What is WD-40?
WD-40 is a multi-purpose spray designed to displace moisture, loosen rust, and provide light lubrication. It was originally developed in the 1950s to protect metal from corrosion.
Today, it’s commonly used for small maintenance jobs around the home, from freeing stuck fittings to removing residue.
Common WD-40 Uses Around the Home
1. Remove oil stains from concrete
Spray onto the affected area, let it sit briefly, then blot with a clean cloth. This works best on concrete driveways or garage floors.
2. Loosen rust and mineral build-up in toilets
WD-40 helps soften rust or lime deposits, making them easier to scrub away. Use with good ventilation and rinse thoroughly after cleaning.
3. Remove paint and glue from skin
Apply a small amount, gently rub, then wash thoroughly with soap and water. Avoid prolonged contact.
4. Free a stuck zipper
A light spray helps loosen a stubborn zip. Apply carefully to avoid getting any on surrounding fabric.
5. Lubricate sticky drawers
Spray lightly on drawer runners to help them open and close more smoothly.
6. Remove Crayon and Ink Stains from Fabric
WD-40 helps loosen marks on hard surfaces like walls, making them easier to wipe away.
For deeper stains on carpets or lounges, a professional upholstery or carpet clean may be needed.
7. Clean fingerprints off stainless steel
A light spray helps loosen residue, making it easier to wipe away smudges and marks. Wipe in the direction of the grain for a cleaner finish.
8. Help remove oily stains like lipstick
Apply to the stain, blot gently, then wash as normal. Test on a small hidden area first.
9. Stop squeaky door hinges
Spray a small amount onto the hinge and move the door to work it in. Helps reduce noise and friction.
10. Loosen rusty scissors
A quick spray can help free up stiff blades and improve movement.
11. Remove sticky labels and residue
Spray lightly, let it sit, then wipe clean. Works well on glass, metal, and hard plastics.
12. Protect garden tools from rust
After cleaning your tools, apply a light coat to help reduce moisture exposure and corrosion.
13. Clean outdoor furniture
WD-40 helps lift grime and oxidation from metal or plastic outdoor furniture. Avoid use on fabric or painted timber.
14. Loosen stuck fittings and bolts
Spray onto tight fittings, wait a minute, then try loosening again. Useful for rusted or stuck parts.
15. Help remove tree sap and tar from surfaces
Apply to the affected area, let it break down the residue, then wipe clean. Wash afterwards to remove any remaining film.
16. Prevent rust on outdoor fittings
A light coating helps protect exposed metal from moisture, especially in coastal areas.
17. Freshen up tools and hardware
Use a light spray to clean and protect items like hand tools, hinges, and fittings.

A small amount helps loosen watermarks so they can be wiped away. Wipe thoroughly to avoid residue.
