The launder process for a garment nega

The laun­der process for a nega on a wool, linen or leather garment/vessel is per­formed on the sev­enth day of quar­an­tine of the infected gar­ment.

Does the seven ingre­di­ent clean­ing process depend on the gar­ment own­ers will­ing­ness to go through the trou­ble of laun­der­ing the affected gar­ment?  where he want­ing to make the gar­ment hefker (own­er­less), or just out­right burn it, does halacha afford him that right, or must he go through the process the torah spec­i­fies?

The process
