This is what I have been using to remove flux after completing a board right before I enclose it. I get it from a local electronics shop. It works pretty well, but I think it's kind of pricey. This can is almost empty so I wanted to see if anyone had any suggestions of what works for them.

How about you back to the future, and use... yes, you guessed it... a Flux Capacitor! :D

Just kidding... what you show is the only stuff I know of.
 
rubbing alcohol works, but you should get the highest percentage isopropyl alcohol you can find to do it. you can wet it down with the alcohol and use compressed air to make it dry quicker.

+1 for isopropyl alcohol. I apply it with a qtip. Usually works pretty well.

I used to use this method. But, when I switched from a generic flux in a can to Kester 186, isopropyl alcohol no longer worked and in fact made things much stickier. I haven't found a method for cleaning this, but also don't care much because it's non-conductive and makes for a far superior soldering experience over the traditional flux. If anyone has a cleaning solution for this I'll try it. Either of you guys try those spray-on solvents with this flux?
 
I highly recommend it as it's MUCH easier to use in that form. After I got it an RF EE friend mentioned it's what he and all of his colleagues have it at their desks.

I almost got one of those instead. I worried that the tip wouldn't be able to get flux onto areas that weren't a flat plane, and also that the tip would wear out before I used all the flux. Have you experienced either of these?

I've ordered the MG Chemicals flux remover and the Kester 186 flux. I'll let you know how it goes.

Just as a heads up, wear gloves. I wear rubber gloves from harbor frieght and if i do more than four boards that stuff will destroy the glove. Works great and for that reasoni dont want it touching my skin
 
The flux remover came in, but the flux isn't here yet. The MG Chemicals works better than the Techspray on the flux that is in the kester leaded solder I am using, but it does have more fumes and takes longer to dry.
 
I used the kester liquid flux today and cleaned up with the MG chemicals heavy duty flux remover. I thought it did a good job of removing the flux residue.
