EWK 22 oz 110 psi Refillable Aluminum Aerosol Spray Can for Brake, Machine & Engine Cleaning

I just used this today to remove a huge vinyl sticker from the hood of a car. I ended up having to apply some adhesive remover to the sticker. I was able to change out different chemicals fairly easily. You can't fully get it all out, you may have a little residue in the tube and spray head. You may need to purge them for 100% purity. I used the spray feature. I only had about 90 psi compressor pressure. It worked pretty decent. More pressure would help, like 120psi or more. Not sure what the limit is. The only issue I had was when using a very thin chemical. When I released the trigger, the material kept spraying for about 5 seconds. Showed it to my neighbor, he was like, I need one of those. The canister is made of nice formed aluminum with a heavy threaded collar. The spray head is heavy plastic and very good quality. I bought the extra spray tips but have not used them yet. So glad I had bought this 2 weeks ago. Very handy for multiple uses

Filled with ATF & Acetone to make a penetrating fluid. Worked fine for 15 minutes, then stopped spraying correctly. I am well aware Acetone eats plastics, but the plastics were not melted or anything, nor would I expect it to be for a sprayer like this. It sprayed somewhat thru the "flip down" mode, but when flipped up (straw mode), nothing happened. The o-ring in the flip-up sprayer fell out too. Piece of chinese junk. Have since purchased a Sure-shot (not big can style) brand of this style and it works perfect.

So you should know, usage as an air duster was not its primary purpose when designed. For that purpose its okay, not high pressure, but can work for some light dusting. As for its intended purpose, its awesome. I load it with cleaners and use it when detailing my cars. Seems to make the cleaners more active as it leaves in a foamed state. Nothing ridiculous, its similar to how a can of aerosolised glass cleaner comes out. Holds pressure with no issue for a week. Tops out around 90PSI with a safety valve, so you can't blow it up as long as that valve functions. Robust construction, feels solid. Can be filled by anything with a tire chuck. Bike pump, air compressor, car compressor, etc. The extendable precision nozzle is great for getting a small amount of cleaner into a tight space. Strongly recommend if you have a great cleaner like simple green, but you wish it came in a pressurized can instead of just a spray bottle. Will work with anything not caustic, do not put in bleach or acetate.

I have two of the earlier version of these - press button not trigger. They do what they're designed for - spray low viscosity (thin) liquids. Negative criticisms miss the point. Some Notes.. 1. This is not an air duster and not meant to be. Real air dusters use a chemical that turns to liquid at pressure - look it up - and will blast out a gas (it's NOT air!!) for several minutes. Try it with this and you'll get a few seconds only. Don't buy it if you want a gas duster and don't whine if you do and are disappointed 2. Don't over-pressurise it. It says 90 to 110psi and is fine at that. There's a pressure release valve so it should not be possible to exceed this. If you defeat the valve and use higher pressures expect it to explode and possibly cause serious injury. Don't do it!! 3. It's aluminium. Don't use corrosive chemicals because many will eat into the aluminium, weaken the can and cause it to rupture. Stick to solvents and lubricants only. Now comments on how well it works when used for its intended purpose.. Generally it does what it's supposed to do and not only does it save a fortune in aerosol cans but it also allows you to spray custom mixes...1:1 WD40 and Fluid Film say.....but there are some niggles with it. 1. No filter on the pickup tube - so if you get any contaminants in there it will clog the nozzle. This is a real pain. Either use very clean fluids or pour them in through a fine mesh filter. Or buy a fine mesh fuel filter and stick it on the end of the pickup tube ..see photo. This works if used upright but if you invert the can it switches to a different inlet and will bypass the filter 2. The plastic around the base of the steel spray tube eventually crack and it leaks. This is is a killer and a major complaint. I have two of these and both failed the same way. Because it's so useful I fixed it by pulling out the steel nozzle to allow the crack to close, wrapping a fine stainless steel mesh around the plastic and using a hot iron (plastic welder) to embed the mesh into the plastic and hold the crack closed and reinserted the steel nozzle. Been OK for over a year now but you shouldn't have to do this!!! Bad design 3. Loses pressure as it empties. But his is really a minor thing and hard to design out if you're a manufacturer. Cause - as you're using compressed air not a volatile propellant as in a normal spray can then as the can empties the pressure will drop. The more liquid you put in the less room for air and the more the pressure drops. Best to fill say 50% and pressure will then only drop 50% from full to empty....or just top up pressure occasionally from an air compressor. Overall very useful but some flaws. Worth buying despite the somewhat high selling price

I go through a lot of brake cleaner, so this tool made sense to me. I bought a 5-gallon container of brake clean and started using the refillable spray can. I filled the spray can halfway with brake clean and added 90PSI of compressed air. The spray can instantly clogged. I cleaned it out and was underwhelmed with the dual nozzle spray/straw it came with so I used one of the nozzles from Spray Can with Nozzles Kit version I bought. The Spray Can with Nozzles Kit version was also delayed a few weeks. The head of the spray can is plastic and I'm afraid I'm going to snap it one day. It feels a little cheap. Same goes for the dual nozzle spray/straw it came with. As mentioned before, I prefer to use one of the simple beefy nozzles from the nozzle kit version I bought. When the spray can clogs, I remove the nozzle and shoot compressed air in the opposite direction to clear it up. I put that one on me as debris can be introduced to the bottle when I refill. The can bulges a little when filled to 90PSI. It's a bit scary at first but it's fine. Other annoying issues is the trigger sticks sometimes when I let go of the trigger causing the spray can to continue to spray. There is a trick to get it to only spray when you want it. You can't squeeze the trigger all the way if you want it to stop right away. I'm not sure if this is on purpose. All-In-All, the refillable spray can works but it's a bit clunky.

Really appreciate how well this works. Much cheaper to buy bulk fluids and add them into this container. I make my own diy cleaner for intake valves and this works amazing for spraying it on.

I have veen looking for a profuct like this for a while, and this one really exceeded my expectations in terms of quality and functionality. Delivery took some time, but I am very happy overall. Highly recommended to anyone on the market for a portable spray cans

We received this sprayer on a Monday , filled it with brake clean , added air , worked fine , put it away and then one of my workers went to use it on Wednesday and nothing sprayed out. He said the brake clean ate the seals and it will not hold pressure. Amazon will refund my money if I drop it off at a UPS location , well , its not feasible for me to take an hour off work to drive 50 kms to a UPS location. Not every town has a UPS!!!!!!

Great product until you need replacement parts

Very well built and works perfectly
