The type of flux you need is dependent on the job it is for. If you need it for a plumbing job, you will need a more aggressive flux than, say, for electronics. I suggest you go to a shop that caters for your type of needs and buy some.

Lemon juice makes a fair replacement for light soldering jobs. Just squeeze a little juice from a lemon and use a brush or Q-tips ⇦ this on eBay or Amazon [affil links] to apply it. The joint should look shiny when finished, if not it may not be a good connection. Try again. I hope this helps.
