How to Get a Rusty Toilet Seat Off

Replacing a toilet seat seems like a simple job, until you realise the bolts are rusted. Metal toilet bolts rust when exposed to water and become difficult to loosen. Compounding the problem, limited access makes it a challenge to gain enough leverage to free the bolts. With the right tools, you'll be able to remove that old toilet seat.

Flip open the cap on each of the two toilet seat hinges with the slotted screwdriver, exposing the bolt heads. Spray penetrating oil on the bolts and allow them to soak for the amount of time recommended by the oil manufacturer.

Turn each bolt counter clockwise with the screwdriver while holding the nut stationary with the adjustable wrench. If the bolts don't loosen, you will need to cut them off.

Lift the toilet seat to gain better access to the bolts. Apply the duct tape to the toilet, directly in front of the bolts, to protect the porcelain.

Wrap the end of the hacksaw blade two to three times with duct tape to make a handle.

Slide the hacksaw blade between the hinge and the toilet. Saw through the bolt while holding the nut steady with the adjustable wrench. Repeat this process on the remaining bolt.

Remove the toilet seat and clean up any debris. Wipe off any remaining penetrating oil with the damp rag.


Use nylon toilet bolts to prevent this from happening In the future.


Wear eye protection when using a hacksaw.
