MG Chemicals - 403A-285G 403A 134A Super Cold Spray, 285g (10 oz) Aerosol Can

Fast-Acting Freeze Spray for Electronics and More This MG Chemicals Super Cold Spray turned out to be one of those “better to have it and not need it than need it and not have it” tools. I originally picked it up for electronics work, and it’s been great for quickly cooling down overheating components and chasing intermittent faults on boards. The nozzle delivers a sharp, directed burst of cold that works instantly, which makes it very practical for pinpointing heat-related issues. Beyond electronics, I’ve also found it handy around the house—like freeing up sticky gum or wax, or cooling down surfaces during small repair projects. The can has a good size (10 oz) and the spray force feels strong without being wasteful. I also appreciate that it uses 134A refrigerant, which doesn’t leave messy residues. A couple of things to note: the can gets cold quickly, so gloves help if you’re doing multiple sprays in a row. And since it’s an aerosol, it’s best used in ventilated spaces. Bottom line: A reliable, versatile freeze spray that works fast, lasts a long time, and is a great addition to both an electronics bench and a general DIY toolkit.

This stuff works great for skin tag removal. Use something to limit the space where it is sprayed, or you will end up like other 1 star reviewers. All of those people should've given it a 5 star for it's effectiveness. We are using it for something it was not designed for, but it works great with proper care. I personally use a larger straw that the red applicator goes into and I hold the straw very firm, hard and close to the skin so the 134 coolant doesn't spread to other areas of the skin. I only pull the trigger a couple, or few times to get enough 134 fluid on the skin tag. It turns red with in hours, black within days and skin is cleared up where I can't even tell I had one after about 2 months. I hope this helps.

Grabbed this mainly for chasing heat related issues on circuit boards and it works exactly how you want it to. The spray is focused and hits fast so you can zero in on a specific component without freezing everything around it. I don't have to reach for it super often but when I do it earns its spot on my desk every time.

Back when I was young I figured out to use bubble gum freeze spray and cheap clear bic pen. It worked but took a few times to kill warts. My kid had a wart on his knee so I tried Zep freeze spray first and it did a terrible job. After researching I found this spray. Stuff works phenomenally. I couldn’t find a bic pen so I modified a pen to work. You hold it tight to the area you want to freeze. The small hole on the side is key. It allows when you spray to release pressure. It will form a small all amount of liquid that bubbles in the end of the tube on the skin. It only takes a small amount so be careful. Short little bursts. One application and his wart was frozen solid. I’ll update if we have any issues.

I have had my warts treated 5 times. The one on my left hand is on the knuckle. It started as 1 wart. Then I had it treated. (Salicylic acid treatment and liquid nitrogen/cryogenic treatment). It came back as a huge cluster of warts that covered the bottom half of my knuckle. The other is on my right had on my middle finger. So when I rested my head on my clasped hands, my right hand gave my left knuckle the wart virus. My right hand has had cryogenic treatment 3 times. Every time it comes back. I was unwilling to pay the medical bill of $189 again. (This is after insurance). I started researching different treatments. Duct tape did nothing for me. Herbs did nothing. Burning it off didn't work. I did not want to have it cut out of me. So I researched the cryogenic treatment since it's had some success in the past. I researched the medical version of the liquid nitrogen spray guns. Those were $500-700. I tried to get a used one but auction websites rarely get them. So I started looking for liquid nitrogen. Not the easiest thing to get your hands on. Then I came across this. I read all the comments and other website forums. I followed the instructions and sprayed it on a Q-tip first and then pressed it into my wart. I held it for 10-12 seconds to reach at least 90 seconds of freeze time. When the Dr's did it, they only froze it for 60 seconds. It stings and the larger the area you have to freeze, the more it stings. It will sting for a long time afterwards. Some of my warts were small, so I only had to work a small area. Three area's were larger, about the diameter of a #2 pencil eraser. So I worked to accurately freeze them. It took me only 3 times to really get the hang of it. I am on my second freeze session. The first one was 2 months ago and it killed all the warts I correctly froze. Instead of a massive cluster of 17 warts on my knuckle, I'm down to 6. I'm anticipating 1 more freeze session. But I'm waiting 2 months between each time for adequate freezing. In my experience thus far, freeze the warts had given the best results.

