My recipe for protecting razors is a 50/50 mixture of 91% isopropyl rubbing alcohol and a non-toxic lubricant. If 91% alcohol is not available in your area, you can use 70%, but the 91% is much better as it does a better job of removing moisture.

For the lubricant, I use Ultra Lube which is a non-toxic penetrating oil. Other may use Ballistol, a non-toxic gun cleaner/lubricant. Other oils like mineral oil or cammelia oil can be used, but they do not have the same cleaning/penetrating properties of Ultra Lube or Ballistol.

When you apply the mixture, the alcohol helps remove moisture from the blade and pivot pin. Then the lubricant penetrates to clean and protect the steel.

When applying any oil to the pivot area, be careful to apply it only to the area between the scales. Some types of scales may be discolored or damaged by the oil, so keep it away from the outside of the scales.
