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

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!

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!

Not worked for me !

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
