Fix Squeaky and Sticky Bathroom Cabinet Hinges

Squeaky cabinet hinges are one of those small annoyances that nag at you every time you open the medicine cabinet or vanity. The sound comes from metal-on-metal friction, and it's often worse in humid bathrooms where moisture gets trapped in the hinge barrel. Sticky hinges—where the door resists opening or closing smoothly—usually mean dust, soap residue, or mineral deposits have built up inside the hinge. The good news is both problems are simple to diagnose and fix without replacing anything. A can of penetrating oil and five minutes of attention will restore most hinges to silent, smooth operation.

1. Identify which hinge is causing the problem. Open and close the cabinet door slowly while listening carefully. Most noise comes from the top hinge. If the door sticks, open it fully and try to move it up and down slightly to feel where the resistance is. Sticky hinges often bind partway through their swing rather than squeaking throughout.
2. Clean debris from the hinge barrel. Use a small brush or old toothbrush to scrub away dust, dried soap, and mineral deposits from the hinge barrel—the cylindrical part where the pin sits. For stubborn buildup, dampen the brush slightly with white vinegar and scrub the barrel and pin thoroughly. Wipe away debris with a dry cloth. This alone often fixes sticky hinges.
3. Apply lubricant to the hinge pin. Spray a light penetrating oil (like a general-purpose machine oil or silicone spray) onto the hinge pin and let it soak for a minute. Work the oil down into the barrel by opening and closing the door a few times. Use only a small amount—excess oil attracts dust and makes hinges dirtier over time. Wipe away any drips with a cloth.
4. Check and adjust the tension screw. Many cabinet hinges have a small screw on the hinge body that controls tension. If the door feels loose or sloppy, tighten this screw a quarter-turn with a screwdriver. If the door is hard to open or won't stay in position, loosen it slightly. Make small adjustments—these screws are sensitive. Test the door after each adjustment.
5. Test the full swing and listen for remaining noise. Open and close the cabinet door through its complete range a dozen times. Listen for squeaking and feel for sticking or resistance. The hinge should move smoothly and silently. If noise remains, the hinge barrel may have internal damage or corrosion that can't be fixed—plan to replace that hinge.
6. Repeat for the second hinge if needed. Most cabinet doors have two hinges. If the second hinge is also squeaky or sticky, repeat the cleaning and lubrication process. Bathroom cabinet hinges often accumulate moisture at the same rate, so both may need attention at once.
7. Plan hinge replacement if the problem persists. If the door still squeaks or sticks after cleaning and lubrication, the hinge barrel is likely corroded or damaged internally. Note the hinge brand and style, take a photo, and order a replacement. Most bathroom cabinet hinges are inexpensive and install in minutes—remove the door from its hinges, unscrew the old hinge, screw on the new one, and rehang the door.
