Copper washer recycle, redux and annealling 200 1985

I save the used ones...(well I guess I save the new ones two)...

When I have a small pile of used copper washers, I heat them up to the real, real hot stage (you don't wanna melt 'em!). Just get them atoms hopping around a bit...then cool 'em real fast. (Copper/copper alloys are backwards of Al and Fe) Water works great, haven't tried goat urine. Either way they'll look ugly.

Then just buff off.......the oxidation (I used 320 grit paper) or come up with a six step EPA approved clean and etch process. Drink slowly.

Never had an oil pan leak. Good for at least three heat cycles. Haven't tried this with Al washer on the 855.
