AlphaSynth Trombone HandSlide Oil

Superslick’s AlphaSynth Trombone Handslide Lube. A little bit goes a long way! Clean the inner slide before application and simply apply a drop or two to each stocking, spread with your fingers across the entire inner slide tube and spritz with distilled water. 

Having a handslide lubricant for your trombone is incredibly important. If you don't Lubricate your slide regularly it will get stuck.
