Rit DyeMore Synthetic Fiber & Shoe Dye makes it possible to dye synthetic fabric and fabric blends, which includes anything with 35% or more polyester, acrylic, acetate, or nylon. Also works great to dye the rubber soles of sneakers! 

The versatile, easy-to-use and non-toxic liquid RIT royal purple dye is perfect for rejuvenating faded clothing, customizing shoes and much more! 

How to use Rit DyeMore Synthetic Dye:

• Start by boiling about 3 gallons of water in a large stainless-steel pot using your stove or cooktop. Due to the complexity of dyeing synthetics, you’ll need to use your stove to maintain high heat for the duration of the dyeing.
• Add 4 ounces of Rit Dye per pound of fabric. The key is to make sure your dye bath is big enough for the fabric to move freely. If dyeing 100% polyester, double the dye.
• Dye your item(s) for anywhere between 10-30 minutes, depending on how bold of a color you are trying to achieve.
• Wash & Enjoy!
