Dylon Pre Dye, use Before Fabric Dye to Lighten Clothes, 200g

The box says it “may not use well “on bright blue or green but I’d bought it and the dye to cover up some spots on a T-shirt so I thought I’d try taking the colour out and re-dying. Spots faded slightly but no difference to the blue T-shirt - it still looks spotty! Very disappointing. Total waste of time and hours of washing machine use!

Was a bit concerned based on other reviews but this worked incredibly well. I had a black cardigan I’m hoping to lighten to dye another brighter colour and after one use it’s taken it to a faded purple (see pic) so going to use another box. The cardigan is 100% cotton which I think I recommended. Highly recommend but do check it works for your fabric content first as I think that’s why it may not have worked for others

Tried this on a cotton dress. Followed the instructions but it had no effect. Rit is a much better product

Does not work even on a fabric previously dyed with a Dylon dye product!! Used as instructed on packet on a shirt that fits the description of material that should work ( according to manufacturer) this shirt was previously dyed with Dylon Dye. Shirt came out exactly the same colour. Utter waste of money. Smells awful too when in the washing machine. Avoid!!

Easy to use, fairly clear instructions, I think the instructions on the dye pods are clearer so did some of the steps from that, e.g. pre wash without conditioner and then leave wet when adding the dye. I've knocked a star off because I can't fully comment on the predye, I was experimenting with a polycotton blend fabric and so wouldn't know how it fairs on 100% cotton as it is intended. I would buy this again if working with a higher cotton blend or 100% cotton, but the 55% cotton didn't seem to take it.

I used this to pre-wash a jumper I had spilled bleach on. It seemed to work well as the dye took really well and my navy jumper is now very black. One word of warning, it is not a quick process, requiring the longest wash on your washing machine, followed by washing the item, and cleaning the machine. I think it probably took in excess of 12 hours in the washing machine to complete the dye process.

Left some faded marks on a pair of caramel trousers but essentially made no difference to the overall colour. Ive sent for another packet to see if I can get a better result before dying them grey otherwise I guess they will be ruined. Not pleased!!

I used the pre-dye to lighten a pair of dark cream "polyester/viscose" curtains and they turned out fantastic and are now a light cream colour would definitely recommend. I had read that the pre-dye could not be used on certain synthetic materials so bear this in mind.

I wanted to reduce a colour then redye using a different shade

Gebruikt om een katoenen rok te ontkleuren, deze mocht niet boven de 40 graden gewassen worden dus op 40 graden gewassen met de ontkleurder, deze is niet ontkleurd na het gebruik. Zou het niet aanraden!

Not worked for me !