Mine was used before it arrived. The straw was missing and there was no safety tab on the top. Good luck finding a replacement straw! If it wasn’t for this and the awkwardness using it, I would have given it five stars. I ordered some red straws that looked like those used for WD-40. The outside diameter was .085 inch, but these were too small. I tried holding the straw in, but spray came out around the straw hitting my fingers. That’s not an option. I used Q-Tips and that worked, but it wasn’t perfect either. The spray bounced off the Q-Tip onto my fingers. It wasn’t as bad as before, but it was still awkward. When I placed the Q-Tip on my skin, liquid in the tip sizzled as it boiled away coming up to room temperature. It stings a little, but it works as well as the cold spray my dermatologist uses.

I had a purplish 'lump' that showed up on my head at the edge of my hairline, I had a dermatologist check it out. He said it was nothing but a tissue mass and presented no health issues. He went ahead and froze that thing off, it was just a little smaller than a quarter and protruded maybe 1/4 inch? Anyway yeah it had to go, his freezing worked great except he missed a thin edge of it and a few months later it was coming back. I bought this and decided to give it a go myself, this stuff worked fantastic and I made sure to get all of it and so far fantastic results (couple months or so have gone by now). WARNING!!!! Let me give you some very good advice, I underestimated how much dmg this can do and how quickly it does it. I just wanted to spray the 'growth' itself so cut a hole in something and put it over it but didn't put much effort into that and I was doing it myself, results was a half dollar size freeze burn. Luckily it did not do enough damage to scar. You really, really should get someone (someone SENSIBLE) to help you with this and devise something with a hole to help you target only area you want or you can try like some say with Qtips, they actually work decent but for me the affected area was much larger than a skin tag so I sprayed directly. Anyway, just respect how much damage extreme cold can do to your flesh and you should be fine. I would also suggest that you always, always ask your doctor first before you use it on anything.

Stuff works. I got rid of two stubborn warts that I'd had for years. Using the attached straw, I sprayed product in a plastic cup. Careful! This stuff can be extremely dangerous! Do not let kids play with it and spray away from your body/face. Quickly, I soaked up the liquid with a Q-Tip and applied to the wart for about 30 seconds. I did that three times in a row (total 90 seconds). The wart will look white then turn pink. I repeated the process every other day two more times (total of 3 sessions). For the larger wart on my knee, a filed off the top layer of the wart so that it was a bit raw before beginning. After treatment, a blister formed on my knuckle wart. A week later the blister healed and there was healthy skin underneath. My knee's wart turned black (I'm Caucasian). After a week, I peeled off the black skin and there was healthy skin underneath. I'm so thrilled that this works. Talk about a money saver. The first time you try this, I recommend having a partner help you, as you'll probably be a little nervous. My husband sprayed the spray and swabbed the Qtip, then handed it to me so I could apply it to my own wart. This worked well. BTW, this treatment is not pain free. It does sting both during treatment and for a few hours after. I suggest doing it right before bed, so you can fall asleep afterward. But it's not that bad. I'm by no means tough, and I can handle it.

I liked the fact that it worked well without holding it upside down, like butane, etc and it has a nice trigger system to use as I had to design my own and to control how much came out, with this one, using very light pressure on the trigger, however, even at a very low trigger force, it can spit liquid, no doubt because I had cut my straw in 1/2 for better up-close work & control. To help keep it off your healthy skin around it, I found holding something with a small hole that fits as close as possible around the target area helped lots but only in short fast bursts as the liquid can still come up and over the edge running down healthy skin. It only turns it red, the target area you keep shooting small bursts at with a second or 2 break if it turns white as is frozen and can't freeze anymore until it warms up and keep hitting it with small blasts to keep it frozen for up to 1/2 to 1 minute. It will take time as my entire area that got liquid on is still red but you can tell after 5 days or so the target area is being affected. It will in time start to die to dry out, turn dark and may fall off in pieces as that is how it worked when I used Butane, pretty much as cold, never thought it worked until I saw it turn dark a week later and it came off in pieces (3) and now totally gone with no scare. It appears this will do the same but better with much easier control. I even cut my straw in 1/2 for closer work and control leaving me an extra if I were to lose it. Love using this. Remember the liquid as if holding upward at an angle it can drip onto your fingers or hand.

I searched other apps for purchase through, but they're showing low prices also. They're not authentic dealers. Thanks to Amazon and the seller.

Working well
