Discolouration in the gusset of light knickers

Short answer: Discolouration in the gusset of light knickers often comes from the body's natural fluids, sweat and detergent residue collecting in the fabric. Rinse the knickers in cold water soon after wearing, wash them according to the care label and let them air dry.

Why light knickers change colour

Light fabric shows everything the body and the wash leave behind. In the gusset the clothing sits close, and moisture, skin oils and natural secretions work into the fibres. After a few washes the fabric can take on a yellowish or greyish tone, especially if the residue is allowed to dry in.

Rinse quickly in cold water

The best moment to act is right after taking them off. Rinse the area in cold water so the moisture does not set. Hot water can fix proteins in the fabric, so use cold until the worst is gone, and only then wash as normal.

Wash with a gentle product

Use a mild soap without strong additives and dose according to the pack. Gentle products are easier to rinse out and leave fewer residues in the fabric. If in doubt, follow the care label, and wash light knickers with other light clothes so they do not pick up colour.

Avoid too much detergent and softener

Traces of soap and fabric softener can form a film on the fabric that holds on to dirt and makes it look dull. Use no more than necessary and give the machine room to rinse. It also helps if the fabric does not turn stiff or sticky over time.

Dry without heat

Let the knickers air dry, preferably away from the radiator and direct sun, so the fabric does not dry hard. Heat can set discolouration, so check whether it has gone before using the tumble dryer. Daylight gives the best picture of whether the mark is fully gone or only lighter.

If the discolouration stays

Repeat the rinsing and washing a few times before giving up. Older build-up can sit deep and rarely disappears completely on the first try. Always test any extra products on a hidden spot and follow the care label, so you do not wear the fabric down unnecessarily.

Listen to your body

A change in colour or smell that is new to you, or that comes with itching, pain or discomfort, is not something washing advice can solve. Then it is a good idea to talk to your doctor. Ordinary discolouration of the clothes, on the other hand, is quite normal and mostly down to the wash.

Choose underwear you can keep looking good

Soft, breathable underwear that copes with frequent washing makes it easier to keep fresh. See what is available among the bamboo knickers or in bamboo underwear for women. Soft socks for women fit into the same wash routine and can be washed with the lights.
