How to Use Rit Dye Liquid for Dyeing Fabric

Note: These are general guidelines. Always check your specific dye and fabric labels for any special instructions.

What You’ll Need

• Rit Liquid Dye (shake well before use)

• Hot water

• Salt (for cotton, linen, rayon) or Vinegar (for nylon, silk, wool)

• Dish detergent (optional, for more even dyeing)

• Stainless steel pot (for stovetop method) or top-loading washing machine

• Rubber gloves

• Stirring stick or tongs

• Plastic or stainless container (for soaking or rinsing)

Before You Start

1. Pre-wash your fabric to remove finishes or residues that may interfere with dye absorption.

2. Identify your fabric type to select the correct additive:

   • Cotton, linen, rayon: Use 1 cup salt per gallon of water

   • Nylon, silk, wool: Use 1 cup vinegar per gallon of water

Method 1: Stovetop Dyeing (Best for Even Results)

Step 1: Prepare the Dye Bath

• Fill a large stainless steel pot with enough water to fully cover the fabric. Heat to just below boiling (~140°F / 60°C or higher).

• Add 1 bottle of Rit Dye per 1–2 pounds of fabric.

• Stir in 1 cup of salt or vinegar, depending on fabric type.

• Add 1 teaspoon of dish detergent (optional, helps create an even colour).

• Stir thoroughly to mix all ingredients.

Step 2: Dye the Fabric

• Wet the fabric with hot water before adding it to the dye bath.

• Submerge the fabric and stir continuously for 10 to 30 minutes, depending on desired colour intensity. Longer soaking results in deeper colour.

Step 3: Rinse and Wash

• Rinse fabric in warm water, gradually switching to cooler water until rinse water runs clear.

• Wash the fabric separately in warm water with mild detergent.

• Air dry or machine dry as preferred.

Method 2: Washing Machine Dyeing (Top-Loader Only)

Step 1: Fill the Machine

• Fill the washer with the hottest water safe for your fabric.

• Add 1 bottle of Rit Dye per load (use double for darker colours).

• Add 1 cup salt or vinegar, and dish detergent if desired.

Step 2: Dye the Fabric

• Add the wet fabric and start agitation for 30 to 60 minutes. Longer agitation yields a deeper colour.

• If possible, pause and restart the cycle to maintain hot water and ensure even dyeing.

Step 3: Rinse and Wash

• Run a full wash cycle with mild detergent after dyeing.

• Rinse with warm, then cool water until the rinse water is clear.

• Wash the dyed fabric separately for the first few washes to avoid colour transfer.

Tips for Best Results

• Always wear rubber gloves to protect your hands from stains.

• For darker colours, increase the amount of dye and extend the dyeing time.

• Avoid dyeing synthetic fabrics like polyester unless you are using Rit Dye More, which is specifically formulated for synthetics.
