I have used Sta-Flo that I mixed; it worked okay. I only used it b/c I had it from making silly putty w/ kids.
My preference is Mary Ellen's. I LOVE the Citrus and the Carribean Beach scents. Rose, lavendar, cherry blossom and unscented are also available. LQS quite often has a 16 oz spray bottle for about $8. I bought one, and since then have gotten the gallon refills. I find them online for about $40 - with shipping, it was close to $50! :oops: Or get two from another place when I am ordering from someplace else that is a little more but offers free shipping w/ $100 purchase.
In addition to regular pressing and the crisp look, it gets out even the fold-lines from fabric that is off the bolt. You only need a light mist, not a soaking spray. So even though it's pricey, it does last quite a while. And I enjoy the scent while ironing - anything I can do to make pressing a less awful task...
