Cooking oil or grease sticks to pipes when poured down the drain and may cause possible backups and/or sewage spillage. Flushing pipes with hot water will not always clear clogs. For a small amount of cooking oil use the following steps to safely dispose of it.
- Pour (cooled) cooking oil into the can and allow it to solidify then throw it in the trash. If grease is solid, scrape it onto a paper towel or into a can and throw it in the trash.
Check with a local restaurant or pizzeria to see if they allow the use of their drums or bulk tanks to pour a large amount of cooking oil into.
