The bridge of the dulcimer is generally carved with horizontal lines, which can withstand the vertical force, but the tolerance to the horizontal force is weak, so it is necessary to avoid the horizontal force from damaging the bridge. It is common for the dulcimer to be scratched or broken when handling the dulcimer with little care. Therefore, the handling of the dulcimer should be extra careful, especially not to scratch the surface of the dulcimer. When repairing the bridge or the bracket is broken or fallen off, save the broken part for repair. When repairing, use a tuning hand to loosen the strings, apply a little 502 glue to the broken part of the bridge, straighten the position of the fracture and press the bridge firmly, and wipe the excess 502 clean. After the glue is dry, tighten the strings and tune them. If you lose the bridge or the broken part of the bracket, you should ask an instrument repairer or professional woodworker to deal with it.

Dulcimer strings in humid areas are affected by moisture and often touch the strings with hands, which can easily cause rust on the strings. In this case, it is necessary to develop a good habit of maintaining the strings. For example, regularly apply some anti-rust oil or sewing machine oil to the strings for protection, and try to avoid the rust phenomenon caused by rubbing the strings with your hands. When the dulcimer does not have rust on the strings for a long time, it is advisable to use fine sandpaper to remove the rust, and then apply protective oil.
