Larry, the nursery folks down here use full strength alcohol, making sure to
clear off any debris on the blade as well.

I have a couple apple trees infected with fire blight. I want to prune
the diseased limbs off, and know I should disinfect my pruning tools to
keep from spreading the disease to healthy trees.

So what do I use to disinfect the tools? Paint thinner? I have a big
propane burner, but don't want to take the temper out of my tools or melt
fiberglass handles.
