Outta instinct I almost threw a couple jokes out there, oldred lol. That is til I remembered this stuff that a friend of mine who runs a print shop here gave my wife. It was similar to Fast Orange, which is what I use, but it was definitely smoother with no grit. He gave it to her cuz she told him about some "unremoveable" stain in a nice shirt and shed tried everything on it but he assured her itd get it out. And he was definitely right. So I used it for cleaning my hands (once I found out where shed hidden it) and I can honestly say I never found anything it wouldnt remove. I cant remember the name of it cuz it was many years ago, but Im sure if ya called a couple of print shops theyd tell ya, cuz there aint much thats harder to remove than printers ink
