How to Wash Blacks Before They Fade
First of all, you should know that black clothes should be washed after being used a few times, especially skirt , shorts , trousers , knitwear , shirt ones. No matter how careful you are, washing machines can wear down the paint, causing signs of fading.
Washing by turning it upside down will protect it slightly from the abrasive effect of the detergent.
Very high temperatures and long washing programs should be avoided. 30 degrees is suitable for black clothes to prevent fading.
Liquid detergents specially produced for black clothes should be used because these detergents are formulated for dark colors.
Tumble dryers should not be preferred because they collect a lot of fluff and are a hot and long process, and they should be hung to dry without exposing them to too much sunlight.
