How to Free Up a Rusty Trombone Slide

Introduction

A rusty trombone slide can hinder the smooth movement and performance of your instrument. However, with the right techniques and care, you can free up a rusty trombone slide and restore its functionality. This article will guide you through the process of cleaning and polishing the slide, as well as provide insights into professional reconditioning options. The information presented here is based on expert advice and reliable sources in the field of trombone maintenance.

Cleaning the Slide

The first step in freeing up a rusty trombone slide is to clean it thoroughly. Follow these steps:

  • Use a trombone snake specifically designed for trombone slides. This tool helps remove any oxidation build-up inside the slide tubes. Insert the snake into the slide tubes and move it back and forth to dislodge any debris or corrosion.
  • Instead of water, you can use vinegar as a cleanser for the inside of the slide tube. Vinegar helps remove oxidation effectively. Apply a small amount of vinegar to a cloth or brush and gently scrub the inner surface of the slide tubes.
  • If there is visible oxidation on the chrome-plated slide that doesn’t come off with rubbing, it may be necessary to have the slide tubes re-chromed. Consult a professional repair shop for this service.
  • For smooth movement, lubricate the trombone slide with a thicker lubricant. A mixture of Vaseline and valve oil works well. Apply a small amount of the mixture to the inner slide tubes and distribute it evenly by moving the slide back and forth.

Polishing the Slide

If the outer slide tube of your trombone is severely pitted, you can try polishing the bore to improve its condition. Follow these steps:

  • Obtain brass polish, rags, and Scotch-Brite pads from a hardware store. These materials will aid in the polishing process.
  • Create “bore swabs” by tying a string around pieces of cloth. Apply brass polish to the swabs.
  • Insert a swab into the slide and pull it through the tube, going back and forth. The swab will help remove any remaining corrosion and improve the smoothness of the slide.
  • Rinse the slide thoroughly with water to remove any residue from the polishing process.
  • Apply a liberal amount of slide grease to a clean swab and pull it through the slide to ensure a protective layer of grease on the inner tube surface.
  • Don’t forget to clean the water key to remove any accumulated debris. Use a cloth or brush to clean the key thoroughly.

Professional Reconditioning

In some cases, if the slide cannot be effectively smoothed out or if you’re concerned about wearing it out, it may be necessary to seek professional reconditioning. However, it’s important to note that professional reconditioning can be costly and may exceed the value of the instrument. Consider consulting a reputable repair shop to assess the condition of your trombone slide and discuss the available options.

Conclusion

Freeing up a rusty trombone slide requires patience, care, and proper techniques. By following the steps outlined in this article, you can effectively clean and polish the slide to restore its smooth movement. Remember to take precautions when using cleaning agents and consult professionals when necessary. With regular maintenance and care, your trombone slide will provide optimal performance and enjoyment for years to come.
