Magnesol doubles the life of your fry oil and saves 50% of cooking oil costs. Magnesol also ensures crisp, golden, delicious fried foods when you filter your oil regularly. Simply sprinkle Magnesol onto filter paper or a filter screen used in conjunction with a filter machine. Magnesol easily removes both solid and dissolved impurities from used oil, extending fry oil life and keeping cooking oil fresh. Magnesol is activated! It is different from any other purifier on the market. Magnesol particles act like a magnet. During filtration they attract and remove food debris and soluble liquid impurities from fry oil. These impurities cause off-flavors and odors which can spoil fried food. They also contribute to oil breakdown.
