Is your sink clogged or blocked with fats and oils? Here is what to do to unblock your drain from oils and fats quickly.

Your kitchen sink gets used every day, and the risk of your sink drain being clogged up is relatively high, considering what is being drained down the pipes.

During washing and cooking, you are bound to end up washing down food items and fat and grease from cooking products which can impact clogged sink drain.

This can have a severe effect on your drain pipes. The build-up of oils and fats will create a barrier inside your pipelines which can cause a barricade. Water will struggle to flow smoothly down the sink drain, leading to foul odours and potential flooding.

Having a blockage in the kitchen sink is not an ideal issue to go through and can cause major plumbing problems for you. Not dealing with clogs in your drain pipe may lead to costly repairs in the future.

Sink Clogged Fats Oils

What happens if oil goes down the drain?

Oil or grease from cooking oils usually are thick inconsistency, and grease clogs 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 and cause a clogged drain.

Once oils and fats have been in your drains for long enough, they can build up a stink that needs to be fixed. It’s essential to get onto this quickly.

Your drainage will be filled with clogs, restricting water flow and creating a problem in your household. Water will eventually back up out of the sink, and you are at risk of water damage to your home. Your clogged sink may even attract drain flies.

Not to mention the frustration of a slow draining sink and stinky drain area! We can show you how to take care of a drain filled with oils and fats. No need to call a plumber in Sydney. These steps and tips can be carried out simply with household products.

How do you get rid of blocked drain fat?


If you can tell that your sink is backing up or is sluggish, then a good old fashioned plunge is very effective. Using a plunger works by using pressure and suction.

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

For an environmentally friendly drain cleaner, you can use a combination of vinegar and baking soda. You will be able to find these items in your kitchen. All you need to do is pour 1 cup of boiling water down your sink. You are followed by 1 cup of baking soda and 1 cup of vinegar.

Cover the drain with a plug and let the mixture sit for 5 minutes. Pour 1 cup of boiling water down the drain to finish off. Test your sink to see if the clog has been removed.

The two products mix to create a reaction that eats away at oils and fatty substances. This method is perfect as you don’t have to use harsh chemicals to harm the environment.

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.
