Add a note to encourage purchase
Rotary Valve Lubricants, model 11 -- Light Rotor: Child Resistant Cap.
A synthetic lubricant formulated specifically for musical instruments with close-tolerance rotors. Long-lasting formula provides for a quick action while guarding against corrosion and wear.
Siegfried's Call recommend purchasing the H11 with the child resistant cap. Use sparingly down the center of the outer tuning slides of the valve block. We suggest one or two drops once a week.
