How To Remove Solder Drips From Copper Pipe

There are many ways to solder copper pipe for plumbing, but no matter what technique you use, you’re likely to end up with some excess solder on your project. These drips look aesthetically unpleasing and can also be a nuisance when trying to fit the pipes into their fittings or connectors.

Thankfully, removing these drips is not difficult and only takes a few minutes. If you have the right tools, it is even easier than creating them in the first place. Read on to learn more about removing soldering drips from copper pipe and other projects.

How to remove solder drips from copper pipe

Sandpaper

The easiest way to remove solder drips from copper pipe is to use sandpaper. Begin by wrapping sandpaper around a wooden dowel or putty knife. Hold the copper pipe vertically against a flat surface and rub the sandpaper along the seam of the pipe. This will knock off the excess solder, leaving a clean seam with no solder drips.

Razor Blade

Another method for removing solder drips from copper pipe is to use a razor blade. Gently scrape the razor blade against the seam of the pipe. This will remove the excess solder, leaving a clean seam.

Soldering Iron

A third method for removing solder drips from copper pipe is to use a soldering iron. Apply a small amount of solder to the seam of the pipe. Once the solder is warm, use the tip of the soldering iron to remove the solder. This will leave a clean seam with no solder drips.

Solder suckers

A solder sucker is a type of vacuum that’s used to remove excess solder after soldering copper pipe. As the name suggests, the solder is sucked out of the seam without the need for scraping or sanding. Solder suckers come in different sizes, which determines the size of the copper pipe that can be used with them. They’re also available in cordless versions if you don’t have an electrical outlet nearby.

Conclusion

Soldering copper pipe can be tricky, but with the right tools and techniques, it’s fairly easy to manage. Removing the excess solder drips is one of the last steps in the process, and luckily, it’s also one of the easiest. We recommend sanding the seam with sandpaper or using a soldering iron to remove the excess solder. If you’re dealing with a large amount of drips, a solder sucker is the best way to remove them.
