If your kitchen faucet nut has become stuck, you may need to remove it. You may use penetrating oil to help loosen the rusted nut quickly. The oil will also loosen any corroded threads or joint. This way, you will be able to remove the stuck nut without damaging the faucet.

Remove the nut

If you are unable to remove the nut, you may try heating the part with a hairdryer. By heating it, the solids in the nut will expand and break away from the housing. You can then use a wrench to remove the screw. Be careful not to touch the heated part of the nut while attempting to remove it. Make sure to shield the area with flame-resistant fabric.

If you still can’t remove the nut, you may use a plumbing wrench to loosen it. The wrench should have a long pole and jaws facing counterclockwise. The jaws should automatically lock onto the faucet nut. If the nut is too difficult to loosen, you can use a propane torch to help heat the nut. Once the nut is removed, you can either repair or replace the faucet. If you have an extremely old faucet, you may have to cut the nut to remove it.

Use an acid-based cleaner

If you are unable to free the stuck nut with a wrench, you can use an acid-based cleaner. After letting the cleaner soak for a few hours, you should then use a wrench to free the nut. If you are still unable to loosen the nut with a wrench, you can use a wire brush to loosen the mineral deposits around the nut. You can also use penetrating oil to loosen the nut. It is recommended to leave the oil on the nut for at least 24 hours to get the best results.

Another option is to use a stubby screwdriver. Depending on the configuration of your sink, you may need a longer screwdriver. You should start by tapping the nut counterclockwise to break the calcium bonds that hold it in place. Make sure you do this carefully because the nut is very hard to remove.

Use a proper wrench

When you have a stuck black and copper kitchen tap nut, the nut might have become frozen in place. This can be caused by corrosion and mineral buildup. If you have a new faucet, it is unlikely to experience this problem. It is also not uncommon for the nut to become overtightened. However, this can cause problems with the faucet, so it’s best to use a proper wrench to avoid further damage.

If the nut is completely stuck and you are not able to remove it with a screwdriver, you can try to pry it apart using a metal stick. If that doesn’t work, you can also try hammering it. This way, you will know whether the nut is totally stuck or is just too tight for you to move it.
