After precleaning HAs by soaking in ED, 1% SH, used in combination with US, can be preferred for decontaminating HAs due to its superior cleaning efficiency and minimal surface alteration regardless of HA macrogeometry. In cases where placing unused HAs is not feasible, this three-step protocol may present an efficient and cost-effective alternative for at least one reuse cycle.
