Tube Patching Suggestions?

Use ~100 grit sandpaper instead of the metal scraper thing that comes with some patch kits. Stretch
the area to be repaired over firm surface, such as a fence post or the saddle of your bike, and
apply pressure while sanding.

If that doesn't work, switch to a different brand of tube.

By the way, I assume you're letting the vulcanizing fluid (a.k.a. "glue"😉 dry in place BEFORE
putting the patch on. If you put the patch on while the "glue" is wet, it will not adhere properly.

Nail polish remover works well. Rubbing alcohol works for me. In either case I rub the tube hard.
Sanding with sand paper works too. I like to lightly sand tubes for repair with a dremmel tool.
Waiting for the cement to dry is essential. IMO many failed patches are caused by rushing to patch
before the thin coat of glue is dry. Give it 10 minutes or so, more if it is cold or wet. It's best
to let the patch harden at least overnight before using the tube. So, it's good to have a few
spares. These are easy to come by, as they are all too commonly found at the side of the road. If
you don't find them at roadside, just try the LBS trash.

I've tried naphtha and it didn't work. Will kerosene work?

Follow up,

On my last patch job I got so desperate that I used the flame from a cigarette lighter to burn off
the non-stick coating. It worked, but you have to watch it carefully also I'm concerned about the
toxic fumes it may be producing. I think I'll try paint thinner next.
