	extra flux / flux pen	Extra Flux can be helpful when soldering. Flux makes the solder flow better into the cavities and generally helps get a good solder joint.
	isopropyl alcohol / PCB cleaner	IPA or PCB Cleaner is super cool to make the PCB look good after you are done soldering.
	brass sponge	With a brass sponge you can clean the tip of the soldering iron. A brass sponge is a small investement but surely a good one! It makes soldering that much easier when you can work with a clean soldering iron tip!
