After I finish soldering, there are little splatters of solder stuck all over my panel. How do I clean these up?
Doesn’t it look just terrible! You wonder if it will ever get clean. But don’t worry, it really isn’t as bad as it looks.
Any of the splatters that are not connected to a solder seam can usually be removed with your fingernail (after the solder has cooled!) or a soft stick, like a craft stick (top left). Be careful not to use anything sharp that could scratch the glass. This includes most steel wool (except 0000). Most scrubbing pads for dishes will work, but you should try them on a piece of scrap glass. You don’t want to scratch your project now!
Any splatters that are connected to a solder seam will need to be refluxed and melted off. Trying to lift it off with your soldering iron will generally leave a peak, so you’ll have to melt it into the solder seam at that area. If the splatter is too large to melt into the seam, you’ll have to melt the seam and remove the excess by quickly pulling it off to the side with your soldering ion.
You may notice that you get more splattering when soldering the second side of your project. That’s because the flux gets trapped between pieces of glass. (On the first side that you solder, the excess flux just slips through to the other side.) When the trapped flux gets hot enough to boil, it bubbles up through the solder, sometimes leaving little tiny splatters all over your project.
