Super fine finish for used stainless steel commercial kitchen equipments

Could you please send us details of buffing or polishing solutions for stainless steel kitchen equipments. We would appreciate if you will let us know where can we buy them. Thanks George

A. Buffing the equipment will impart the desired sheen, and there are many suppliers of the required wheels,compounds, and technical advice.

For the ultimate in providing sanitary equipment though, the sinks could be electropolished, although this may be rather difficult to do in situ. But talk to suppliers of the solutions and technology like Metal Coating Process Corp. and Sifco.

Q. I am restoring jet turbine engines for display purposes. This involves cleaning of 316 and other high alloy stainless steels who has been subjected to high temperatures (600 °C to 900 °C). To remove the brown oxide by abrasive methods is considered impossible on these complicated and thin walled and sometimes plated components (blasting is not an option for this reason). Is there a simple acid bath or simple electro chemical method for removing this oxide without going all the way to electro polishing?
