On the right, you see the sponge from my soldering iron stand. On the left, a replacement bought this week from Squires.
What a poor, tired thing the old sponge was. At about a third the thickness and full of solder it really wasn’t doing its job.
Proper modellers clean the tip of their iron every time they make a joint. I probably do this every third or fourth joint. A clean iron makes better joins, it’s that simple. Back in the old days people would file excess solder and that weird black muck off the end of the iron. This also removes the plating and dramatically shortens the life of the bit. File too hard and it dramatically reduces the length and shape of the bit as well.
The old sponge has been in use for at least five years. I wonder if the new one will last as long ?
