I cleaned 2 aparments last week with the same stains, the owners were indians. i did some research about it, the indian women get a tattoo with henna dye for cosmetics purposes and those stains are from henna tattoo. Are those stains are permanent? if is possible to remove them, how and what chemicals? How often you guys face that situation? Thanks guys.
I 'm not sure exactly if Henna is a plant? if so something like Stain Magic or Stain Zone from Bridgepoint should do the job. It may take some time and more than one application UV light or heat may help if it is real stubborn. Bobby
This answer is right on the money. Henna is indeed plant material. An oxidizer works best. Scott Warrington
I tried stain magic and it didn't work, what it really help a lot with not 100% success was a rust remover. But now I think that protein enzyme spotter might help.
