Disposal of used deep fryer oil requires some extra effort, as most local governments have rules prohibiting pouring of grease down drains (including garbage disposals). Inside the drain the oil thickens, causing clogs in pipes and sewers-- so it'd definitely not a smart wise choice. There are, however, other options, that involve a little bit of work-- but in the long run will save you from plumbing problems. These methods of disposal typically involve containment of the oil properly before disposal at a collection site.
Removing Oil from the Deep Fryer
Unplug the deep fryer and wait until oil is fully cooled before handling the fryer or trying to remove the oil. Set up an area at the kitchen sink or, for larger deep fryers, an outdoor area. You will need a container and utensils for removing the oil from the fryer.
- Use coffee cans, large glass jars, plastic juice cartons or any leak-proof container that will easily receive and hold the cooking oil. You can also reuse the the 3- or 5-gallon drum the oil came in.
- Use a container with a lid if you need to transport the oil any amount of distance.
- If the oil is liquefied, but safe to handle, you can pour it directly into a container. However, have a large scoop or cup on hand to remove thicker oil.
- Next, head to a recycling collection site, keeping the container in a warm place so the oil remains in a liquid form. Recycling centers usually have large collection containers to deposit your oil.
Check local ordinances before throwing out used oil along with household garbage.If permitted, transfer the deep fryer oil into a well-sealed container for disposal alongside your household garbage. Avoid odors and messy garbage cans by preparing the cooking oil for immediate disposal, or refrigerate the container until you remove it from your home.
