Soldering copper pipe is a great way to finish your plumbing project and make it look professional. However, using heat to solder copper pipe can be tricky. If you don’t know how to solder copper properly or you aren’t using the right tools, you might struggle with getting your pipes soldered and leak-free. Failing to remove the excess solder from your copper pipes can be frustrating because of its appearance and how much time it takes to get rid of it.
Thankfully, there are many ways to remove excess solder from your pipes so they look professional again. If you’re struggling with soldering copper pipe, this article will help you understand the best way to remove any excess solder and keep leaks at bay in future projects. We’ll go through some tips on how to remove solder from copper pipe along with different methods for doing so at home. Let’s get started!
Tips for Removing Solder From Copper Pipes
When you’re soldering pipes, there are a few things you can do to get rid of excess solder at the end of the project. First, you should always prep your pipes. Before you solder, make sure your copper pipes are clean and free of any dirt or grime. Using a cloth that is slightly wet, wipe down your copper pipes so you can solder them more effectively. Also, make sure you have your pipes bent at the correct angle. Next, you’ll want to use the right amount of solder. When soldering copper pipes, make sure you use too little solder. Doing so will make it much more difficult to clean up any excess solder because it’s harder to get a wet sponge to all parts of the pipe. It’s better to use too much solder than too little because you can get a sponge or steel wool and wipe it off to remove it.
Heat and Time
The amount of time your pipes are in the flame will directly influence how much solder is left behind on the copper pipe. The longer your copper pipes are in the heat, the more solder will be left on them. While this is not an issue for a new project, it becomes a problem if you don’t clean up the excess solder. You’ll want to get the copper pipes out of the flame as soon as the solder flows. Soldering copper pipe is all about controlling the heat, so you can prevent it from getting too hot. There are times when you might want to intentionally get the copper pipes hotter than others. For example, if you’re soldering a copper pipe inside a wall, you might want to get the copper pipes nice and hot because the extra heat will help the solder flow more easily through the copper and into the wall.
Solder Wick
If you’ve tried everything and you still can’t get the excess solder off your copper pipes, then it’s time to break out the solder wick. Solder wick is a very useful tool that helps you get the last bit of solder off your copper pipes. It’s a copper wire that is impregnated with flux and has been wound around a spool. You simply feed it into the copper pipe and let it suck up the excess solder. You can use it for a variety of projects as well. Since solder wick will be in contact with your copper pipes, it’s important to clean your copper pipes before you use it. You don’t want the solder wick to get stuck, so getting your copper pipes clean is the first step. You can use a wire brush to get the excess solder off and then wipe everything down with a cloth. Solder wick can be messy, so make sure you work on a surface you don’t mind getting dirty and cover your hands with gloves.
Wet Sanding
If you’ve tried everything and the solder wick isn’t cutting it, you can try wet sanding your copper pipes. This is a more aggressive clean that will get every last bit of solder off your pipes. You’ll want to make sure your copper pipes are dry before you start sanding because water and copper pipes don’t mix. If you get water on your copper pipes, you’ll end up with a nasty, electrical short. Before you begin sanding, make sure you’re using the right grit. You’ll want to start with a medium grit and work your way down to a fine grit. Some sanding pads even have solder already mixed in them, so you can sand at once. If you’re cleaning your copper pipes with sandpaper, you’ll want to make sure you’re wearing gloves and work in a ventilated space.
Wire Bristle Brushes
You can also use a wire bristled brush to get the excess solder off your copper pipes. The wire bristles get into the crevices of the copper pipe and help you clean them up. You’ll want a copper brush so you can get the grit and grime off your pipes. If you have a nylon brush, you’ll be scrubbing away at the solder and not getting the pipes as clean. You may need a few different wire bristled brushes to get all the crevices of the copper pipes. Before you begin brushing, make sure you’ve cleaned your copper pipes off first. You want to be as gentle as possible with the wire bristles, so make sure they’re clean and you’re brushing gently.
Chemical Cleaners
You can also use chemical cleaners to get the excess solder off your copper pipes. This is a more extreme way to clean your copper pipes and should be used as a last resort. Make sure you read the instructions on the label of your chemical cleaner because each one works a little differently. You can also use a chemical cleaner if your copper pipes are wet. If you’re cleaning wet copper pipes, you’ll need a chemical cleaner that is made for that. When cleaning your copper pipes with a chemical cleaner, you’ll want to follow a few tips that will help you get the best results. First, make sure you’re cleaning the copper pipes in a well-ventilated area. You don’t want to be inhaling the fumes from the chemical cleaner for too long. Secondly, be careful not to get the chemical cleaner on anything but your copper pipes.
