Instruments and bows need regular maintenance to keep in good working condition and to prevent any minor damage from wear and tear, which can cause additional problems. Regular maintenance work includes the following:
To save instrument it needs regular cleaning must rosin dust on the nail to be cleaned with a soft micro fibre cloth after playing. If you cannot do it with a dry piece, it means that shut be cleaned by a professional luthier. I do not recommend to use commercial cleaning polish and oils as they leave residues to paint surface and can enter the open cracks or gluing, causing unnecessary additional problems.

Gluing open joints
The glue used in the musical instruments, is reversible so that it can be unstuck, in order to be repaired. Joint (where the front and back plates glued to sides) are sometime tend to opening. This can lead to a change of sound, responsiveness, or even buzzers. Importantly, they to be glued, while they are still clean and free of tension.
Regular playing causes small dents on the fingerboard, made of the pressure of the fingers to the string. Over time, the surface can become very uneven, which can lead to the fact that the strings to rattle on the fingerboard and that make difficult to play a double tones. The convenience of playing the fingerboard can be restored by adjusting the arc by violin maker.
The pegs are dependent on changes in humidity and general wear. Overall, if lubricate more regular them with suitable lubricant (peg paste) his live will last much longer when you use rarely lubricated pegs. An old recipe for pegs lubricant recommends a mixture of very old dry soap and chalk. Due to the inconvenience of storing these two components and the difficulty to achieve optimal ratio for good working pegs, it is recommend using of proven brand pegs paste. If key does not behave well and proper folding of the string or the addition of paste cannot correct this is not enough it’s time to makes more serious repair by a professional luthier.
Worn or cracked varnish
Wear from contact with hands or tapping on the bow can remove the varnish and even to reach the wood. It should be restored as soon as possible to prevent contamination and moisture from entering the wood itself. Musicians who play without shoulder rest can wear backboard (in the area of contact with the shoulder) very quickly, as in this case should be regularly restores varnish in this area.
Whether your instrument is only little wear varnish or have severe damage to the body, it is essential repairs are done in a way that respects the integrity of the instrument. Where possible, repairs should be reversible and the original wood and varnish to be maintained.
Depending on the position, length and condition, the cracks may have a small problem that can be serviced within minutes, to a serious disaster could lead to weeks work. Overall, the cracks are easier to repair when fresh, and open wood isn’t contaminated or injured. When cracks are badly glued in the past, or are glued with synthetic glue – will be spent a lot of time to fix the old repair before the crack can be reapplied correctly. If the instrument is opened or the position of cracks allow it, they must to be reinforced on the inside with cleats, a piece of parchment or cloth.
Cracks in the area of the soundpost
This may happen mainly on the front board of the instrument. The downward pressure from the bridge and the pressure upstream from the soundpost makes this area very vulnerable to damage. To do this kind of cracks, just gluing will not be enough, and requires stepping inside with a matched in this area graft made of wood, which reinforces the cracked area.
Cracks in the area of bassbar
As in the soundpost, same pressure of the zone of bridge toward the bassbar cause a pressure that may lead to a longitudinal cracking. Most often in such cracking involves removing bassbar, bonding and strengthening of crack and replace the bassbar.
That are a small list of possible repairs.Remember!!! All repairs is advisable to make by professional luthier. When occur a problem, delaying repair may only to worsen the situation.
