If you’d like the flexibility of a “customized” lubricant for your trombone slide, Slide-o-mix can fill that need. By using different proportions of the two bottles.
“Apply a large drop of liquid from the smaller bottle to each of the stockings of the inner slide. Spread the liquid by moving the outer slide up and down.”
“Apply some liquid from the larger bottle to the top of the inner slide, so that it trickles about 10cm down the slide tubes. Then spread this by moving the outer slide. Now spray a little water onto the inner slide.”
