Regular: Ultra-Pure Regular Tuning Slide Lube is a safe, all-synthetic grease that is used on all slides of brass instruments. Apply fresh each week for best results. For pro horns, we recommend our Light Tuning Slide Lube for the 1st and 3rd slides which must move easier and faster, but this Regular lube is perfect for the main tuning slide and 2nd slide.
Light: Ultra-Pure Light Tuning Slide Lube is a safe, all-synthetic light grease that is used on the 1st and 3rd slides of better instruments so they move easier for quick adjustments to pitch. Just a tiny amount will do.
