Dr. Beckmann Intensive black cloths, for intense black and smooth fibres, 6 cloths

If you need your black clothing to recover to black, its a great product. Value, it is a little bit pricey, but to think about how much money you have to spend on new black tshirt, this would be the choice.

It really enhances the color of the fabric — it’s not a dye, but it improves

This stuff is AMAZING! I have a lot of black clothing, especially scrubs, which get washed, A LOT. You throw one of these sheets in the washer (2 for large loads) and your black clothes look new again. It doesn't stain your washer, definitely worth the money. I will buy again.

Works well, not for all fabrics types, no english instructions , made the cloth darker

I bought these thinking that they would help retain the color of my black clothing. I wear a LOT OF BLACK, but since I don’t speak or read German, I’m at a loss as to how much to use these things. I’ve used them in a couple of loads of dark clothes and they haven’t hurt anything, I’m really not sure if they’ve helped either. My bad for ordering this product. I guess I was hoping for some clue in English to help me navigate this product. I’m going to stick to products with English instructions instead of just trying to wing it on my own. At the end of the wash cycle, the sheet, sans black dye sat in the bottom of the washing machine.

It is what I had been looking for! 1 sheet for navy, 2-3 for black. 1 sheet of 1-2 clothes.

I bought this product because it was supposed to change color — but it doesn’t do anything. I followed the instructions exactly, tried multiple times, and there was absolutely no color change. It just stayed the same dull color the whole time. Totally misleading description. Waste of money and time. Would not recommend.

It works! I didn’t believe it would work and bought it just to try it. I was impressed!
