I keep this filled with vegetable oil or canola oil to coat my cast iron cookware after cleaning. Makes it easy and I don't use excess oil. And I don't have to use spray oil that gets everywhere.
We grill a lot of chicken and used to dip a rag in oil and apply it to the grill to keep the chicken from sticking. We wanted something better, and found this. We have used this a few times and it has done its job. It is very flimsy, and feels cheap, but it does its job. The oil will drip when held upside down; it would have been cooler if you had to squeeze it to get the oil to come out, but whatevs, it still works. I have no complaints and would recommend this to anyone who is wanting to use it.
