Try turning the aerator counterclockwise with your bare hands. In most cases, it will be removed. But if it is slippery or you cannot apply pressure, then you can pick up the silicone jar lid and try to remove it.

If both of these situations fail, then you can use an adjustable wrench or pliers to remove the aerator. But remember, don’t apply too much pressure. It may scratch your faucet or even break it. To protect the aerator from scratch, please wrap a cloth or towel around it.

What if my aerator is inside the faucet? This situation applies to newer faucets or brands like Delta. Therefore, to remove the aerator, you must use a tool that can open it.

After removing the aerator, you can see the dirt particles on the top of the screen. First, remove the gasket and clean the aerator in tap water. Before cleaning, put a towel or cloth on the sink to block the hole to prevent the loss of screws or small objects. Now, gently push the centre of the aerator with your thumb, which will force the restrictor to enter easily.

You will notice that there are two screens below and above the restrictor; one is metal, and the other is some kind of plastic. But remember where it is placed because you must put it back in exactly the same order. Take a toothbrush to clean the net, aerator and faucet. If you are not satisfied with the cleaning and want to make sure that there is no dirt in the restrictor, you must open it and check.

Step 4: Reattach the Faucet

After finishing all the steps, now you can install the parts according to the location and connect the aerator to the faucet and drain the water. You will notice that the restrictor is working properly, and you will get the required water pressure.
