A Demon for doing cleansing and protection please


I’m in a situation where I need to cleanse a love potion made with blood. I’m trying with Hekate Brimo but it doesnt go. I would like please,some suggestions about a spirit that can cleanse that kind of Black Magic and another for protecting that person. I should be a heavy heavy protection because he/she is under constant attacks. Thank you very much the help you can give to me.
