I have a problem. My joints are dirty down inside of the joiners. Is there a way I can spray something on them to clean down inside??? If not is there something I can do that doesn't involve ripping my track apart???
But, there is no need to go to that level of effort.
Clean the areas to be soldered really well with a dremel/wire wheel, or just scratch them shiny with a screwdriver tip.
I use 16 gauge "bond" wire so there is no need to strip it. Cut the piece to lenght to span the joiner. Put solder paste on the tips of the wire and rub it onto the track where you cleaned it.
I use a 325 watt Weller gun. Apply heat to the track and touch the solder to it until the solder flows freely. If you use 63/37 (instead of 60/40) solder, the melting point is a little lower so it flows quicker. I use my fingers to put the end of the cut jumper in place into the molten solder and let it cool a moment.
Now heat the rail on the other side of teh joiner and apply solder to the rail until it flows easy. Using a small screwdriver, push the other end of the jumper wire into the molten puddle. Remove the heat and hold the wire in place a moment (with the screwdriver) until the solder solidifies. Then move on to the next one. Once you've done a few, you don't even melt the tie plates. /DesktopModules/NTForums/themes/mls/emoticons/wow.gif
Matt, you did not say brass or stainless or NS or aluminum rail.
You did not mention brand of track.
I'll assume brass Aristo or USAT
There are inexpensive rail clamps that can be added without disturbing the track, and you can take a joiner off with a screwdriver, again without disturbing the track. Aristo makes new clamps that are inexpensive, and the 2 screws are pointing up.
