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?
Based on the torah's instruction וכבסו את אשר בו הנגע, is sourced in mishna, tosefta and the talmud as being a dutiful process of seven key ingredients; (zvachim 95a, tosefta nidah 8 9);
רוק טפל fasting spitlle (active ingredient is (bacilliary) amylase)
מי גריסין chewed pea paste
מי רגלים urine (active ingredient is ammonia)
נתר lye (active ingredient is potassium hydroxide)
