I have bought a bunch of scrapers at garage sales, so when they got

Today I ran out of clean ones.

How do I clean them up? Or, is there is clever way to stop them from
getting cruddy?

Some things to consider:

1) Don't apply so much glue.

2) Wait till the glue is at least cured into the "green" state before
trying to remove.

3) Use a 1,500 watt heat gun and an 8" dia wire wheel on your bench
grinder to clean scraper blades.
