KPL KNIFE SHIELD - Corrosion Preventive Knife Cleaner Food Safe Protectant for Preventing Rust and Degreaser Oil Polisher skin-friendly Water Based Cleanser, 4 FL OZ

I use this to clean up my knives when they get gunked up a bit. Takes heavy tape glue residue off with ease. I also use it as a conditioner. I have several knives in the collection, mostly Spyderco. I have a range of knife steels and this works well on all of them. I follow the directions on the bottle with great results. I needed something to protect tool steels that do not have much corrosive protection in the metallurgy. Specifically I have had issues with CPM Cru-Wear corroding over a weekend of hiking in humid conditions. This treatment gives me confidence to carry and store higher end tool steel blades without worry.It is super easy to use. Spray on the blade and let sit for several seconds and wipe off and done. I did find that it is easy to leave too much on the blade if you don't pay close attention to wipe it completely clean before fully drying. If you leave it smeared on the blade without fully removing visible residue and it dries, it is best to reapply and start over as it is hard to buff off with a rag.Really great stuff! Will buy more KPL stuff soon for the collection!

This product leaves a nice barrier or coating on the steel. Spray it on, and spread it over the steel. Let it dry. No you are good to go. May have to touch up the cutting edge every now and then.

…even if it does smell like burnt belly button lint.

Great product. Nice finish. Leaves a bit of a tangible residue on blade and fingers, but this is expected for a product that aims to also protect the blade from rusting.

With two sprays on a 3" by 3" jewelry cloth it cleaned up five kitchen knives that have never received attention in three years of ownership. They look much better now and I hope the product helps get rid of rust. Assuming it works, I'm satisfied.
