What is the best way to clean old traps and not hurt the value? and also looking for jaw for #0 Victor DLS.

Old traps should not be cleaned. It is ok to wash off loose dirt and rust using water.

Using chemicals, even vinegar, will lower the value of collector traps. At least that is the opinion of most collectors.

water and a toothbrush just to remove any loose dirt and rust,you just need one jaw? have a pr of cast

If I clean a trap, I'll use hot, soapy water and a toothbrush. Even better than that is non-chlorinated brake parts cleaner followed by a clean water rinse, and then either a blow or oven dry. Works great, and leaves no tell-tale signs of cleaning. Nor does it hurt the trap's patina. At least, it hasn't on the traps that I've cleaned with it. Try at your own risk, though.

Ya just need one or pair that look the same. and these are just stamped. Do you oil them after washing them?

yes, heavy oil with water displacer (like gun oil) or wd40

Thanks everyone for the info on washing traps. I will try to post some before and after pics.
