10 Surprising Uses For WD-40

Everybody knows WD-40 is the go-to product for silencing squeaks, displacing moisture, preventing rust and loosening stuck parts. You probably have a can sitting in your garage right now. It has lots of uses, but it's no panacea. In fact, there are a some jobs WD-40 will absolutely ruin.

Use WD-40 To:

1. Lube a shovel. Spray WD-40 on a shovel, spading fork, hoe or garden trowel. The soil slides right off -- especially helpful when digging in clay.

2. Clean tile. The spray removes spilled mascara, nail polish, paint and scuff marks from tile floors, and also help you wipe away grime from the grout lines. Clean up with soapy water.

3. Scrub stains from stainless steel sinks.

4. Unstick gum. A squirt makes it easier to pull gum out of carpet and even hair. It's better than cutting out the gum and leaving patchy carpet or a bad haircut.

5. Soften leather. Oil can help break in a stiff leather tool belt.

6. Free stuck LEGOs. Your kids will thank you.

7. Erase crayon. When crayon ends up on toys, flooring, furniture, painted walls, wallpaper, windows, doors, and television screens, spray on WD-40 and wipe it off.

8. Prevent flowerpots from sticking when stacked together.

9. Get rid of rust. Spray and rub away rust from circular saw and hacksaw blades. It can also clean blades of tar and other gunk.

10. Remove goo. Unstick gooey residue from price tags, duct tape, and stickers.

But Don't Spray It On:

1. Door hinges. Sure, WD-40 will stop the squeaking, but it also attracts dust and dirt. Over time, you'll end up with ugly black streaks on your hinges.

2. Bike chains. WD-40 can cause dirt and dust to stick to a chain. Use bike-specific lubricants, which typically contain Teflon.

3. Paintball guns. WD-40 can melt the seals in the guns.

4. Locks. The spray can prematurely wear down the internal mechanisms, especially in pin tumbler locks, door locks and padlocks. Go for graphite powder.

5. iPhones and iPads. WD-40 won't repair the Home button on these devices. In fact, the spray can cause the plastic to break down on the cover. If some gets inside the electronics, it can damage plastic parts inside.

    I think I'll risk it with the hinges, I don't really care what they look like as long as they don't squeak. This is 50% of my WD-40 usage

      If they are loose pin hinges knock the pins out and use candle wax, if they are fixed pin use either graphite powder or handy oil/sewing machine oil.

      Agreed. I've never noticed any black marks, but I do have nice quiet doors.

    Serious? I've never seen WD40 do anything corrosive, I use it all the time in electronics, I spray the plugs and sockets to make sure electrical conductivity is top notch.

      I think it can break down PCBs over time. Please correct me if I'm wrong I just read it somewhere.

        You're better off using furniture polish (Like Mr Sheen, or something with Silicone in it. My dad taught me this - he's a designing electronics engineer by trade).

        In ye olden days, if you had a noisy volume control on your amplifier, just spray the pot (the switch with the coil in it) with furniture polish, give it a couple of twists and you're done. You'll get another 3-5 years of un-crackly volume adjustments.

        I'd personally never spray WD-40 into electrical/electronic devices.

          But the thing is... I'm an electronics technician, I've always used WD-40 to clean circuits, mostly plugs and sockets, but occasionally wash the board with it.. I've never known a problem... I'd use it from everything from pots to mode switches... Perhaps it is a problem and I've just never noticed.

    an alcohol is best for the home button on a iphone. I personally like the hand sanitizers, a few drops around the edge and a few hundred presses and your away.
    Also, I'll risk using WD with in doors and locks. rentals I dont care about..

    5. Soften leather. Oil can help break in a stiff leather tool belt.

    Wouldn't this dry the leather out?

      yeah i didnt agree with this one either, wd-40 is primarily a solvent, not a lubricant

    Use to keep soil off your spade.

    Do not use in door hinge because dust and dirt sticks.

    Interesting - but nonetheless, a great quick article. Nice.

    I read Lube Shovel, then thought wtf lol

    On a similar note, I have never seen a paint stripper as effective as a can of Aeroguard

    thanks Giz, this info is good.

    I use it for cutting oil on metal, and aluminum.

    I use it as cutting oil.

    7. Erase crayon. When crayon ends up on toys, flooring, furniture, painted walls, wallpaper, windows, doors, and television screens, spray on WD-40 and wipe it off.

    Spray WD-40 on my TV screen ? I'd be worried about the protective glass coating. I've seen LCD's and old CRT's ruined with Windex.

    Also great for removing ink from material (Eg. Pen that leaks in pockets)

    Works great on fishing hooks. Attracts fish too

    Back in my childhood days of being a BMX bandit I'd use it underneath my handlebar grips, as it would stop them spinning around.


    Spray a squirt onto a dry cloth, then wet the cloth thoroughly, wring it out and use to polish your windscreen or house windows. Polish off with a dry cloth and you have yourself a water repellent windscreen or window. It's much easier to clean the next time also.

    It's also good for getting rid of that stupid spray on snow people use at christmas time.

    it works wonders for killing cockroaches, spray here n there around home, they die,, hahahahaha

    Silicone lube is superior stuff. And I mean for work purposes, not for the bedroom.

    As its petroleum based, I definately would not use it on shovels or flower pots.. Its toxic, ya know..

      WD-40 is not petroleum-based, in fact, it's largely made from fish oil. Try spraying it on your fish bait - it works wonders!
