I'll have to wait another two days for the last two parts to come in, but I'd like to start soldering now. I'm using 63/37 solder (RA flux, 2.2% flux), and I was wondering how long after soldering can I wait without cleaning the board before damage occurs? I'm pretty sure the "A" in "RA flux" means "activated". I think it's corrosive... Would it be safe to solder, wait for two days or even one whole week without cleaning, complete soldering, and then finally clean the flux off the board with alcohol?

Probably a year or 2 

 
Rosin fluxes are corrosive, but not very much.
