Jeans are a staple in many wardrobes. The strong material of the denim ensures that jeans last. They come in many colours, including white. You can easily dye white denim -- and dye it just about any colour you want. Transform your white jeans into coloured jeans (including dark blue) using just a packet of dye and a washing machine. Colour dying white denim is easy, fun and doesn't cost a lot of money.
Turn the washing machine on at the hottest water setting, on the longest wash cycle.
Pour one packet of powder dye into a 4.5 litre (1 gallon) bucket. Fill the bucket almost to the top with hot water. Stir the dye in the water until it dissolves; add the dye to the wash.
Soak the jeans separately in the sink in hot water until they are completely saturated. Place the jeans in the washing machine and push them down into the coloured water.
Dye the jeans for 30 minutes.
Remove the jeans from the wash when they are finished. Rinse the jeans under warm water until the water runs clear.
Place the jeans in the dryer until they are dried completely, about 45 minutes.
Fill the washing machine with hot water. Add 200 g (1 cup) of regular washing powder and 237 ml (1 cup) of bleach. Run the washing machine without any clothes -- this will ensure the inside of the machine does not stain.
Ensure that no other fabrics or clothing are around to be dribbled on by the jeans as you dye them. The dye can spatter and stain the other items. You should also wear a smock or old clothing as to not stain your good clothing. You may also want to wear rubber gloves to protect your hands from staining.
