That sort of stuff does best with electrolysis.
A handle would improve its usefulness greatly
Thanks guys. I have another one I found. Used a cup brush on it. Soaked it in used motor oil- family standby- it's sitting on the bench. I try to keep it coated. Transmission fluid is something I've always heard. Gonna try that.
Soak in vinegar for a week, it’ll clean right up, or just wipe it down and put a handle on it like this wall hanger of mine found on the shores of Hudson Bay.
