The first step to using the dye is preparing the area by covering it with a plastic table cover or newspaper. Have paper towels and sponges handy. Wear rubber gloves to protect the hands and use plastic buckets or stainless steel pots fort the dye bath.

Remove stains from fabric or use Rit Color Remover to get fabric to an off-white or cream color to help achieve uniform results when dyeing.

In 2 cups of very hot water, dissolve the dye thoroughly to avoid dye spotting. Stir the dissolved powder or liquid dye into the bath until evenly dispersed. Use a water temperature of 140 degrees Fahrenheit for deepest color. If dyeing more than one color, starting with the lightest color usually works best.

Adding 1 cup of salt to the dye bath when dying fabrics containing cotton, rayon, ramie or linen creates more intense color. For nylon, silk and wool, add 1 cup of white vinegar to achieve that effect. Wait to add the salt or vinegar until five minutes after the fabric has been added to the dye bath if possible to help promote level dyeing. To help promote the level of dyeing on all dye baths, add 1 tablespoon of laundry detergent to all dye baths.

Longer immersion in the dye bath results in deeper colors on the fabric. Items can remain in the bath for up to one hour, as long as the water remains hot. Be sure to constantly agitate or stir the item in the dye.

After removing clothes from the dye bath, use warm, then cool water to rinse them until the water runs clear. Finally, wash the fabric in warm water with mild detergent, and then rinse thoroughly in cool water. Machine dry or hang dry.
