dribbling spray paint cans

Why is it so often when I grab a can of spray paint it works for a little while then starts dribbling and dripping out of the top where the nozzle inserts? Then it'll usually sputter to a stop and not work again, or if it does it continues with the dribbling.

Seems like it happens to me mostly with spray cans that have already been used, even though the nozzle was cleaned by turning upside and spraying until clear the time before. Sometimes it even happens with brand new spray cans of paint.

Why? - see murphy's law

I think that's just a by product of aerosol paint cans. Sometimes the spray nozzle cracks or whatever - in those cases you can 'steal' a nozzle out of another can. They aren't always the same so it might need to be the same brand of spray paint.

IMO the only good way to spray is to have an air compressor and gun. Rattle cans don't always work well

Try soaking it in very warm water, seems to help sometimes. Not the top of can.

Be safe, Gary

It is mostly because the can sat too long and/or wasn't shaken enough.
A trick is to store the can upside down so that if there is any settlement it will be less likely to get sucked up the pick up tube.

So how long do I have to soak it?

It sits at the store on the shelf stored right side up a long time before you buy it, not to mention all the additional time it sits in storage in the box right side up since being packed after it was manufactured. Seems like if storing it upside down prevents settlement from getting into the pickup tube then storing it upside down should be the method from the very beginning.
