How to clean a clogged Misto oil sprayer/spritzer?
I use a Misto oil spritzer. You fill it up with oil and pump it up and spray a pan with it.
It's gotten clogged up so that it just squirts a steady stream of oil (not a spray).
Any ideas how to clean it and keep it from clogging again?
I've tried:
Soaking it on wine
Soaking it in boiling water
I'm going to try filling the bottle with vinegar and water. I've also heard that you should use regular (not extra virgin) olive oil. (Extra Virgin is apparently thicker).

After trying to use my Misto for several months and constantly cleaning it, I discovered that I could purchase small sprayers for a few bucks that work exceptionally well for oil and never need supplemental cleaning. I've one I've used for over 6 years with no issues. Sorry to say, but I recommend you toss the expensive oil sprayer - you'll never look back.
Empty the oil, half fill the can with hot tap water (150-160 deg.f.) Pump and spray. Do it a few times with fresh hot water even though the clog appears to have been removed. Empty the can, pressurize again and spray until the water residue is sprayed out. No soap, no dishwasher detergent is necessary.
The Misto is rancid after I moved across country and had everything in storage for a few months Since I use my second sprayer for lemon juice I filled the Misto with lemon juice and the yucky oil smell is gone already. I'll have to clean the lemon juice out but that's easy compared to the awful odor of rancid oil.
I am not sure if you can prevent the nozzle from ever clogging, though I am trying the regular olive oil now.
I tried the spraying hot water method which was helpful, but didn't completely clear the nozzle. I have been using extra virgin olive oil.
The tool that did the trick is a DenTek Easy Brush for Extra Tight Spaces, if you happen to have one lying around...
The tip easily cleared the tiny nozzle opening without force. It was able to clean out the gunk without damaging the sprayer.
Cleaning (the manufacturer’s instructions):
We always recommend washing you MISTO® using directions included in the instructions booklet to keep the internal assembly clean and working properly. Usually MISTO® will need to be cleaned approximately every 6 to 8 weeks to keep it working smoothly.
Fill the MISTO® 1/2 full with hot tap water
Add one drop liquid detergent and shake to mix.
Pump 10-15 times
Spray for ten seconds
Allow the soapy water to remain in the sprayer for several hours or even overnight. This will allow it to break down any oil that has solidified in the sprayer.
Rinse, repeat the sequence above with fresh hot water.
To clear clogged misters or spray nozzles remove the spray part with uptake tube and submerge it in soapy, hot water and soak for 20 minutes. Then pump the soapy water through the tube until it sprays or mists as it should. Be sure to rinse thoroughly before use.
Although I never used the sprayer for oil. (I use mine for vinyl graphic application spray) When the nozzle becomes clogged I remove the nozzle by pulling it straight up and then I position the nozzle opening over the plastic tube and push down forcing the fluid backwards thru the nozzle. It clears it every time. I think it would work for you too. Just remove the oil and use hot water to flush the nozzle. It could be messy so hold it over your sink.
My sprayer never clogs. I put my dried herbs & peppercorns in a small cheese cloth bundle. No debris from the spices and aromatic oil with every spray. I too clean my unit with inexpensive alcohol such as rum or vodka, every 6 weeks. I stay away from water, for cleaning, it tends to spoil the oil over a short amount of time.
Some people report that releasing the pressure after use prevents this problem from occurring (although probably wouldn't fix it. I've not tried it yet. You can depressurize it after use by unscrewing the white screw-on top or by turning it upside down and spraying the last bit out.
Also, I read somewhere not to use thicker oils like Olive Oil. I've had much better luck using thinner oils like rapeseed (I think). Extra Virgin Olive Oils is much thicker than regular olive oil and really cloggs it up.
When the output becomes a stream instead of mist, the problem lies in the atomizer's hole, not the bottle or the tube. Spraying soapy water through the hole generally isn't powerful enough to dissolve oil that has become a glob. Very caustic dishwasher detergent may be powerful enough but I wouldn't fool with that. A more practical solution is to mechanically clean the hole with a fine needle. Try first poking into the hole to unclog it and then follow all the other instructions for spraying hot soapy water. Make sure not to enlarge the hole by poking too hard. A small hole is what atomizes the liquid. A large hole will automatically result in a stream, no matter how clean. All you're trying to do is to dislodge any solidified oil or goop.
I generally clear my clogged misters / spray nozzles by unscrewing the spray part from the bottle and then submerging the uptake tube in very hot (but certainly not boiling!) water and then pumping as long as it takes to clear the clog out and start spraying a mist / spray pattern again. The hot water should be enough to break up the clogs, and the pump action should force the clog out.
I just cleaned our Misto using a cheap liquor (i.e. rum... not sugary liquor like brandy or tequila). Put about an oz in the canister, re-assemble, and pump enough pressure to spray. It worked its way through the atomizer nozzle. Then, dump out the excess, refill with water and repeat to rinse out the alcohol. I also put a few drops in the tube-insert, and scraped around with a small tip to clean that piece.
The rum dissolves the oil faster than soap and rinses cleaner than any soap. I taught my wife this trick and she now precleans all our cookie sheets with a quick rum-rub. She laughs at how easy it is. It lifted off years of caked-on cookie gunk. It sounds crazy, but it works.
I empty my Misto and add 1/2 tsp of dishwasher detergent powder and fill half way with very hot water. Pressurize the Misto and empty the detergent solution. Then, rinse very thoroughly with several changes of hot water, then finally with two changes of good drinking water. The final rinse can be sprayed into your mouth to confirm the complete removal of all detergent. This has worked several times for me.
