Re-using cooking oil

Never allow any sort of oil down your sink, especially lubricating oils, or cleaning oil. Not only is this damaging for your drain(will stick in your drain when it cools and forms a very hard plug), it is also very bad for the environment.

You should also avoid putting any moisturizer, baby oil or oil based soap down your sink. Throw them away by putting them in a container and in the bin.
