I use a couple of cheap small wood carving chisels that I got in a set from Harbor Freight. Both are straight chisels, one is 1/4" wide the other 3/16". I use these to get the large blobs and excess solder along the ribs and barrels. I use a small mallet to drive them, BUT, be careful, it is easy to hold them at too steep an angle start to cut into the steel! Then you have a lot more work removing/sanding out the divots (I have never done done this, but I have heard this can happen - yeah, right!).

Almost forgot to mention that I also have a 3/16" Allen wrench that I have ground the short leg into a small scraper. After using the chisels, I use this scraper. It really peals out the solder material without much worry about gouging the steel.

After that, I have a piece of 1/4 aluminum plate 1.5" x 4.5" (nothing magic about the dimensions, was a scrap piece I had laying about), that I cut a bevel on one long side and one short side. I use this as a sanding block for various grits of sandpaper to clean up the balance of the solder. The long bevels allow me to get in tight at the joint of the rib and the barrels. I don't use stones as the solder tends to load them up just like a grinding wheel and ruins them. The sandpaper works great.
