What happens if oil goes down the drain?

Oil or grease from cooking oils usually are thick inconsistency, and it can solidify into fatty deposits once it is cooled. These will stick to pipes and drain ways. And the more cooking oil or oils such as bacon grease that is washed down the sink, these fatty deposits can grow over time.

Cover the drain opening with the plunger cup, and whilst holding the handle stick with both hands, create an up and down motion (make sure always to cover the drain opening). The built-up suction and pressure will move the clog towards the drain opening. You may have to repeat this a few times.

Baking Soda and Vinegar

How do you prevent a greasy sink?

The best rule of thumb is to not pour cooking oils, grease or fatty liquid down your sink drain. These oils harden when they cool down, and since cold water travels through your pipes, any fat oil substance stuck on your pipes will solidify and build up over time.

The only way to properly dispose of oils is to pour them into a bag or container and put them into your garbage unit. This way, the substance won’t get into contact with any other liquid and cause a big mess with your pipeline.
