text: Probably, pump it through an automotive oil filter.  They are designed to filter out particles a micron or greater and handle all sorts of viscosities of motor oil.  My guess is that the viscosity of cooking oil will be much lower than that of motor oil, so an automotive oil filter should work fine.  Walmart has its own brand that are made by Champion Labs (same oil filter as Bosch, STP, etc.) and is about $2 each.
