I know it's a bit off-topic, but I can't find any reply to my case.
I recently used a steel stencil (designed with KiCad) to dispense solder paste on several (small) panels and assembled them, but I now want to clean it before storing for a future use.
Can you recommend a way to clean it properly ? There are some solder paste residues inside the holes thickness, and cleaning them individually with a toothpick or other sounds really tedious !
Any hint please ?
