Vinegar + Baking Soda + Salt+ Lemon extract + Water.

After that the knife can be brushed to get a good start surface

After securing the knife, the knife has to be sanded.

Using we and dry emery papers starting from 200 grit to all the way upto 2000 grit

Cutting strips of emery paper and using a support tool, the knife is stroked from inside to out using oil/water to aid the process.

While sanding with water/oil, slush is formed. This aids a lot in polishing the knife.
