i do not use plant based oils other than olive oil for cooking. things like crisco, canola, and other veggie oils are safely usable once. they also have an excessively low flashpoint and ruin good frying pans.
i use animal lard as it is stable at room temp does not go rancid if used over and over for several cooks.
but to strain bits out heat the oil past 100degrees before straining. i use a strainer like this
put a paper towel in it and hang it over clean bowel or pan. pour in oil.
there are pricer dedicated devices but paper towels are cheap and they work
