Rust Clean 115 g – rust remover for knives and metal
Code: KNTN-KB-402Product detailed description
Japanese cleaning paste with a mild abrasive effect helps remove surface rust, oxidation, water stains and dirt from kitchen knives and other metal items.
Rust Clean 115 g is a practical product designed for cleaning metal surfaces and removing light to moderately heavy surface corrosion. It is particularly useful for caring for kitchen knives made of carbon and semi-stainless steel, which may begin to oxidise when exposed to moisture and acidic foods.
The paste contains fine abrasive particles that, when used correctly, mechanically loosen rust, stains and deposits. It helps restore the clean appearance of the blade without the need to immediately resort to coarse grinding.
Rust Clean can also be used on some stainless steel blades and other unpainted metal surfaces. However, before treating the entire item, we always recommend testing it on a small, less visible area.

Main benefits of Rust Clean
Removes surface rust
Helps loosen light to moderate surface corrosion from metal blades.
Cleans stains and oxidation
Helps remove water marks, dark stains and other surface dirt.
Easy application
Usually, only a small amount of paste and a fine chamois or soft cloth are needed for treatment.
For several types of steel
Suitable mainly for carbon and semi-stainless blades, and after prior testing also for many stainless steel surfaces.
When should you use Rust Clean?
Rust can form on a knife even within a relatively short period of time. The most common causes are leaving the blade wet, insufficient drying after washing, storage in a damp sheath or prolonged contact with acidic foods.
| Surface condition | Is Rust Clean suitable? | Recommended procedure |
|---|---|---|
| Small rust spots | Yes | Use a small amount of paste and gentle, controlled pressure. |
| Water marks and stains | Yes | Carefully polish the surface with a soft cloth or chamois. |
| Natural patina | Depending on the desired result | The paste may lighten or remove the patina. If you want to preserve it, do not use the product. |
| Deep pitting corrosion | Only partially | The paste removes surface oxidation, but damaged metal may require professional restoration. |
| Painted or decorative surface | No | The abrasive effect may damage paint, surface treatment or decoration. |
How to use Rust Clean correctly
- Wash and dry the blade first. Remove grease and loose dirt.
- Shake the product before use. This distributes the abrasive particles evenly.
- Apply a small amount of paste to a fine chamois or clean soft cloth.
- Treat only the affected area. Use light to moderate pressure and check the result continuously.
- Wipe away any remaining paste with a clean part of the cloth.
- Rinse the blade thoroughly under running water.
- Dry the knife immediately with a clean, dry towel.
Marek's tip
For the best results, I use a fine chamois. It follows the surface of the blade well, spreads the paste evenly and allows precise control of the pressure. Unlike a coarse cloth, it does not leave a pronounced texture on the surface.
For a small rust spot, you can also work directly with the pad of your finger while wearing a thin nitrile glove. Your finger provides very good control over the application area and the pressure used. Spread the paste only across the flat surface of the blade and never move your finger against the edge.
Marek Šmíd, Dellinger.cz
Safety when cleaning a knife
Always place the knife on a stable surface and secure it against movement. Hold the blade by the spine or handle and work away from the sharp edge. Never move your fingers or cloth against the edge.
If you have sensitive skin, wear protective gloves. Keep the product out of reach of children and use it only for its intended purpose.
Chamois or ordinary cloth?
| Application material | Advantage | Suitable use |
|---|---|---|
| Fine chamois | Follows the surface well and allows even application. | Recommended choice for routine cleaning of the entire blade surface. |
| Soft cotton cloth | Easy to obtain and absorbs paste residue well. | Routine cleaning and final wiping of the surface. |
| Finger in a nitrile glove | Provides precise control of pressure and the application area. | Local treatment of a small stain away from the edge. |
Which surfaces should the product not be used on?
Rust Clean has an abrasive effect and is therefore not suitable for all materials and surface finishes. Do not use it without prior testing on:
- painted and coloured surfaces,
- decorative surface finishes,
- polished surfaces sensitive to fine abrasives,
- gold-plated, plated or otherwise surface-treated parts,
- handles made of wood, plastic or composite materials,
- surfaces where you want to preserve the original patina.
For Damascus, etched, engraved and hand-finished blades, first test the paste on a small area. The paste may change the contrast of the layers, the patina or the character of the surface finish.
What should you do after removing rust?
After cleaning, it is important to remove all remaining paste. Rinse the blade thoroughly, wash it by hand and dry it immediately. On carbon steel knives, you can apply a very thin layer of suitable protective oil once the blade is completely dry.
If you use the knife for food preparation, choose only an oil suitable for food contact and wash the blade again before the next use.
Dry after use
Do not leave the knife wet on the worktop or in a dish rack.
Store in a dry place
Do not store the blade in a damp sheath or tightly closed packaging.
Check the blade
Remove small rust spots as soon as possible before corrosion spreads deeper into the material.
When is Rust Clean no longer enough?
The product is intended mainly for surface corrosion and stains. If rust has formed deep pits, affected the edge or caused significant damage to the blade, polishing alone may not be sufficient.
In such cases, professional regrinding, surface restoration or edge repair may be necessary. You can find additional knife maintenance equipment in the knife sharpening and kitchen knife accessories categories.

