Practical, this set of two inseparable vials allows you to keep an excellent sliding slide of your trombone. Usage tips :
• Place a generous drop of liquid from the smaller bottle on each wall of the tuning pump. Spread the liquid by moving the slide up and down.
• Place a little liquid from the larger bottle on the top of the tuning pump so that it spreads over a 10 cm area on the slide.
• Now spray some water on the pump with the SLIDE-O-MIX® Water Spray
. Repeat if necessary.
