Learn how to stop squeaky hinges at home with oil and wire wool in simple steps. Spray some WD-40 lubricant to the hinge and open and close the door a few times. Use a spray tube to avoid the oil being wasted or even you can use cooking oil. If the hinges are still squeaky remove it completely and rub it wire wool, fix it back and spray the lubricant or oil. You can also rub it with soap instead of wire wool. If you still have the squeaky problem replace the hinge with a new one.
