I got 2 very old christening gowns & several old baby dresses that were in awful condition. They were stained & yellow. I went online & got these tips. If possible put a towel under whatever you are washing. This way, when you lift the item out of the water, the weight of the water is on the towel and not on the delicate fabric. I desolved OxyClean in very hot water and let the water cool down. I soaked the items for at least 24 hrs. but some things required longer soaking. When the items were clean I rinsed them well again using a towel under them. For white things I put them on a clean bath towel and put them in the sun for a couple of days. Be sure to turn them over so they are evenly sunned. These clothes came out beautifully with no damage to the fabric. I ironed them and have them stored in acid free paper. Good luck and I hope these tips work for you.
