HOLD ON,
Crysla's suggestion may work but ethelyene glycol is NOT something we want in our water supply, it is toxic to most living things. Adding some to a load of wash may make jeans soft, but it could also have the potential to cause serious harm to your local wastewater treatment plant, not to mention everything it could kill if it made it into an aquifer. Let me repeat, ethelyene glycol (anti-freeze) is toxic if ingested and has no place in our water supply system! You wanna take care of all the neighborhood pets and wildlife, leave a bowl of antifreeze sitting outsdie and the local pets will start dropping left and right (Ethelyene glycol is very sweet and has a very pleasant flavor).
