How do you filter used cooking oil?

Answer 1

Not sure if this applies but my mother use to strain her cooking oil (which was beef talow/fat) by heating it up and then strain it through a cheese cloth linen towel. That would take out all of the bits and pieces that were in the oil. She would then place the clean oil into a container and place in the freezer or if you're going to use the cooking oil on a reqular basis (3 to 4 times a week) you can leave it in the deep fryer with a lid on it. She did this a couple of times a month.

Answer 2

Alton Brown recommends this procedure: Put a quadruple layer of cheesecloth into a funnel, and then put a strainer on top of that (the metal screen kind). Keep the oil in a dark glass container (such as a wine bottle) since exposure to light over time can make the oil go rancid.

Answer 3

Boil it wit equal parts water the let it cool. The water will collect the impurity's. Then all you have to do is remove the oil from the top of the water.

Answer 4

I settle mine through a paper coffee filter, it almost totally cleans it.
