How to Remove a Stuck Faucet Nut : Quick 7-Step Guide

How to Remove a Stuck Faucet Nut
Written by Callum Strempel

Getting a stuck nut loose can be hard. Mineral deposits can accumulate on faucets and become stuck. Corrosion of the nut can further aggravate this problem.

Once you better understand how to solve this problem, it will be easier for you to deal with it. After a nut has become stuck for a long period of time, removing or breaking it can be a challenge.

How to Remove a Stuck Faucet Nut

Tools and Materials

  • Utility knife
  • Bucket
  • Channel type pliers
  • Penetrating oil
  • Wrenches
  • Screwdrivers
  • Old rags

Step 1: Turn Off The Water

You can turn off the faucets located under your sink or turn off the main water supply.

Turn the knobs clockwise as much as you can to close the shutoff valves.

Step 2: Harsh Wire Brush

Harsh Wire Brush

As much corrosion as possible should be scraped off of the faucet joints. Corrosion will be removed, and the joints will be free to screw since there will be no corrosion.

Clear the faucet of any dirt or debris that may impede its removal. Then, rotate the nut clockwise to remove it.

Step 3: Using heat

The nut can then be heated with a dryer to make it easier to remove. As a result, the corrosion-induced bond will be broken down. You can also use a propane torch or heat gun.

Step 4: All-pervading Oil


Another option is to apply penetrating oil such as WD-40. This allows you to remove the nut more easily.

Be sure to apply it to all of the corrosion-prone joints and nuts of the faucet to loosen their grip. Let the oil sit a while to see if it begins to break the seal.

Scrub the corrosion with a brush. Then, pour white vinegar over the nut to remove any remaining corrosion.

Step 5: Wrench


To use the wrench, get inside the cabinet and access the area underneath the sink, and remove the nut holding the valve tailpipe to the sink.

To remove the nut, you must loosen the grip by rotating it counterclockwise.

Open the jaws of the wrench and hook them onto the nut. Make sure they face the direction that the nut must be turned in order to lock onto the nut.

Step 6: Acid-based cleaner

Ensure that all mineral deposits have been removed before freeing the stuck nut. Apply the cleaner to the exposed surface of the stuck nut using a rag and let it sit for a few minutes.

Make sure that the corrosion and mineral deposits around the nut are also loosened with the wire brush.

Remove all traces with the cloth. Continue to clean the nut and let it sit for 24 hours.

After soaking, try to use the wrench to loosen it.

Step 7: Hacksaw the nut

When all else fails, you can cut the nut with a hacksaw

  • Set yourself in a position where you are comfortable
  • Beginning at the nut’s top, cut vertically until the end is reached.
  • You may now use a pair of pliers to retrieve the stuck nut.

Quick Tips to Remove an Over-Tightened Nut

  • Take apart the drain trap if you need more space
  • Ensure you wait after applying oil; it takes time
  • Don’t heat a nut that is soaking in oil
  • Penetrating oils are very flammable


1. How to loosen a nut that won’t budge?

Ans. Leverage is the key to removing that stubborn bolt. It is best to use a breaker bar, socket wrench with a long handle, and no ratchet mechanism. If you have a longer lever, then you will be able to exert more force as you can lean into it via the leverage. As a result, you will be able to exert more force on the bolt.

2. What’s the best method for loosening plastic screws?

Ans. Apply rust penetrant to the screw; Liquid Wrench and PB Blaster are recommended. Wait at least 15 minutes for the penetrant to take effect. Then, spray the screw head and tap it repeatedly with a hammer. Then, use the screwdriver once more.

3. What to do if a plastic faucet nut becomes stuck?

Ans. Heat will make it easier to loosen the nut whatever method you use. Plastic should become pliable and subsequently break the nut. A calcium dissolver can also be sprayed on the nut and tap, then twist after several minutes.
