Why can’t I empty all the product in my aerosol can?

For information about product evacuation issues and how you can get the entire contents out of the can, please watch our “Why won’t my can of WD-40 Spray” video here.

For further information, see details below.

Since product “evacuation” problems are common throughout the aerosol industry, they can affect some of the products we produce. If you are having trouble with an aerosol can not spraying, please try this brief troubleshoot:

  • Twist the nozzle ¼ turn and try again. Turning the nozzle realigns the dip tube in the can.
  • If turning does not work, please try another ¼ turn. Continue to move it around a bit until liquid sprays out.

If this still does not work, here are some tips to prevent this from happening going forward:

  • Hold your can in an upright position whenever possible.
  • Take care when handling and transporting cans and be careful not to drop or aggressively shake the can.

Can WD-40® Multi-Use Product be used for my arthritis or joint pains?

WD-40 Company does not list this as an official use and we do not endorse it.

WD-40 Company makes no medical claims for WD-40® Multi-Use Product. We know no reason why WD-40® should be effective for arthritis/pain relief. WD-40® is formulated to be a light lubricant, penetrating oil, and water displacing corrosion preventative. It contains petroleum distillates and should be handled with the same precautions for this type of material. It does not contain DMSO. We have never recommended the use of WD-40® for medical purposes. Originally, WD-40® was created as a rust-prevention product for use in the aerospace industry, to protect the outer skin of the Atlas Missile from rust and corrosion. It is also not recommended because of the possibility of skin irritation.

Is WD-40® Multi-Use Product conductive?

No, WD-40® Multi-Use Product is non-conductive and its dielectric strength is up to 38,000 volts per inch. WD-40® is a non-conductive liquid that displaces moisture. It works by quickly drying out electrical systems to eliminate moisture induced short circuits.

This includes Acetal, neoprene/hard rubber, HDPE, PPS Copolymer Polysulfone, Teflon, Viton, steel, galvanized steel hot dip, electroplated, copper, brass, magnesium, nickel, tin plate, titanium, and zinc.

WD-40® does not contain silicone and is safe to use on surfaces prior to painting.

Does WD-40® Multi-Use Product contain fish oil?

No, WD-40® does not contain fish oil. Consumers have told us for years that they’ve caught some of the biggest fish ever after protecting their fish hooks and lures with WD-40®. We believe this legend came from folks assuming the product must contain fish oil since it appears to attract fish. Despite the stories, this is simply not true.

What is the shelf life of WD-40® Multi-Use Product?

WD-40® is a product which is designed and manufactured to a high degree of specifications. The product should continue to perform as expected for an almost indefinite period of time. However, actual performance can be affected by the longevity of mechanical items such as the valve assembly on aerosol cans. As such, the shelf life is considered to be 5 years from the date of production; however, product will often dispense and perform as expected for considerably longer.

Are WD-40® Multi-Use Product Aerosol products flammable?

Yes.

How long does WD-40® Multi-Use Product last after application?

While this may vary depending on the application, WD-40® Multi-Use Product remains effective even after it appears to dry. The corrosion and rust protection ingredients remain adhered to the surface. External conditions may, of course, require additional applications of WD-40® Multi-Use Product for maximum protection.

What is the propellant in WD-40®?

WD-40® uses CO2 as a propellant, as it’s less flammable and safer for aerosols. The CO2 also allows 97% of the liquid out, so you get the most out of your WD-40® cans as opposed to hydrocarbon-based products. Be sure to point the spray nozzle toward the dot on the top of the can to ensure that the can fully empties.

Can WD-40® remove rust?

WD-40® helps remove rust by breaking down the bonds between metal and rust. Spray the rusted surface with WD-40®, enough to thoroughly soak the area. Allow it sit for up to 10 minutes. Clean the rusted item with a wire brush. With the rust loosened, the brush should clean away most of the corrosion. Brush the surface until you’re satisfied you removed most of the rust and wipe any remaining residue. Ensure to end by spraying with WD-40® to protect the surfaces from future rust.

Why is my WD-40® liquid a milky colour?

Separation of one of the corrosion inhibitors can be accelerated by colder temperature. Shaking the liquid will correct it back to its normal characteristic.

Note, this milky colouring problem is applicable to all lubricants but is typically seen in the WD-40® Bulk varieties.

Are WD-40® cans recyclable?

Yes – you can place your empty aerosols straight into your recycling bin, along with other aluminium or steel household waste. Do not pierce, squash or separate them. You can also find out if your local council recycles empty aerosols and most do. The majority of councils accept aerosols in their kerbside collection schemes and at waste disposal sites.

Does WD-40® Low Odour work the same as the original can?

Are the heads of the WD-40® EZ-REACH transferable to other cans?

No – these heads fit specifically to individual cans and cannot be transferred between different cans. The actuator is applied to the can under a controlled environment within the factory and any attempts to change the actuator can damage the valve.

Do you need to tilt the WD-40® EZ-REACH can to use it? Can the can be held upside down and still be used?

You do not need to tilt the can as the straw can be bent at any angle you require, allowing you to spray on hard to reach areas.

