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.

Common Questions (5)

  • The coupon appears to work on the black version, but not on the gray or white versions. Switching the selection to black and clipping the on-page coupon is what enabled the discounted price for several shoppers.

  • The glass bottle feels high quality to some buyers, but the glass can break if dropped and the unit may be damaged by heat near the stove. That makes it better suited for careful countertop use than rough handling.

  • Prices reported ranged from about $5.33 shipped to about $8.55 after tax, depending on the listing price and coupon combination. The black version was the one that consistently triggered the discount.

  • Yes, it can be a pain to clean, and some users gave up on it after repeated use. A workable cleaning method is to spray vinegar through it, rinse with water, then run it through the dishwasher.

  • It can spray well for air-fryer cooking and general oil use, but it may also behave more like a squirt bottle if the mechanism is finicky. The first few uses can trigger the thumb latch and spray oil onto nearby surfaces until you get used to it.

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?
