Lead free solder is just fine, provided that your iron gets hot enough to melt it. Newer soldering irons do operate at a higher temperature; if you are using an older iron with lead free, it can sometimes be a little challenging. 

(And, if your solder is narrow gauge, flexible, and is sold as solder at radio shack, it probably has a reasonable flux core, whether or not it’s rosin based.)
