A black long-sleeved top without a grey cast after many washes
Short answer: A black long-sleeved top can get a grey cast after many washes, because the colour fades and lint settles. It can be limited by washing cool, turning the garment inside out and using a mild detergent for darks. Here is the routine that keeps the black.
Why black turns grey
Black clothes turn grey when colour particles are rinsed out in the wash and when limescale and lint settle in the fabric. Heat and rough washing speed it up. Some fabrics fade faster than others. So it is about washing gently and only when the garment really needs it.
Wash cool
Follow the care label for your black long-sleeved top and choose a low temperature. Bamboo clothing is viscose made from bamboo, and viscose reacts to heat and rough handling. Cool water keeps the colour better and is gentler on the fabric. See women's long-sleeved bamboo T-shirt.
Turn it inside out
Turn the black long-sleeved top inside out before washing. Then the outer fabric wears less, and the colour on the visible side lasts longer. It also helps against lint and rubbing from other clothes in the machine. Turn it back when dry and shake it out lightly.
Black long-sleeved tops and detergent
Use a detergent for darks that is made to protect colours. Avoid bleach and strong stain removers that can lighten or discolour the fabric. Do not use more than the recommended amount, because detergent residue can settle and give a grey cast.
Wash blacks together
Wash black with black and other dark clothes. That way you avoid light lint settling and colours running. Do not wash it with towels and other linting clothes. A laundry bag can give extra protection against rubbing, especially over many washes.
Hard water and limescale
If you live in an area with hard water, limescale can settle in the fabric and give a grey cast. A detergent against limescale or a water softener can help. Some people also rinse an extra time. It is a good idea to follow the detergent's dosing instructions for hard water.
Drying without heat
The tumble dryer can make black fade and wear the fabric. Let it air dry on a rack away from direct sunlight, which can also bleach it. Hang it on a hanger or lay it flat. That keeps colour and shape so it looks good for longer.
Wash less often and air it
The less often you wash, the longer the colour lasts. Hang it up to air if you have only worn it briefly and it is not dirty. Keep several pieces in circulation so they are not washed every time. Combine it with bamboo tops for women and a bamboo slip.
Frequently asked questions
Why does my black long-sleeved top turn grey
Because the colour fades in the wash and lint and limescale settle in the fabric. Heat and rough washing speed it up. Wash cool, turn the garment inside out and use detergent for darks.
Can I wash black clothes with other clothes
Preferably with other black and dark clothes, so that light lint and colours do not run. Avoid washing it with towels and other linting clothes.
Can a black long-sleeved top go in the tumble dryer
It depends on the care label. Many recommend air drying, because heat can make black fade. Hang it on a rack out of direct sunlight if you want to keep the colour.
