A black t-shirt that stays black after many washes
Short answer: A black t-shirt keeps its colour longest if you wash it inside out, at a low temperature and with a detergent for dark clothes. Avoid the dryer and strong sun, because heat and light are what turn black into grey.
Why a black t-shirt fades
The black colour sits in the fibres, and every wash pushes a little of it out, especially when the water is warm and the clothes rub against each other. A black t-shirt can therefore get a greyish surface even though it is intact. Here are the habits that make the most difference.
Wash inside out and at a low temperature
Turn the t-shirt so the outside does not rub against the drum and other clothes. Choose a gentle programme and a low temperature, because warm water opens the fibres and lets colour seep out. See also bamboo T-shirts for men if you want more dark basic t-shirts.
Use a detergent for dark clothes
A detergent for dark clothes lacks the brighteners that ordinary detergent often contains and that can make black look greyer. Dose by the pack and do not wash with light items. If you are unsure, read the label and try one wash to see the difference.
Wash black clothes together, but not packed full
Sort by colour and do not fill the machine. Black clothes rub against each other more when the drum is too full, and that speeds up bobbling and wear. Wash the black t-shirts with similar dark items and avoid heavy pieces such as jeans and towels.
Dry without heat and without direct sun
The dryer and strong sun are enemies of black clothes. Hang the t-shirt to dry inside out, in the shade or indoors. Some t-shirts can take a short spell in the dryer, but read the instruction and take it out while it is still slightly damp.
Avoid softener and strong stain removers
Softener can leave a film that makes black look dull, and strong stain removers can take colour with them. Use gentle products and test on a hidden spot. If you save on chemicals, the clothes often last longer.
Watch out for bobbles
Bobbles make a black t-shirt look grey and worn. Wash inside out and avoid contact with zips and hook-and-loop tape. Remove bobbles with a fabric shaver or a blade, and take care not to damage the fabric. Add bamboo underpants for men to the same wash if you like.
Know the limits of your t-shirt
Even with the best care, black clothes gradually get lighter, and some fabrics fade faster than others. Read the label, follow the care instruction and do not expect it to look new after a hundred washes. It can, however, stay nice for longer. See also all bamboo socks for men.
Frequently asked questions
How hot can a black t-shirt be washed?
It says on the label, but a low temperature is usually best for the colour. Wash inside out on a gentle programme with a detergent for dark clothes.
Can I restore a faded black t-shirt?
Partly. There is fabric dye that can refresh the colour, but results vary. Prevention is easier than repair.
Can black clothes go in the dryer?
It is best to avoid it, because heat fades the colour. If the label allows it, use low heat and take the t-shirt out while it is slightly damp.
