I was recently asked about working with demons, and how to best approach them without showing disrespect. While I definitely agree that treating demons like unruly, evil spirits that need to be threatened into submission is a bad idea, I’ve seen many people approach them from the opposite end of the spectrum, subjecting themselves to the demons, or even to a single demon. This is perhaps worse, as it makes you a slave to the demons you call upon.
What follows is a private message I sent to someone else. I have not edited it beyond a few words, so it may read somewhat strangely at times as I reply to things he said, but I think that this is information that many could find useful.
I also know that everyone has their preferred methods of work. When I suggest the books and methods that I have found helpful, I am not implying that others are bad. If I think that, I will say so explicitly. Rather, I am simply offering methods that I use in my own practice, or wisdom that I have found helpful. Even if you do not employ all the methods you read about, reading texts from a variety of authors may help expand your perspective on these matters, and you may even learn something new that you find useful.

Hey there, so before I begin, I would highly recommend checking out Demons of Magick by Gordon Winterfield. The books contains methods of evocation that I have had great success with, and a simpler petition for results, which I have also had great success with. Beyond the ritual methodology, though, he does an excellent job describing how you should approach working with demons.
I also recently made a post describing a simple ritual to contact Paimon, though I would suggest reading the rest of this message first before that one. If you look in my history I also have some other posts that could be helpful to you, such as how to make offerings. The method I describe can also be used to call upon any of the demons of Goetia, though the part that goes, “and by the power of ___” will be different for each demon. You may find the correct name in the above book, however.
While the demons carry such titles as Duke, Prince, and King, you are Emperor, wielding more power and authority than even the mightiest of kings. You command the demons, and they gladly obey their master. This does not mean that you disrespect the demons, for they are glorious, majestic beings of immense power and dignity. However, do not forget that they serve you, not the other way around.
The Divine Names are used to remind yourself that you speak with Divine authority. They are your Names, and by establishing yourself as a generous and mighty ruler, you will command great respect and cooperation from the demons. Treat them as the fiercely loyal, honorable members of your council, and they will work for you with their full power and wisdom.
As for banishings, they are done prior to the ritual to clear the space of any psychic distractions, as well as to brighten yourself in the astral. When you banish, you become more visible to the spirits that you call upon, enabling a greater connection. There is no need to banish again after the ritual, as that is akin to inviting guests over for dinner, and then forcing them to leave right after they are finished eating. You have every right to do so, but it’s a bit rude.
Now, on to the angels. The idea that angels and demons are enemies is one created by mainstream religious culture, and is not indicative of the actual reality of things. The archangel Metatron guided me to call upon Lucifer, and demons have advised me to call upon angels. They are all subjects of your empire, and while their personalities can differ rather drastically, they are all on your side, and will cooperate with each other. In fact, one of Lucifer’s powers is that he may travel between the Heavens and the Hells, carrying messages between the angels and the demons, to allow for communication between these beings, and thus for greater harmony in your reality.
If you read the above book, you will also find that the methods used call upon each demon’s associated Shem angel, as well as three angelic emissaries. This is not to reign in unruly demons, but to empower their work, providing them with wisdom and additional angelic power and oversight. The angels may also constrain the demon, if what you ask for is not in-line with your True Will. I have asked the demons myself if they do not like this, but they actually really like that the angels are involved as it gives them extra power, meaning that you are more likely to call upon them again in the future.
As for Lucifer, I recommend checking out either Rites of Lucifer by the Temple of Ascending Flame or Awakening Lucifer by Asenath Mason and Bill Duvendack (I use the latter, as it is more comprehensive).
In general I would advise reading the posts at galleryofmagick.com, as their blog contains several books-worth of information and advice regarding magickal practice, that can be applied to any magickal system, and to living a magickal life. Their books make up the bulk of my magickal practice, though I have been working more with other beings not covered by them as of late. Koetting also has tons of great info in his videos that I have found to be very helpful. I mention the gallery first because they were how I first discovered magick, and their work is why I am still here in this incarnation today.
Let me know if you have any questions, but I would advise against worrying too much. More worrying means less magick, and true understanding will come with experience. You can read a million occult books, but if you never perform a ritual, you are more ignorant than some guy who jerked off to a sigil once and manifested a ham sandwich, to put it crudely.
. But considering the source of your info 
, OP, I find myself suddenly not surprised.
Never gotten into strife for it either. You can command with authority and respect. Not everyone knows how to do that, unfortunately.
