cloth by cleaning the guitar strings, can cause scratches on your guitar. Shellac finish is very delicate, easily damaged by even skin perspiration, alcohol, heat, fingernails, shirt button or belts. When playing the guitar, always wear long sleeves preventing skin perspiration and excessive body heat. Do not wear shirts with buttons and remove metallic pens in your shirt pocket since preventing scratches to the back of your flamenco guitar.
