How to Change Deep Fryer Grease

When cooking foods in a deep fryer it is imperative that you filter and change the oil regularly to keep the fryer operational and your oil uncontaminated. With heavily used fryers you must filter the oil daily to prolong the life of the oil. However, even with regular filtering the oil must eventually be changed. Draining, cleaning and adding new oil to your deep fryer may seem daunting, but it is really a simple and straightforward process.
