First i would cast a circle. Then maybe wear a protective charm. After that i would remember to make sure it was known that by my will only those of good and kind nature were allowed in. Respect the spirit. After you are done talking, dismiss them. Then maybe smudge the house you live in afterward cause some times they like to hang around after.
^^ creating a board would be best, you can charge it with energy and make it to reflect your beliefs, like carving faeries in it if you follow faerie magic.
the obvious casting the circle, if you can, get some sage smudge so after using it, you can cleanse the space just in case a spirit decides to hang around. when using the board, make sure your fingers are not on the planchette [pointer thingie] they have to be lightly touching it, or resting slightly above it. when the spirit begins to move it, you should feel your fingers being sucked to it, like holding two magnets slightly apart. as well, if the spirit is channeling through you, it's common to hear/feel the response before the planchette moves.
above all though, don't upset the spirit. be respectful and nice, do not yell at it, argue with it, or curse it out. bad things can happen. exceptions though can be made if you know the spirit, but first meetings, be nice, you don't want a vengeful spirit.
I don't have anything to smudge it so what should I do?can I use candle magick for protection or chant for protection?how do I dispose the paper made oujia board?
well, i wouldn't use a paper Ouija board, try to get one or make one from wood.
you can do a cleaning, burn a white candle, and incense like frankincense would work. you'll have to watch the floor with a type of sea salt brew. sage smudge would be best though, but if you are still in the broom closet, then wash the floors with the brew [if you have carpets sprinkle them with baking soda and sea salt] while washing the floor, say a chant and visualize while light with each sweep, covering the house. visualize a circle of light around your house keeping negative energy out.
there's a lot more you can do to cleanse, but that's the easiest way. try to do it once a month since negative energy can build up.
