Q&A for How to Use Rit Dye

If you are using Rit dye, use 3 parts purple and 1 part black. Mix with water as directed on the back of the box.

You will need 2 bottles. One bottle is used for each three gallons of water. Use two to be safe. Also, measure the weight of the clothing you plan to dye. More clothing may need more dye. Heavier clothing, such as jeans, may need more dye. Plan with these factors in mind.

I would imagine so, just make sure you leave it in the dye for a long time. The only color you're trying to remove is the yellow that is already mixed with red to make orange, and since red is a more dominant color, enough dye and time should turn it all a solid red.

This a big problem, and while you can make it less obvious, it is very difficult to completely disguise, and satisfactory results can only be obtained on an unpatterned garment. First find a dye that is slightly darker than the unbleached part of the garment. Make up a concentrated solution of dye and apply to problem area with an artist's paintbrush. Tumble dry on high setting and check results. Repeat if necessary. Now dye the whole garment as per instructions.

Use vinegar. Salt is good for cottons. Both solutions soften the fabric so the dye can get through the fabric, resulting in a more uniform color.

On the rit dye website, you can access a colour formulas page which allows to choose a more specific colour shade that you want. It will then ask for the item size and will in turn give you the amount of dye needed for that particular shade. There is also no harm in experimenting.
