Suitable for trumpet, euphonium, or tuba, this nickel-plated rod can be used to clean the inside of the valve casings, where any build-up can hinder smooth and fast valve action. After removing the valve, thread the rod with some absorbant fabric (such as cheesecloth) and push it up into the casing to remove residue.
