Confused where to pour your used oil?
Do NOT put it down the drain.
Suppose you just made some french fries.
You are left with dirty hot oil so what next?
Just add some oil hardening powder to your hot oil.
Whisk well and it should all dissolve.
After about 30 minutes, it will turn into a hard gelatin-like consistency.
You can now safely and easily throw the solid oil into the trash!
