Although nylon is used for skimpy underwear and tights, nylon itself is a very tough material. Washing white nylon fabric with mild detergents can cause the fabric to discolour and yellow. And because nylon tends to be quite porous, if you place a white or light-coloured nylon fabric in the wash with coloured clothing, it can easily stain. If your nylon fabric has become a victim of colour bleeding or dye transfer, there are two things you can do to get the colour out.
Fill your washing machine with warm water. Adjust the water level depending on your load -- if you're just washing one piece of fabric, set your water level at the lowest possible.
Add a scoop of strong washing powder. If you have hard water, add a water softener as well.
Add the bleach to the water, and then add the vinegar.
Place your white nylon fabric into the washing machine. Allow the machine to run its full cycle before removing. If the stain is not completely gone, repeat the steps once again. If the stain is gone, move to the next step.
Dry regular nylon fabrics in the dryer. If the nylon fabric is delicate, such as underwear or tights, line or air dry the nylon.
Buy a colour remover for coloured clothing at your local fabric shop or supermarket. Colour removers will remove colour bleeding and stains from coloured nylon fabrics.
Fill your washing machine with warm water.
Pour the entire box of powdered colour remover -- typically 60 g (2 oz) -- into your washing machine. Check the instructions on the box of colour remover to see if you'll need to add your washing powder to the water, as well. Every colour remover is different, and some brands require additional detergents to make the colour remover work properly.
Place your nylon garment into the water; wash as normal.
Dry the nylon garment as usual in the tumble dryer unless the garment is delicate.
