How to Keep Toilet Seat Screws from Rusting

Metal screws on a toilet seat can often rust, causing unsightly stains. To prevent the screws on the toilet seat from rusting, fill the holes with tub and tile caulking, then use a putty knife to level the caulking and allow it to dry before closing the lid.


  1. In reply to Paul’s comment “how do you remove the toilet seat if you have hard caulk covering the screws?”

    Good caulking is silicone, and it never gets hard. Just poke the screwdriver through it or twist & dig it out, it’s like hard jello. Just in case the caulk is cheap and does get hard, it will be much more brittle and probably almost falling out anyway, again poke & dig it out with a small screwdriver &/or utility knife. You’re lucky if caulking stays where it’s supposed to!

  2. You should remember that the screws on the bottom of the toilet SEAT don’t rust because “they’re over the water” in the bowl below. They rust more than the others because they are exposed to (…sorry…) the “splashing” of the salt in urine being (hopefully) squirted into the water in the bowl… especially by “little boys” with notarious aim…. Girls and women put the seat down (and while there may be some splash, as we learned in physics class “to pour acid into water, not water into acid”, what splashes upward from the bowl is generally bowl water, not “acidic” urine.
