You can use Alkaline hot potassium permanganate ⇦this on eBay or Amazon [affil links] followed by Mild acid dip or You can also use some proprietary Deruster and De scaling chemical which is Alkaline in nature with Gluconate and chelating agents.

Dear Pravin Kumar;
You can save yourself a lot of trouble by cleaning and phosphating the parts properly before heat treatment; You will not get a scale, rather a hue over the phosphate which comes of easily in vibro. Much better than post heat treatment process which are more troublesome.
