Dr. BeckmannIntensive black cloths, for intense black and smooth fibres, 6 cloths

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.

Why did you pick this product vs others?:Very good product to keep black clothes in better shape, it works better in cotton fabric.

These intensive black cloths are perfect for reviving faded fabrics. Designed with rich, deep black and smooth fibers, they restore color effortlessly, add 2,3 for more intensive black color .Convenient and easy to use—just toss them in the wash for bold, renewed black garments. No mess, no hassle, just results. A must-have for keeping your clothes looking fresh and vibrant!

it works fine but the instructions are written in german which is annoying

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 works!!!!Easy peasy lemon squeezy!No mess, just buy it!

The box is open and wrinkled, two napkins are missing, you won't get any effect from them even if you use them all at once, they won't restore the color of things.

So, I'll keep using this up, but I'm not sure I noticed darkening in the (mostly COTTON) faded black clothing I washed with this. I get that its a dye, and not meant to catch/hold on synthetics (which dont fade as bad anyhow). Perhaps its other benefits (fiber renewal?) will becone noticeable with a few more uses, but already collecting black cotton items to wash separate is feeling annoying. Doubt I buy again.
