I remember yrs. back when my mom used a product (if I remember called Argo) It was in a box & she mixed it with water & put it on the stove. When mixed she put the lace curtains in squeezed out the put on a stretcher to dry. Wonder if they still sell it? I just use the starch in the cans Spray & iron with another cloth on top until dry. But now going to try some of that vodka mix. Thanks for all the info.
