The Best and Worst WD-40 Uses at Home

Chances are, you haven’t heard of WD-40 for years. You may have a can of it hiding out in the garage somewhere, ironically growing the rust it’s well known for preventing.

It’s time to rediscover the love for this magical product.

We’ve got 8 of the best uses for WD-40 below plus 4 uses you should avoid.

So, what is WD-40?

WD-40 is a cleaning product, lubricant, and anti-corrosive solution. Its name is derived from the term ‘Water Displacement’ and the 40 represents the number of attempts the creator took to concoct the perfect formula.

It was originally developed in 1953 for use in the aerospace industry to prevent rust and corrosion.

Over the years, it became a household staple and people have been discovering different uses for its unique (and secret) formula. In fact, the WD-40 website has a section dedicated to user videos of how they use the product at home.

8 of the Best Uses For WD-40

01Driveway Oil Spots

We recommend using on a concrete driveway only. Spray the oil stains, wait a few minutes and blot with a clean rag. Stubborn stains may require a longer waiting time before you blot.

02Making Stainless Steel Shine

Getting stainless steel clean can be tough. With greasy kitchen substances and hands always on the door handles, fighting fingerprints on your fridge can be a constant job.

You can easily remove fingerprints by spraying WD-40 and wiping with a paper towel in the direction of the steel grain. This helps to avoid streaking and keeps your appliances sparkling.

03Remove Hard Water Spots

Did you know you can clean your toilet with WD-40? Spray, wait a few minutes, scrub with a toilet brush, then flush! It is so effective here because WD-40 softens the rust and lime deposits making it easier to wipe them away.

Mineral deposits from hard water build up on your shower screen and can be difficult to remove. Use WD-40 instead of your usual glass cleaner and see how you go. Make sure you open a window while you clean; good ventilation is recommended while cleaning with WD-40!

04Fix a Stuck Zipper

Don’t throw those favourite jeans or boots away just yet. Whether it is stuck or just being stubborn, use a little WD-40 on the area. It should do the trick!

05Lubricates Sticky Drawers and Jars

Just a light spray on the slides of troublesome drawers will make them move a little smoother. Same goes if you’re having trouble opening up jars, too.

06Removes Crayon and Ink

If you’ve got little ones at home, you’re no stranger to a crayon or ink stain on your walls or carpet. Crayola itself recommends WD-40 for treating crayon stains on fabric. Got crayon on the walls? Give it a spray, wipe with a rag, and the crayon marks are gone.

Ink on the carpet? Spray with WD-40, leave for a few minutes and sponge with soapy water. With a clean sponge, absorb up as much of the WD-40 and soapy water as possible. Make sure the carpet dries completely.

07Noisy Door Hinges

You know that squeaky sound that older door hinges can sometimes make? WD-40 makes easy work of sorting those squeaks out. Just spray a little on the hinge itself and test it by moving the door back and forth. You’ll need to spray a little more if you can still hear a squeak.


If your scissors are a little rusty and rigid, spraying some WD-40 on the blades will loosen them right up.

4 Uses We DON’T Recommend

Don’t use it to lubricate your laptop or computer keyboard as it may damage the plastic elements.

Don’t use on silk as it will stain this delicate material.

Intriguingly, people have actually tried to use WD-40 as a lighter fluid because of its flammable properties. This is definitely a terrible idea, for obvious reasons!

Don’t use it for medical purposes. It is an ongoing myth that WD-40 treats arthritis, which the WD-40 company itself says is completely false.
