Yes, you can use olive oil to polish your stainless steel. But before you start let me share a few things.
Only use a little – more is not better (even Dr. Oz had to learn that you dab it on like perfume.
Use the olive oil on a microfiber cloth – then you can turn it over and remove the excess.
Apply it with the “grain” – stainless steel has a grain to it and you want to apply the olive oil with that grain.
Olive oil will repel fingerprints – your fingers are covered with oil so when you apply the olive oil to the stainless steel – oil can’t stick to oil.
