The cloth doesn't really need the oil added every time, and the scent is up to you. When I do husbands work laundry I don't dose the cloth and it gives a softer smell.
I also change scent on occasion. Vanilla and mint in the summer... A touch of sandalwood int he cool months...
“You have your way. I have my way. As for the right way, the correct way, and the only way, it does not exist.”
And that's why I'm here eating HFLC Primal/Paleo.
