The door that leads into our mudroom (from our garage) gets the most use in our house. The kids and I are in and out several times a day, I open it to recycle things and throw out the trash. We have lived in the new house for 8 months, and I have had to WD-40 the door hinges three times. After the second time, I decided to ask our builder if there was anything I could do to make the squeaking stop. They said that the door is so heavy (because it is a fire door) that over time it will just start to squeak.
Leaving the noise would not work for me. I would have to just keep oiling the hinges. Working with the WD-40 was starting to become a mess as it was getting on the wall and dripping down the trim after I sprayed it, and it made the house smell. I saw on Pinterest that you can use mineral oil for so many things, including oiling your door hinges.
I already had some under my sink (I also use this to oil my cutting boards), so I thought I would give it a try. So far, so good! The squeaking stopped immediately and it was so easy to apply! I soaked a cotton ball with the mineral oil and applied to the hinges. Super easy, no mess, and no odor. This is my new go-to for all things squeaky!! You can see I purchased my mineral oil at Walgreens (around $5). Have you ever used mineral oil? Any other tips?
