Tips on pedicures?

For context I (28M) usually paint my wife’s (29F) nails and after thinking about it I got one of those little foot spa things from the store and have used epsom salts and essential oils to sort of give her the whole experience at home. She loves it, but I’m by no means positive with what I’m doing. Any input would be appreciated. I’ve figured out how to use the pumice stone and the other sorts of tools that help to keep her feet soft, but aside from all that I’m still sorta clueless.
