- Fiber content and weight affect how color appears. If you are in doubt as to whether your fabric will accept dye or achieve the color you want, we recommend testing a swatch first.
- Before dyeing, remove any visibile stains on the garment. This will help achieve uniform color results when dyeing. Pre-wash item in warm, soapy water. This helps to remove any finishes that may interfere with dye absorption.
- Cover work area with plastic table cover and have paper towels handy to protect against any possible spills.
- Fill a microwave safe container with very hot water, enough to cover your item (4-8 cups).
- If using liquid dye, pour 1/2 cup of well-shaken dye into the container and stir well. If using powder dye, dissolve 1 package of dye in 2 cups of very hot water and stir well. Pour into container and stir well.
- Wet item in warm water and squeeze out excess water.
- Immerse item into dyebath and gently push down with a spoon so it is completely covered by the dye. Cover container with plastic wrap. If dye-painting or wax-less batik dyeing, wrap fabric in plastic wrap, sealing the outer edges.
- Line bottom of the microwave with paper towels to protect against spills. Place container in microwave and set on high for 1-2 minutes. Check after 1 minute to be sure plastic is not melting as the power of microwaves varies. If dyeing nylon, only heat it for 15-30 seconds, and not for longer than 1 minute, as it is very heat sensitive. Watch fabric closely while doing this.
- Carefully remove the container from the microwave. The plastic wrap will be hot so wait a few minutes for it to cool.
- Remove plastic wrap and remove item from the dye bath.
- To enhance the color and reduce color bleeding, use Rit ColorStay Dye Fixative immediately after dyeing and before washing, following these instructions.
- Rinse in cool water until rinse water begins to run clear.
- Wash in warm water with a mild detergent, rinse and dry.
- Clean microwave safe container with soap, water and chlorine bleach.
