Best Anti-Spatter Spray for Welding 2020 – Reviews & Top Picks
Last Updated: August 6, 2020
Welding can be messy, but you don’t want messy welds. In fact, we all want clean welds that look as pretty as they are functional. But spatter can make this difficult to achieve. Little beads of metal harden onto your finished pieces and force you to spend lots of time cleaning up if you want a beautifully finished weld.
Luckily, there is a solution to this problem. Anti-spatter sprays can be applied to your metal to stop the spatter from sticking, reducing your clean up time and improving the quality of your finished welds. There are many of these products on the market, but they don’t all perform as well as we’d hope. After testing as many as we could, the following eight sprays are some of our favorites. We’ve written reviews comparing them so that you can understand their differences without having to purchase and test them all.

The 8 Best Welding Anti-Spatter Sprays
1. CANTESCO Anti-Spatter Welding Spray – Best Overall
The AS-16-A Red heavy-duty anti-spatter from CANTESCO is one of the best formulas we’ve used. It was very effective at preventing spatter from sticking anywhere we applied it. This mixture is devoid of any silicone, which is important if you plan to paint the metal at any point. Though you may expect it to be oily and wet, the CANTESCO anti-spatter spray goes on dry and doesn’t make a mess. We’d recommend keeping it away from where your bead is going because it can definitely stop the weld from adhering properly if it’s applied directly to the joint you’re welding. This one isn’t the cheapest, but it’s also not the most expensive spray we tested. Overall, we think that it’s the best welding anti-spatter spray out there right now.
2. Weld-Aid Anti-Spatter Liquid – Best Value
We were looking for the best anti-spatter spray for welding for the money, and with the Weld-Aid Weld-Kleen heavy-duty anti-spatter liquid, we think we’ve found it. This spray is much lower-priced than many of the competing formulas, which is made even better by the fact that it’s a 20-ounce can, while most of the others we tested were only 16 ounces. Of course, that wouldn’t do much good if it wasn’t effective at reducing spatter. In our testing, anywhere we sprayed the Weld-Kleen, the spatter wouldn’t stick. Any of it that was visible after welding was easy to wipe off with a gloved finger. That said, it does contain some harsh chemicals that you shouldn’t breathe in. As long as you’re not putting your face too close to your work, this is a great spray that performs admirably for a very affordable price.
3. Lincoln Anti-Splatter Welding Spray – Premium Choice
Lincoln Electric is one of the biggest names in the welding industry, so it makes sense that they’d produce a great product for reducing spatter. This anti-spatter spray is a bit pricier than many of the other options available, but in our experience, it works like a charm every single time. Spatter couldn’t stick to anywhere that we had sprayed it, saving us tons of time in cleanup. The can is just 16 ounces, but luckily, it doesn’t take very much to work. A small spritz is all you need and your metal will be spatter-free when you finish your welds. Just be careful not to spray it where you’re running your bead. This stuff really works, so it can make it very difficult to get your bead to stick if you aren’t careful with the overspray.
4. Hot Max 23000 Anti-Spatter Spray
This anti-spatter spray from Hot Max is an excellent performing spray that’s just too expensive to earn our top recommendation. But it does work very well, which is why it’s fallen just short of our top three in the fourth position. It’s a silicone-free formula, so you’ll have no trouble painting your metal after you’re finished welding. Though it’s just 16 ounces, this can cost more than twice as much as some of the other sprays we tested. It’s hard to justify spending so much more when other formulas worked equally well. But if you’re in a pinch, you can count on the Hot Max 23000 anti-spatter spray to deliver a clean surface that’s free of spatter beads.
5. Hobart Welding Anti Spatter Spray
Hobart is another big name in welding, and they make some high-quality tools. Naturally, we expected their anti-spatter spray to perform admirably, and it didn’t let us down. There was only a little bit of spatter left behind when our welding was finished, but it all came off with a gentle wipe down. What’s great about this spray is the low price. It’s one of the cheaper sprays we tested. But it did make a bit of an odd smell when we welded with it applied. There aren’t any toxic chemicals involved, though, so it’s nothing to be concerned about. Compared to the best sprays we got to try, this one left just a little more spatter that we had to wipe off, which is why it didn’t make it into our top three.
6. Forney 37030 Welders Anti Spatter
We’ve had great luck with Forney products in the past, so we expected a repeat performance from the Forney 37030 Welders Anti-Spatter spray. It did perform pretty well. Only a few small beads of spatter were left behind after using this spray. Most of them came off with a light fingertip brushing, but a few beads needed a wire brush to remove. This is one of the more expensive sprays, so we hoped it would leave behind no spatter at all. But luckily, it doesn’t have a wet coating, instead, applying in a dry form. We did notice that it doesn’t seem to adhere to metal that’s already hot though, so you’ll want to spray this on your entire piece before you start welding. But don’t spray it where you’re applying your bead. It will prevent the bead from taking and you’ll end up needing to clean the spray off and start over.
7. CRC Welder’s Anti Spatter Spray Coating
This spray from CRC is water-based, so it’s easy to clean up any overspray. But we didn’t like how it applies. When you spray it, it foams up and expands, covering more area than you intended to spray. We like that there are no ozone-depleting chemicals in the formula. But it only works moderately well. We’d accept a few chemicals and fumes if it meant that this spray performed better. We had to take a wire brush to our metal after welding to remove all the spatter, even after applying this spray. Since the spray is so thick, it stays on your material after welding and doesn’t evaporate like the other sprays. It’s easy to clean, but it’s also easy to make a mess with it.
8. Weld-Aid Nozzle-Kleen Anti-Spatter Liquid
This anti-spatter spray is meant to spray on the tip of your welder to prevent spatter from accumulating and blocking the tip. It’s supposed to also stop spatter from sticking to your metals as well, but in our experience, it was one of the less-effective sprays at managing this. In fact, we couldn’t tell much difference between welding with and without this product on our finished metal. That said, our tips didn’t accumulate any spatter, but this isn’t usually a major problem anyway. What’s worst about this spray is the hazardous chemicals it contains. You don’t want to breathe them in, so using this spray in a small workshop isn’t a great idea. Overall, we’d suggest staying away from this spray and opting for one of the formulas that earned a higher position on our list.
If you’re having copious amounts of spatter left over after performing your welds, then an anti-spatter spray is an easy way to drastically improve the quality of your welds and decrease the amount of time you spend cleaning them up. Our reviews compared eight of the best anti-spatter sprays on the market, but only three of them earned our top recommendations. The CANTESCO heavy-duty solvent-based anti-spatter spray was our favorite overall. Its silicone-free formula goes on dry instead of oily and wet, and it was very effective at reducing spatter, stopping nearly all of the spatter from sticking to our metals.
For the best value, we like the low price and larger 20-ounce can of the Weld-Aid Weld-Kleen heavy-duty anti-spatter liquid. It’s also very effective at stopping spatter, and it reduced our clean up time drastically. Finally, for the best performance at a premium price, the Lincoln Electric anti-spatter spray is a very effective product. It doesn’t take much to work, but it works every time. We feel confident recommending any of these three sprays, and we’re sure they’ll help clean up your welds immediately.
