unless you have modern "spray in any position" cans, which do not need this upside down cleaning, because you can't even if you wanted to, just sprays paint upside down.

i always remove the tip from the spray can as soon as it's empty, blast it with the compressor, throw it into your spray can tips bin, next time a tip is clogged beyond cleaning you will find a fresh ready to go tip in your spare can tips bin, after 20 years you will have a tip to fit all brands and types of cans.

I have not had one clogged paint can in 10 years. Turn upside down, spray for the count of 1,2,3.........IMMEDIATELY wipe nozzle hole with a rag. Must wipe good on nozzle hole and surrounding. Don't tilt nozzle while wiping or it will spray again. Can't wait to do this, must be done right away. Even during coat "waits".

A needle-tip blow gun and 100 PSI of air pressure has cleared a bunch of clogged rattle can tips for me, especially after an overnight soak in thinner.

Most spray cans are shockingly bad today. If I have a paint color I want to keep and the can goes bad (happens frequently), I will let the can sit still for a few hours or overnight. Then using a sharp awl I'll carefully poke a tiny hole right where the top piece connects the can portion, pointing it away from me. Let all the pressure release and then use an old style beer can opener to make a larger opening and pour everything into small jar (like a pimiento jar). If the nozzle still works, you can do the same thing by turning the can upside down, but often the dip tube gets clogged. When that happens I've learned that can isn't ever going to work right again. Once I have the paint in the jar, I can mix it thoroughly, pour through a strainer into a little airbrush, thin a bit if needed and spray away. Even a cheap Harbor Freight ($10) airbrush will do a much better job than a spray can, is easily adjustable and you can clean it in a wink. The one I have also came with a 3 ounce jar and with no more overspray than it produces, you can paint a while with it.

Another tip: Have a color that is just about right but not quite perfect? Need a bit more white, red, yellow, etc in it? Or do you have a color which would be perfect if it only had silver or gold in it? Get two cans of paint both made by the same company (say Rust-Oleum or Krylon). Drain both into jars and mix as needed. Chances are very good they'll be compatible. Try a bit with a brush until you're happy with the color...then paint with your airbrush.

Jon, I've actually thought about putting the paint from a rattle can in a different container. I actually bought a rattle can of Rustoleum and when I went to use it, it was bad right away. Pushed the button and nothing. The nozzle is clean as a whistle, so the valve inside the can must be fubar.
Rustoleum has a guarantee, and I tried sending them a thing with the code on the can for them to replace it, but never got a response. That can will get the pressure release trick when I get around to using more.

Harold46 and Bartamos are spot on. I always wipe the nozzle with thinner after painting and I also have a bottle of thinner that I drop the used nozzles into. I have several variations of the nozzles if needed.

Shake shake shake it is the secret to spray cans. One other thing I do when the weather is cold is to put the can in a sink of warm water for about 10 minutes and it makes a world of difference.....and did I say shake shake shake it?

Back some time ago, when the "new" nozzles came out that you do not have to turn the can up side down to clear, I bought a case and had some problems with the nozzles. I called the customer line and gave them a scowling over the situation and they sent me an envelop full, about 20, new nozzles and an apology. Still have them.

Hot Rod Lincoln is also onto a good idea. I haven't had to use compressed air on a paint nozzle but use it on cans of stuff like WD40 when there is lubricant still in the can but no propellant. I put the caps off and using my air nozzle with the small tip I shoot a shot or two of air in the can and can use up the rest of the liquid.......and NO, I haven't blown up a can...yet?!!
