Color uptake amazing on cottons.
Didnt touch my green polyester mix nurses tops. Wanted to dye the off white trim green as gone slightly dirty white.
Disaster as just went a hint of dirty green.
Possibly there wasn't enough cotton in the mix?
Instructions did say it wouldn't dye polyester but mixed fabric would come out a lighter shade.
Bath matt was dirty white.
Washing the items again after and then putting on empty wash to clean machine more work than I thought.
If it had dyed my nursing tunics it would have been good value for money as wouldn't need to buy 3 more!