Frequently asked questions
What is Rust Clean intended for?
It is used to remove surface rust, oxidation, stains and some deposits from knives and other suitable metal surfaces.
Is the product suitable for carbon steel?
Yes. Carbon and semi-stainless blades are among its main applications because they are more susceptible to rust formation.
Can Rust Clean be used on stainless steel?
It can be used on many stainless steel surfaces, but always test it first on a small, less visible area.
Will Rust Clean also remove patina?
It may lighten or remove it because it has a mild abrasive and polishing effect. If you want to preserve the patina, do not treat that area.
What is the best way to apply the paste?
Marek recommends a fine chamois. It spreads the paste evenly and makes it easy to control the pressure on the blade.
Can the paste be applied with a finger?
For precise treatment of a small stain, you can use the pad of your finger while wearing a thin nitrile glove. Never move your finger against the edge.
How much pressure should I apply?
Start with light pressure and check the result continuously. Excessively strong pressure may alter the blade's surface finish.
Can the product be used on a Damascus blade?
Only after careful testing. The abrasive effect may change the contrast of the Damascus layers, etching, patina or hand-applied surface finish.
Is Rust Clean suitable for deep corrosion?
It removes surface oxidation, but it cannot repair deep pits or material damage. Such a blade may require professional restoration.
What should I do after cleaning?
Remove the remaining paste, rinse the blade thoroughly, wash it by hand and dry it immediately. A suitable protective oil can then be applied to carbon steel.
Is the product suitable for painted surfaces?
No. The fine abrasive may damage paint, colour, decorative surfaces or other sensitive finishes.

Craftsmanship and materials
Kanetsune Seki knives combine modern manufacturing precision with attention to blade geometry, edge grinding, knife balance and comfortable grip. Individual series differ in blade construction, steel type, hardness, edge shape and handle material.
The range includes stainless steels for easier maintenance, multi-layer blades, Damascus constructions and traditional carbon steels. Selected models use materials such as VG-10, SG2, Aogami or Shirogami, valued for sharpness, hardness and the ability to take a very fine edge.
Handles differ by model series. Kanetsune uses both traditional Japanese wooden handles and more modern Western-style constructions. Selected knives feature materials such as magnolia, rosewood, pakka wood or composite materials.
Care for Kanetsune Seki knives
As with most quality Japanese knives, proper maintenance is important. We recommend washing Kanetsune knives by hand, drying them immediately after use and not storing them loose in a drawer without edge protection. Carbon and multi-layer blades should be protected from moisture.
- Hand washing: do not wash the knives in a dishwasher and dry them immediately after use.
- Suitable cutting board: use a wooden or high-quality plastic board, not glass, stone or ceramic.
- No hard ingredients: do not use Japanese kitchen knives on bones, hard or frozen foods unless they are explicitly designed for it.
- Edge protection: use a sheath, saya, magnetic holder, block or edge guard.
- Sharpening: water sharpening stones are ideal for maintaining sharpness.
- Blade oil: for more sensitive blades and longer storage, use a very thin layer of protective oil.
