The guitar is one of the most widely played instruments in the world. Some play them for fun, others play them for performance, and others play them to earn money. This is why a guitar players must be able to take care of their guitar to the best of their abilities.
There are many things to consider in maintaining a guitar to last in its optimal condition for a very long time. The guitar must be clean from dust, stains or other dirty materials like insects waste. The guitar neck must always be regularly checked out to avoid possible issues like warping. Guitar strings must also be replaced when rust starts to build up.
Rust build-up is really an issue for a guitar. It affects the guitar’s aesthetics as it gives a dirty brownish color and takes off the coating of its metal parts. Rusty guitar strings are also more likely to sound bad and can give an inconsistent tone or even snap in the middle of a song and potentially even cut your fingers.
Guitar screws are also very susceptible to rust. Depending on the design of an electric guitar, some guitar screws are found in the bridge, saddle, pickups, output jack, strap button, pickguard, tuners, tuning pegs, neckplate, backplate and many others. Having a rusty screw in any parts mentioned can significantly affect the condition of your guitar.
A guitar screw eaten by the rust in the strap button can make it difficult for you to put the guitar on your neck as it has a high chance of falling off. Rusted screws in tuning pegs can also affect the stability of your guitar strings which could make it very hard to tune. Damaged screws from rust in pickups can also cause problems as pickups can fall as is cannot hold on their own without the screws.
So, where do rust really come from? The rusting occurs when the iron is exposed to the combination of oxygen and moisture over a period of time. This results in the iron going through a process called oxidation which produces iron oxide or the brown substance we call rust.
There are many reasons why rust exists in your guitar. One is your storage conditions. Rust can build up quickly in your guitar when you store it in a place with high humidity. Playing with wet or greasy hands can also cause rust in some of the guitar parts, as moisture can quickly build up when it is wet.
But one of the main reasons why rust is building up in your guitar is that it uses cheap materials that are more susceptible to corrosion. When the components of your guitar, including the screws, are made from ordinary metal, then there is a high possibility that rusting can occur.
