Super for black / dark wash

I now wash for months my dark wash (jeans, black T-Shirts etc.) only with the "Coral Black Velvet". It is tstsächlich so that the colors remain with this detergent longer dark and less fading, which can be determined mainly very good at jeans.
In addition, it washes very clean and the smell is very pleasant.
I will certainly stay true this good detergent for a long time.
