Have had fun reading all the replies to the "coke" question on jean material. Coke used to clean battery post (good) clean chrome on cars (good). Yes, it all works well. Using to soften jeans, yes I remember this...however never did try it as VINEGAR will do the same. Recommend you turn jeans inside out. Coke is very good when U have the flu "just remember it has to be room temperture" used this for years on children. Now they have moved away from home and still get a call for me to go purchse them a bottle of "warm coke".
