How do you wash with WEN?

Excuse me, could you elaborate on the process of "washing with WEN"? Is it a specific type of cryptocurrency cleaning or sanitization method? Is it a service offered by WEN, a cryptocurrency exchange or platform? If so, how does it work? Does it involve transferring funds, verifying transactions, or is it a security feature? Additionally, are there any fees associated with this process? Lastly, how does it benefit users of WEN or the cryptocurrency community at large? Thank you for your time.
