How To Clear A Blocked Aerosol Can
Aerosols. Brilliant when they work well, but what about when they don't? Oh, the frustration! We have a massive range of aerosols from spray paints to food-safe grease. So if you're unsure how to get the most from your cans, keep scrolling for our tips and tricks on how to use an aerosol spray can.
Eliminating this risk is about how you take care of your aerosol throughout the life of the can. These simple steps take seconds after use and can save you time and the hassle of replacing your product further down the line.
The importance of shaking beforehand, vigorously, is hugely underrated. Especially if the product is thicker or has been in a colder temperature. If you don't shake up your cans, the contents and propellent won't mix and you can end up with a blocked aerosol can.
If that happens it's likely to clog up the straw or use up propellant before the rest of your content. Speaking of colder temperatures, the heat from your hands will help loosen the particles. This allows for a much easier user experience no matter if you're using spray paint or grease.
Even more underrated, holding your can upside down and spraying until there is no more content spraying out. This clears the nozzle and the straw, preventing content from settling in small, hard to reach areas.
Also, we recommend you use a sharp object to clear the nozzle, preventing blockage or the product drying and reducing the efficiency of spray.
It's always worth keeping spare nozzles around just in case you do experience a blockage in this area, you have those to hand without having to invest in more products.
If your aerosol has unfortunately blocked already and wont spray, here's a few top tips we have tried and tested:
- Hold the can upside down and spray; this should release some of the pressure
- Take off the nozzle - there may be a build up of matter here, so remove this with a sharp object like a pin, or it is sometimes worth washing nozzles in water to get rid of the most obvious build-up
- Continue to shake in between clearing nozzles and straws, this helping with mixing
If you are continuing to experience issues, it's probably best to move to the next can and follow the correct procedures.
