An ink eraser is handy for clean pcb traces

If your system involves lethal voltages/life critical/flamable elements - you probably shouldn't need to ask.

P.S. I won't start a whole new thread for this but also buy desoldering braid. It comes in very handy as well.

   

I prefer a de-solder pump. They are really quick and easy, and can clear large blobs almost immediately. And they are re-usable, so you do not have to keep buying more!

Not useful for surface mount, though. Can't get a good seal to the edge of an IC and with some huge thing jumping around next to fragile pins you're going to break something.

Desoldering braid is definitely a must-have. When you need it, you NEED it.

That's probably true. If you do a lot of soldering, you should have some braid.

And I do have some braid. But I've never used it. Never needed it. I do, on the other hand, use my "solder sucker" bulb pretty much every time I solder. It's a very handy device. I would never solder without it.

I might mention, too, that I never have attempted to solder a surface mount device. Probably never will. As noted, I suspect braid would be much better for that.

Right....I have never used desoldering braid on through hole parts either. I do grab the soldapult for those. It's not in the NEED zone, but most times is easier than whacking the PCB on the bench while melting the solder.

One note about the water-washable flux:

1) You *MUST* wash it off -- it's a lot more corrosive than the Rosin or No-Clean types
2) You need hot water to fully get it off. I use a cheapo Harbor Freight ultrasonic cleaner with built-in heat and it works really well for the purpose.

Personally, I prefer it because the higher activity makes better joints.