Does WD-40® Specialist® Lawn & Garden kill bacteria to prevent cross contamination in my garden?

No, WD-40® Specialist® Lawn & Garden does not kill bacteria to prevent cross contamination between certain plants in your garden.

Can I use the WD-40® Specialist® Lawn & Garden range on my garden power tools as well as hand tools?

How does the WD-40® Specialist® Lawn & Garden range make my garden tools last longer?

Fertilisers and other chemicals that you use in the garden contribute to the rapid corrosion of metal parts on your garden tools and equipment. By preventing this corrosion and protecting your tools from rust, WD-40® Specialist® Lawn & Garden will save you time and money in the long run.

Does WD-40® Specialist® Lawn & Garden protect wood and rubber as well as metal?

If you use WD-40® Specialist® Lawn & Garden Water Protective Silicone it will prevent residue build-up and prolong the life of your rubber handles and plastic surfaces. Note for rubber, always test surfaces first.

How should I store my tools in winter when I am not using them?

For all of your smaller hand tools, find an unused pot that is large enough to fit your smaller hand tools in. Fill the pot with clean dry sand 5cm from the top. Spray a substantial amount of WD-40® Specialist® Lawn & Garden Lubricant on the sand until it’s moist. Insert the hand tools into the pot so the moist sand covers the metal parts. Store the pot indoors in a cool, dry area.

For all your other hand tools, make sure you clean them properly first with WD-40® Specialist® Lawn & Garden Cleaner, and allow the product to penetrate before agitating with a brush or cloth. Once clean, spray with WD-40® Specialist® Lawn & Garden Lubricant and let it soak for best rust protection. Store under cover for best results.

For all your power tools, remember to disconnect first, then clean and spray with WD-40® Specialist® Lawn & Garden Heavy Duty Grease and wipe after spraying. Store undercover, away from the weather and elements. This will prevent rust from destroying your tools and will ensure they are still working with ease next time you’re gardening.

What if my garden tools already have rust on them?

If rust has built up on tools, spray with WD-40® Specialist® Lawn & Garden Powerful Foaming Cleaner. Allow the foam to penetrate and wipe clean (scrub with a brush if required). Then clean metal surfaces using WD-40® Specialist® Lawn & Garden General Use Lubricant. Old and stubborn rust may require the use of a steel brush. To protect from future rust, saturate the area and do not wipe off.

Do I have to scrub my hand tools with WD-40® Specialist® Lawn & Garden Cleaner to shift dirt and deposits?

If you have been cleaning your tools regularly, or they are brand new, you shouldn’t need to scrub your hand tools to shift dirt or deposits. Simply rinse the soil off digging tools with a garden hose or outside tap and spray some WD-40® Specialist® Lawn & Garden Cleaner on your tools to help break down resin, sap, dirt, oil, grease, residue and deposits.

If there is a build-up, you may need to rub with a brush or a cloth to help shift the dirt and grime. Wash off any excess liquid and dry thoroughly.

WD-40® BIKE

cats-bike
Why should I avoid taking the chain off to clean it?

If your chain needs cleaning, try and do so with it still on the bike. Breaking your chain repeatedly weakens the link and over time can lead to failure. If the chain uses a master link or a “quick link”, avoid breaking it unnecessarily, as most modern “quick links” (mainly on 10-speed chains) are single use only.

My chain is completely covered in gunk. What’s the best way to degrease it?

To properly degrease a chain, put your bike on a work stand and shift into the largest chain ring and the middle of the cassette. Use WD-40® BIKE Heavy Duty Degreaser on the chain and chain rings. Scrub off deep-set grime with a stiff brush. Wet a sponge with water and add some WD-40® BIKE Heavy Duty Degreaser to the centre. Fold the sponge in half and make a chain sandwich. Back pedal and get the chain to foam. Rinse off the foam and wipe dry.

How should I apply lubricant to my chain?

When lubricating your chain, drip the lubricant onto each individual roller instead of just applying a stream along the entire length of the chain. Lubricant does nothing for the outside of the chain; it only works to reduce friction and keep dirt out of the inside of the rollers. Be sure to run a rag over the chain after letting the lube set for a while. Any lube left on the outside of the chain will be a magnet for dirt and grime.

What is Dry Lubricant used for?

WD-40® BIKE Dry Lubricant isn’t just for chains. It’s great for brake pivots, derailleur pulley bolts, main parallelogram pivots and pedal retention springs. If you’ve just finished a ride, drop a spot of lube inside brake and derailleur cable housings to keep things moving freely. Remember to wipe off excess lube.

The squeezie bottle of WD-40® Multi-Use Product is great, but what do I do with it?

The original WD-40® Multi-Use Product is great for clearing out and freeing up stiff, grimy shifter internals. It is the perfect revitalizer for your shifting system.

I usually just hose my bike down when it’s dirty. How should I use the Foaming Wash?

When washing your bike, don’t forget the underside of the frame and fork where the heaviest gunk resides. Spray your entire bike with WD-40® BIKE Foaming Wash, from top to bottom. Use a soft brush and work the product into all the nooks and crannies to get the dirt moving.
