Clearing the opening with warm water

Clean the nozzle’s opening with warm water. Dampen a clean rag. Wipe the nozzle opening lightly with the soaked rag. Test the spray paint on a scrap material piece to make sure it sprays without any blockages

When you are finished painting, there may be some inconsistency in the finish. However, if you spill some water or other liquid into the paint can, this will result in a much more consistent finish.

Cleaning and wiping with thinner

This can be a messy process. It would be best to use goggles and gloves when doing this! Remove the nozzle tip, clean it with paint thinner, then hose down the area you were spraying down in the first place.

Be sure to test a small section of towel or other material you don’t mind getting dirty for color accuracy when using your spray paint on it. In order to remove the nozzle easily, we turn it counter-clockwise until it slides out.

Preventing method for clog

This tip is from my personal experience which I initially shared with my painting fellas and they found it helpful that’s why I will advise you on this method of mine to prevent future clogs which can be occurred from spray paint nozzle.

Spray paint wastes paint the moment it starts to clog up so if you want to save some, then you need clear out the nozzle and replace any caps before you store them otherwise.

To do this: Turn the bottle upside down, so it’s in an upright position. Then press down on the nozzle and leave it that way for a few seconds until a mist-like substance comes flowing out.

Unclogging method for nozzle

The first, and most obvious step, is to simply soak the clogged nozzle in paint thinner.

Much like a clogged sink that has accumulated a lot of soap scum, this will loosen the blockage in your nozzle and allow the flow of liquid to freely proceed past any possible debris inside.

If this measure does not clear out the problem you may find it necessary to remove the nozzle from its housing and attempt to pick at any stubborn bits of gunk with a small needle or toothpick before repositioning it back into its original location.

Remove softened paint

Make sure you use a pair of protective gloves as well as rinse the nozzle under water. Remove and clean the paint nozzle to purge the softened-up paint.

Be careful not to have any other lethal objects inside it because this could damage the nozzle’s tube.

Apply aerosol lubricant on the nozzle

If you’re having trouble with your spray paint nozzle getting clogged, the first thing that might help is to clean it out by spraying some aerosol lubricant into the opening.

If this doesn’t work, try spraying some right into the nozzle itself and wait a couple minutes before you try using it again.

If this happens again, then spray some lubricant directly on both the opening and around the outside of the filter. Try using it again as needed until your bottle isn’t empty yet.

Clearing method for a hair spray nozzle

If your hairspray is clogging, the nozzle may be a problem. In order to reduce problems with the nozzles and spray system, it’s a good idea to clean the nozzle from time to time. First, remove the nozzle from the can and wash it under clear running hot water for 5 minutes.

Then let the nozzle dry thoroughly. Usually after this treatment you’ll find that there’s still some dried bits of spray stuck inside – these can be removed easily with a needle or cocktail stick without damaging the spray system further.

First of all, wash the extra hair and spray off your fingers with soap and water. Then cover both hands with rubbing alcohol.

Bathe in it as long as it feels good on your hands! Take an old toothbrush, dip it into the rubbing alcohol, and brush vigorously to remove whatever is blocking your bottle from giving you those lovely sprays.  

Replace the nozzle back into hair spray bottle and attempt to spray once more.

Preventing method for a hair spray nozzle

Prevent your hair sprays from clogging by simply cleaning the nozzles off regularly. Add a bit of water to a rag and wipe down the nozzle after every use, or even in between uses if you feel it’s getting bogged down. This will keep the nozzle clean and free from product build-up.

Depending on how often you decide to use the product, you should be cleaning these types of tips several times a week (or more!).

It’s also a good idea to write an expiration date on your cans so you can monitor when you might need to replace them because this will only work until that date!

If you still find yourself dealing with clogged nozzles, try replacing the spray bottles and checking for any damaged caps.


I have been using spray paint for my art projects and I wanted to share my experience with cleaning spray paint nozzles. I would say cleaning spray can nozzle is the least favorite aspect of using spray paint for me. It’s often a messy and frustrating process but you can definitely avoid it if you know the right techniques. What you need is rubbing alcohol, white paper, clean cloth, elastic band and a pinch of patience.

When I paint with a spray can , I make sure to shake the can frequently and turn it upside down and let the paint drain back down through the nozzle. That way, the paint doesn’t have time to dry around the nozzle. The more paint that dries around the nozzle, the more likely you are to get clogs.

There are various reasons why your spray paint gets clogged. When you’re using spray paints, make sure you shake the can well to mix the paint’s solids and the liquid. You should also try to avoid using paint cans which are dented or cracked. You can also try using a thinner to thin out the paint so that it doesn’t get clogged. Another way to do this is by using a spray paint filter. It looks like a glass bottle with a funnel on the top. The last way to do it is by wiping the nozzle with a clean rag before you spray the paint.

Yes, you can use the spray paint can upside down. I already tried it and it works. The trick is not to do it too slowly, if you do it too slowly the paint will start falling out of the spray can. I started doing it slowly in the beginning and it was awful. You can probably tell from the photos, I was doing it really slowly and it was really messy. I just kept applying pressure until the paint started flowing out and it worked. I used two cans of paint and it worked well.

It depends on the spray paint and on the temperature and humidity of the room. Generally, it takes from half an hour to 24 hours for spray paint to dry. Usually, it takes about six hours for spray paint to dry.

If your aerosols are not spraying, then you might have a clogged nozzle. The easiest and most common way to solve this issue is to spray some hot water into the can. You can also try using a pin to poke the nozzle, or using dishwashing soap. Make sure you dry the nozzle completely before you try using it again.
