I would like to learn how to repair a tube correctly rather than just buying a new tube each time I get a flat, especially at this rate... but, I don't want to keep trying to patch and end up getting another flat if it's a lost cause...
You should have tried to wet the glue with a lighter fluid, gasoline, or another solvent, and rub the glue off. Even without a remnant glue, I wipe the area to be glued with a lighter fluid. Otherwise, putting on a patch is the issue of adhering to instructions: resist putting a patch too early and don't forget that you're patching and let the glue dry out. Keep a reserve of different patch sizes to apply one adequate for the size of a hole.
Personally, I don't feel like tossing a tube that could still work for years, even if it is cheap.
