7 Ways You Can Use WD-40 In The Bathroom

WD-40 is known for fixing squeaky hinges and loosening stuck bolts, but it can also be surprisingly useful in the bathroom of all places. With its water-resistant and grime-cutting formula, it helps tackle a range of small but frustrating problems that pop up in any moisture-heavy space. Here are just a few of the things it can tackle in the bathroom.

Clean Soap Scum Off Shower Doors

Soap scum clings to glass and dulls the surface over time, but WD-40 can help break it down without much scrubbing. Lightly spray it over the door, let it rest for a minute or two, then wipe it clean with a soft cloth. It leaves the surface slick and less likely to attract buildup right away. Follow up with a mild soap and rinse to remove any excess.

Unstick a Jammed Toilet Handle

Over time, the toilet handle can become stiff or stuck, especially if there’s corrosion inside the tank. A short spray of WD-40 on the moving parts, including the chain and handle joint, can help things move smoothly again. Let it sit for a few minutes before testing. If the problem keeps coming back, it might be time to check for rusted parts that need replacing instead.

Remove Hard Water Stains

Faucets, showerheads, and handles often develop white or greenish crusts from hard water. A small amount of WD-40 sprayed directly on the surface can help loosen this mineral buildup. After a few minutes, wipe the area with a cloth to reveal a cleaner, shinier finish. This works especially well on chrome and steel. Always rinse with warm water afterward to remove any residue.

Make Sliding Drawers Glide Again

Bathroom drawers, especially those made of wood or metal, often get sticky from moisture, grime, and general wear. A careful spray along the sliding tracks can help them move more easily again. Open and close the drawer a few times to spread the lubricant, be careful not to spray too much, and wipe off any excess to avoid a greasy mess.

Remove Rust from Shower Caddies and Metal Fixtures

Shower caddies, wire baskets, and other metal accessories are especially prone to rust since they’re near water constantly. WD-40 can help dissolve small rust spots and protect against more. Spray directly on the rust, wait a few minutes, then scrub gently with a soft brush or cloth. Rinse and dry the item well. With regular use, you can keep these items looking cleaner for longer.

Loosen a Stuck Showerhead

If you’re trying to replace or clean your showerhead but can’t get it to budge, WD-40 can help loosen the threads. Spray it around the connection where the head meets the pipe, wait a few minutes, and then try again with a wrench. This can help you avoid stripping the threads or cracking the fixture from forcing it too hard.

Prevent Fog on Mirrors Temporarily

Foggy mirrors can be annoying, especially when you’re in a hurry. A small amount of WD-40 sprayed on a soft cloth and lightly wiped over the mirror surface can temporarily prevent it from getting as foggy. It leaves behind a thin layer that resists condensation, so none of it sticks. Don’t spray it directly on the mirror, and use this only occasionally, as frequent use may lead to permanent streaking.
