I posted earlier that I was using vinegar on my sheets and towels. This is the first time I have used vinegar on either. I wasn't very happy with the results of using vinegar on my sheets. I have 100% cotton sheets with a high thread count, and I am fond of the "crisp" feel that they have after being freshly washed and dried. The vinegar made the sheets feel soft, so I won't try that again. But, on the towels and other laundry, success!
