This glass oil sprayer is valued for its low price and handy use in the kitchen, especially for air fryer cooking and other light spraying tasks. The black version is the one that consistently works with the clipped coupon, and the final price has landed around $5 to $9 after discounts and tax. It has a glass bottle and a solid feel, but cleaning can be a hassle, and the spray mechanism can be awkward at first or even squirt instead of misting well. The glass body also makes it vulnerable if dropped, so it is a practical pick when the coupon applies and careful handling is not an issue.

  • Switching to the black model can enable a clipped coupon and lower the out-the-door price.

  • The glass bottle design can feel better and may be preferable to plastic sprayers.

  • The sprayer can work well for air-fryer cooking by spraying oil instead of brushing.

  • A vinegar-then-dishwasher cleaning routine can keep the sprayer usable with minimal effort.

  • The sprayer can be difficult to clean, and some people stop using it after multiple attempts.

  • Glass versions can be fragile if dropped, and heat near the stove may also be a concern.

  • Early operation can cause the thumb latch to misfire, spraying EVOO onto unintended kitchen surfaces.

  • The sprayer may not spray consistently and can instead squirt oil like a poor water gun.

Just a heads up, these are a pain in the ass to clean. We went through two before realizing that we don't really need to "spray" our oil...using a brush works just fine.
I spray my oil for almost everything i put in the air fryer, works better than brush IMO

What makes this one special compared to the various $8-9 ones on sale on Amazon
supposed to be a "better" one. This one has almost 5 stars with 48K review for less than $8, less than $7 if buying a pair. I would buy both and keep the better one:

How often does it need cleaning. I want one, but that's the main issue, is it worth the hassle. Thanks!

the question about things like this is does it actually spray well? I bought a different one before and it doesn't spray so much as squirt oil like a poor water gun Frown

I just put some vinegar in mine and spray it until the vinegars gone, then spray water to rinse the vinegar, then put in the dish washer. Seems to clean it fine and is not much work at all

100% right, we threw these away after realizing how hard it is to clean. Simple good old school glass bottle is all we needed.

If you don't need to spray, then why not this Oil & Vinegar Plastic Squeeze Bottle?
