Boss ItWash & Dye Black, Intense Black Dye for Clothes - Just Pop in The Drum, Easy to Use Fabric Colour for Washing Machine

Really easy to use, excellent result, and didn't discolour the washing machine. Very pleased, gave old jeans a new lease on life. Cannot yet comment on washability as not yet laundered since dyeing process.

The zipper broke on my favourite black jeans I was looking for a new pair and thought why not dye some of my old faded pairs to see if I could save some cash. My faded black jeans are now black! Very easy to use, just cut the top of the pack off, pop in the washer with whatever you want to dye and wash as per the instructions. I popped 3 pairs of faded black jeans into the drum and 1 hour later I had jeans that looked brand new! I saw some of the negative reviews, my washer is absolutely fine! My washer is only 2 years old. After using blind wash with a egg cup full of bleach to remove any residue. Saved myself at £90.00 (3 pairs at £30 a pair). Great product! Highly recommend.

Great depth of colour BUT….ruined the washing machine!!!Thick black dye residue in seal of washing machine door. Needed to run on empty cycle 4 times & then it still stained other clothes.

I had some reservations due to some of the negative feedback, but it worked well (I used a whole sachet for a pair of shorts) and I didn't find the dye bleeding into the next washes like some reviews, however I did let the washer dry for a couple of days, and it did stain inside the rubber seem. But we aren't precious over the washer and there was a little mould previously so we didn't mind. But I didn't the machine after dyeing other than the normal wash, so the staining MAY be avoidable if rinsed properly

Fabulous product. Definitely works best when you only use the recommended amount of fabric and no more. Also be mindful that any yellow tinge to the fabric will result in a greenish tinge to the final colour but on pure white fabric it works brilliantly and the result is black as coal. Have yet to wash the fabric so have no idea how it will turn out.

Ha a pair of cargo trousers that went from black to grey. Figured will try to use a dye to renew the color as the trousers themselves were fine. This product is easy to use. Just follow the instructions. Put it in the washing machine and wash a few times. That's all it takes. And the item comes out looking as new. Would buy it again and definitely do recommend

It did dye... but it's navy, not black! All instructions and advice been followed.

I’ve bought this twice and used it to dye some of my black clothes, I was really impressed with the result. I’ll definitely be buying it again when next I need to dye.
