Cleaning a Dirty Soldering Iron

Updated: 2 days ago

If you're just starting out with stained glass, you'll soon come to understand the importance of maintaining a clean soldering iron tip. When you begin working with stained glass soldering irons, it's important to learn the correct ways to clean your iron. Some people, eager to dive right in, may encounter a roadblock when they realize that their solder won't adhere to their iron's tip or their foiled copper glass pieces. Assuming we all have a general understanding of the purpose of a soldering iron, let's move on to discussing how to clean it effectively.

What Causes My Iron To Get Dirty?

Oxidation is the culprit! The oxidation is caused when the iron plating on the tip transforms into iron oxide.

This is a natural part of the metals used in soldering. While oxidation can happen at room temperature, it takes place at a much slower pace. However, when you start soldering, the heat greatly accelerates this process, thus causing build up between your iron tip and solder. This will cause problems in your solder adhering to your iron tip and copper foil.

Cleaning Options:

Everyone has their own preferences, so it's natural for opinions to vary. Some may not agree with certain options I propose, while others may fully support them. Ultimately, it's up to you to decide what works best for you based on your own experiences and trials.

1. Using a Damp Sponge:

It's possible that you were instructed to clean your soldering iron tip with a damp sponge, a technique often taught in stained glass crafting. Despite this, I've discovered that this method can cause more problems in the long run. The minerals and debris in the water and sponge can contribute to buildup, while exposing the iron plating to air and water can lead to rust. Using a wet sponge can also expose the tip to thermal shock from a sudden temperature decrease. To avoid these issues, make sure to re-tin the tip immediately after cleaning. I have used this method in the past and it is not one I prefer.

2. Use a Steel Brush, Sandpaper, or a File:

Uh, NO!! Using these methods to clean your soldering iron tip is a big no-no if you want to avoid damaging it.

It's surprising that some people actually recommend it. Avoid using these items to clean your iron tip to prevent

problems and the need for frequent tip replacements.

3. Use a Brass Sponge:

Keep your soldering iron tip in top condition by using a brass sponge. Brass sponges are superior to traditional sponges and won't cause any damage to your iron tip. They clean without water - simply insert the tip into the coils. This method is a great alternative to using a wet sponge as it helps prevent rust and extends the life of your iron tip. Don't forget to remove the brass sponge from the base periodically to clear out any remaining solder bits.

Re-Tin Your Iron Tip Immediately!:

It's important to remember that tinning the tips means applying a layer of solder to cover the tip of the iron. This simple step can prevent the tip from disintegrating quickly if it develops a hole or crack.

Tinning also helps the solder melt and flow smoothly, making your soldering job easier. Don't forget to re-tin your soldering iron tip before, during, and after each soldering session.

To re-tin your soldering iron tip, follow these simple steps:

· Heat the iron to the correct temperature

· Clean the tip with a damp sponge or brass sponge (your preference)

· Apply solder evenly to the tip

· Allow the solder to melt and coat the entire tip

· Wipe off any excess solder

· Repeat this process regularly to keep your tip working well

My Iron Is Still Dirty After Cleaning and Solder Does Not Stick!

If you find that the solder won't adhere to the tip of your iron even after cleaning, it's likely that the tip is still oxidized.

There could be a few reasons for this. One possibility is that you forgot to apply a protective layer of solder after cleaning. Personally, I make it a habit to wipe the tip and apply fresh solder after every minute of soldering and before placing it back in the holder. Another reason could be that you set the heat too high. If none of these apply, an easy fix for this is using a Sal Ammoniac block. Occasionally, people raise concerns about using Sal Ammoniac to clean soldering iron tips. However, as someone who is involved in stained glass crafting, I can confidently say that I use this product myself. In my personal experience, I have found that Sal Ammoniac effectively removes stubborn oxidation and is completely safe to use on copper foiled pieces.

Use of a Sal Ammoniac block

Safety First: Remember to wear a mask and/or use a fume trap while soldering to protect yourself from any fumes. It's possible that some fumes and/or smoke may be produced when using a hot iron tip on the tinning block. Make sure to work in a well-ventilated area for your safety. Refrain from drinking liquids and smoking while handling this product, and don't forget to wash your hands right after use.

Sal Ammoniac, also called a tinning block, is a fast-acting cleaner for the residue that builds up on your soldering iron tip. Occasional to regular use of a tinning block can help prolong the life of your soldering iron tip. A medium-sized block can be a long-lasting investment for most glass enthusiasts!

How to Use:

Make sure your soldering iron is fully heated up.
Ensure the block is stable and won't move as you slide your iron tip across it.
Place the hot soldering iron tip on the block until it starts to smoke, then move it back and forth slowly. Initially, the block will turn black from the contaminants released by the soldering iron tip.
With repeated use, you'll see grooves developing on the block. Utilize these grooves to help guide the iron tip along the rounded edges of your iron’s tip.
By moving the bit back and forth on the block, you'll see it getting cleaner. Afterward, you can apply a small amount of solder and turn the tip around to check for any remaining black spots.
Repeat these steps until the tip of your iron is shiny and has a small amount of solder on it.
