how to clean up quench oil before tempering?

[ht3jyx]

material 1075, shining washer parts. after oil quench, quench oil gives the parts a not so shine thin layer and looks dirty. if washed with regular hot water which rust prohibitive soap, the tempered parts will show soap scale. if temper without wash, the parts will still have slight blur. is there anyway to deal with the issue.

thanks,

For 1075 material,have you tried forced air quenching. It should be adequate,I suppose.

How about a post-heat treat tumble operation using corn cob grit?
