Can faultless starch be used as baby powder and where do you purchase this item?

When my daughter was born, over 33 years ago, a registered nurse friend told me to get the powdered faultless starch for her diaper rash. We had already gone through A&D ointment and a prescription ointment that didn't work. I put the powdered starch in a shaker and sprinkled it on at every diaper change until the rash got better, usually in a day or two. The only problem is that I can't find it anywhere! Thank goodness I still have some leftover from 29 years ago when my son was born! I am now using it on his 1 yr. old son. It has also been helpful, over the years, to clear up scalding, chafing, heat rash, etc. This box is 29 years old and still works better than anything else on the market!! If you find some, BUY IT! Evidently it doesn't get stale or become ineffective.
