I buy sta-flo at WalMart and then mix it with Vodka.............known as the "Quilter's Moonshine". I dip my fabrics in the sink and then roll them thru my newly acquired wringer system.........old top of a wringer washer machine. Saves my hands from wringing them out and saves on wrinkles too. Then I hang them up over my double sink to dry.
Here's a pic of my wringer system............not pretty at the moment but its functional. I'll take it apart another day and paint the bottom half one color. The rollers do not leave a mark on the fabrics either. Tried it out on white muslin and it came out just as clean as before.
