How To Unblock Clogged Aerosol Cans — Ways That Work When clearing an aerosol of a blockage and bringing it back into service, there are many techniques available to consumers that differ by their effectiveness and convenience. Below, we list three different ways to approach the subject:
Pressure Release Technique
Turn the can upside down and try to spray again after you have shaken it for about a minute. This technique relies on the increase of pressure in the can to knock loose any fouled stuff in the nozzle. If this first try is not enough, taking the nozzle off and passing a small pin or needle into the spray hole might rid you of lingering dirt. This method is simple and it usually shows results fast.
Soaking Method
A more effective approach is to soak the nozzle in a solvent like mineral spirits or paint thinner. Soaking the nozzle overnight with dryed paint and/or dirt will soften up making it easier to clean.cleaning aerosol nozzles (ad) Clean up the nozzle opening with a thin wire or sewing needle once you have soaked it. This is especially effective for the clogs that are harder to get rid of by just using this pressure method.
WD-40 Alternative
WD-40 works well for a quick fix, The first is to take the clogged nozzle off the aerosol can, and clamp it on a WD-40 canister. With repeated spraying of the WD-40 can handle, the propellant is moved through every time you press it down which aided in loosening up any debris caught in that original nozzle. Not only is this option reliable, it also offers a level of convenience to those who have WD-40 lying around the house.
In other words, if one method fails to work, you can always rely on another: whether the pressure, soaking or going for alternative products such as WD-40. They each have their benefits depending on the severity of the clog and what you have access to.
