Rit Dye Synthetic 7oz-Racing Red, Other, Multicoloured, 207 ml (Pack of 1)

Used it to dye some bras which were white but had gone in with a darker towel accidentally and had left them a grey that wouldn't budge.Put it in the washing machine with a pump of dish soap and used the whole thing.Ran a wash on the 95 degrees cotton cycle and added an extra rinse at the end.Absolutely no issue at all. So easy. Way easier than standing over a stove for an hour. The red took really well to the lace overlay and the straps, the cups underneath are a much lighter red which looks great!They look so much better!A lot of complaints I'm seeing are folks who are anticipating block colour over multiple fabric types. Different fabrics will hold colour differently. It worked really really well, they look fantastic, like new, it was super easy.Would def buy again.

Followed instructions but colour didn't set

I used this to colour some parts I had 3D printed in nylon. I'd never used fabric dyes before, but this is very simple to use. I just added a dollop of dye to a pan of steaming (but not boiling) water and submerged my parts. As this is already a liquid that's all there is to it. I could get a very deep red (almost maroon) by dyeing for several minutes or a much lighter red (nearer pink) with only 30 seconds. Once it had cooled I decanted the diluted dye into a container to use next time, I expect I'll get a lot of mileage out of this bottle.

Used this colour with the graphite as recommended by RIT to cover a green. Didn't work so a waste of money, time and a garment that is now a darker shade of green instead of black.

Incredible- used it to dye my synthetic hair extensions and it worked really well.

i am sorry that I have not done pictures after and before to my jacket. lovely product. it made it like new. easy to use.

I had a “neon orange” coloured dress that was lightly stained and wanted to darken into “racing red”. Followed the instructions, left the dress in the colour bath for over an hour but there was no change other than the brightness of the original orange faded away and was replaced by a dull earthy orange. Stains still there obviously.I used the same dye on cotton just to get some value out of my useless purchase and the T-shirt from white became red (not quite the racing type!), as expected.So it probably is NOT effective with synthetic fabrics. Fullstop.Image shows both garments AFTER dye application for comparison purposes.

I have used various colors in this line on polyester that are amazing, and sadly this color just doesn't seem to have the same vibrancy as the others.
