The most likely culprit is water and air, which happens when you leave your knife outside in the rain or just have poor standards of cleanliness in your home. Rust is the result of the chemical breakdown of iron when it's combined with water and air.

However, this isn't an overnight miracle, it's going to take days or weeks to get an ample amount of rust on your blade. Now we've established that rust is only found on a blade when it's been left to corrode (a sad death for anything much less a good knife), so we know that sanitation needs to be the first priority.

Remember you're rubbing on a sharp rusty object so gloves are REQUIRED. Just get a few tablespoons of baking soda mixed with water will make a paste, apply this to the rust spots on your knife with a cloth.

In fact, several customers have already reached out to us to know whether the formation of rust is related to the quality of the product. Rusting is a natural phenomenon that takes place when iron and oxygen react to moisture.

It is common on knives that are washed in a dishwasher (which, by the way, we do not recommend!). In fact, every knife rusts (unless they are ceramic blades, but they're brittle though), it is only that few steel knives are more resistant than others.

We are here to help you, follow the steps on this page and restore your knife's charm. Rust is due to the oxidation of iron and it occurs when the metal is in contact with water for longer periods.

The only problem of using rusted knives is that all the foods that are cooked will have a metal taste, but it doesn't affect the health nor does it cause any disease. Rust will become harmful only when the blade is in contact with soil, but if the knives are kept in a proper storage space, then there won't be any impact.

The italic acid in the potato will act as an anti- rust on the steel blade. Everyone loves white vinegar; this is a household product par excellence and its benefits are multiple.

We haven’t had the greatest luck with avoiding food/contamination poisoning this year, and I am determined to keep it from striking down another family member. Any knife that is used to cut raw meat goes straight into the dishwasher like a quarantined specimen, and we don’t even think twice about it.

All of these factors ultimately lead to build-up and rust our kitchen knife set. We cook A LOT, and we cannot prep our food knowing that we aren’t living up to our own code of standards.

If my problem stems from attempting to avoid contamination, the last thing I want to do is poison my family with toxic chemicals. Pouring equal parts of each into a small cup, I add the knives and wait 10 minutes or so, depending on the severity of the rust.

After your knife is done soaking, use a soft cloth to wipe away the residue. Some years ago I made this mini Santos in carbon 1010 and stainless 304 with a 5160 core for an order.

I didn't like the way it looked (the inner 5160 cores had switched too much to one side), but since it was 100% functional, I gave it to my webmaster, so he could use it. I've been getting a lot of questions lately on what extra care is needed for this steels' combination, so I asked him to let it rust on purpose and then document the cleaning process to show how easy is to maintain one of these kitchen knives.

We grab the knife, wrap the wool over the blade and pass it back and forth several times under running water. If you need a good, cheap rust remover, here are three sure-fire recipes using everyday household ingredients.

The Spruce / Taylor Serbia Submerge the rusted object in undiluted white vinegar. If the object is too large to do so, liberally spray or dab vinegar over the rusted area.

Pull your object out of its vinegar bath, and use a brush to scrub off any remaining surface rust. The Spruce / Taylor Serbia Mix Borax and lemon juice together to form a paste.

Apply the paste to the rust, and let it sit for at least 30 minutes (longer for rustier objects). Use a brush (a toothbrush works great) to scrub the paste into the rusted object.


The Spruce / Taylor Serbia Slice a potato in half, and sprinkle the cut side with salt or baking soda. The acid in the potato will lift the rust, and the salt (or baking soda) will help scrub it away.

If you're trying to remove rust from your kitchen knives, plunge them into a potato, and let them sit while you go about your day. The Spruce / Taylor Serbia Objects may appear black after being soaked in vinegar or lemon juice but should return to their original color after being rinsed in water.
