Use Easy On Speed Starch to make ironing easier and faster to create that sharp professional look. For heavier fabrics like linen, denim, and linen collars and cuffs, try Easy On Double Starch. How to use: Shake thoroughly both before and while using. Match a red dot on the can with a black dot on the push button. Hold the can 6–10 inches away from the material. Spray as depicted, at a 45-degree angle. This enables the dip tube to completely drain its contents. Spray evenly, moving back and forth. Don't soak too long.Use the heat setting specified for the fabric you're ironing (important: use the cotton setting for linen). Right after spraying, iron swiftly and smoothly. Large items should be sprayed and ironed in sections. Iron once more for even crisper results. After use: To prevent clogging, remove the push button and rinse in warm water after each use. Replace, lining up black dot with a red dot. Warnings: Keep out of reach of children. Contents under pressure. Do not puncture or incinerate the container.
