I use Niagara for clothes; but Best Press for quilting.
Here is a description of the product:
Make ironing as pleasant as possible! No more mixing starch with water or environmentally-unfriendly aerosol cans that get clogged. 'Best Press The Clear Starch Alternative' is a clear and fragrant miracle starch that doesn't clog, flake, or leave a residue - even on dark fabrics. Also relaxes stubborn wrinkles, makes ironing easier, and makes fabrics soil-resistant. The clear, non-aerosol spray bottle lets you see how much is left.
