About a year ago I brought back to life a couple of hatchet heads I found. Both had been sitting neglected for eons - pretty nasty. Read about some stuff called Evapo Rust - a biodegradeable metal cleaning/derusting solution, and decided to give it a try. Followed the directions and soaked the heads for a couple of days, then rinsed with water. Then used a wire wheel and then a buffing wheel - both came out really nice ! EvapoRust after use is put back into the container and can be used over and over again. Cool stuff as it isn't toxic. Found mine at Harbor Freight, but I believe most hardwares stock it now. Good Luck - Bob.
