The wash wash scam is a scheme commonly used by scammers who fleece victims by promising them large sums of money in exchange for literally cleaning dirty money. Victims are given fake banknotes that are passed off as being real by dyed. The fraudster promises their victims a big cut if they pay a certain fee and purchase a special cleanser. Scammers commonly seek out financially vulnerable individuals and the scheme is also called the black money or black dollar scam.
