Many people swear by plain rosin flux, me included.
It's pretty inert so can be left on the boards.
To apply it to a board you can dissolve the rosin in some ethanol or
IPA rubbing alcohol. Put it in a bottle with a dropper cap or brush
cap.
For tinning wires and stuff I just hold the wire against a chunk of
rosin and heat with the iron.
Since rosin comes pretty much straight from the trees it is dirt cheap.
