A lot of people have asked us on tips to keep their blade rust free and sharp. We tell our clients that we use mineral oils on our rental shavers to help prolong blade life as well as prevent rust (especially in Hawaii). This small bottle of blade oil can last you many months since only a few drops is needed each time. Keep your shave ice machine's blade sharp and rust free with this high quality mineral oil.
Usage: Apply a few drops after each blade change to prevent rust, corrosion and discoloration.
