I tried a regular spray starch and found it left a residue on my fabrics; I didn't like it. Switched to Mary Ellen's Best Press and have had no problems. I just shake the bottle; spray and press immediately. It works great. Interesting to see some people wait 5 minutes or more. For me, I get the right results just doing the pressing as soon as I spray. I love using it and think it is worth the little extra it cost.
