RIT Dye is a common brand of fabric dye. With this product you can dye clothing, wood, carpet, even paper products. Depending on how big the fabric is or how much you have, you can dye your items in a bucket or in the washing machine. Immediately after you're finished, however, you must clean the bucket or washing machine thoroughly to avoid permanently staining it. Disposing of the dye is easy as long as you clean up the dye quickly.
Fill the bucket halfway with hot water.
Pour in the detergent, and swish the water around inside.
Add the bleach into the bucket.
Scrub the entire bucket with a sponge or toothbrush. Scrub the bucket for at least 5 minutes.
Dump the water out. Repeat steps 1 to 5 if necessary.
Turn the water level on the washing machine to the highest level.
Turn the temperature of the water to the hottest temperature.
Pour the laundry detergent and bleach into the machine.
Allow the machine to run the complete cycle.
Repeat steps 1 to 4 once more if necessary. The machine may become slightly tinted from the dye, but that will not affect the clothes to be washed.
