5. The blade should be removed with the rag.

6. If you want to completely get rid of any rust, you have to prepare another abrasive cloth or steel wool.

8. If you have a lot of oil or dirt, use a clean polishing cloth to remove it.

Using Homemade Rust Remover

If using a homemade rust remover for a knife will be convenient for you, then follow these steps:

1. To make a thick paste, mix a moderate amount of baking soda and water.

 2. If you want to cover all the rusted areas, apply the solution first.

3. Begin scrubbing the blade by taking an old toothbrush. Take note: it is a good idea to perform gentle yet circular strokes.

4. The knife should be cleaned with soapy water after the rust has been wiped out.

 5.Make sure to rinse it with clean water again and dry.

6. Mineral oil that is made for polishing knives can be applied to your knife to prevent it from rusting again. The areas that are rusted must be covered before the solution can be applied.

How to Mirror Polish a Knife

Here are the easy steps on polishing a knife with a mirror finish:

1. Prepare flat stones, very fine grit wet/dry paper and, chrome polish on a leather hone.

2. Use the DC + CC stones for more efficiency.

3. Use the diamond side flattening out all the micro hollows and bumps.

4.  Use the ceramic sides to remove the coarser grit marks from the diamond.

5. You can use the brown ceramic form extra DC stones to have a finer finish than the white CC stones. 

6. Wait for the mirror finish to show up and then, dry and wipe it with a paper towel or polishing cloth. 

7. Repeat the procedure until you get your desired mirror polish in a knife. Maintain it regularly to have an easier mirror finish if you need it someday. 

Note that it is better to use up to 1200P European grit size before honing with chrome polish.

How to Polish a Knife Blade by Hand

Hand-polishing a knife blade can be done for many reasons. One is to remove any nicks or imperfections that might occur during sharpening. Another is to remove scratches or rust that may have accumulated on the blade over time, and a third is to create an aged look.

It's important to know which way the individual steel grain runs before you start polishing as this will determine how you move your hand and the pressure you apply with your fingers. You can polish a knife blade by hand in about ten minutes if it's not too rusty or scratched up, but it may take longer if it needs more work.

Water, soap, and paper towels should be used to wet the metal. The next step is to use a steel wool pad to scrub the metal. The result will depend on how long you go over the surface with it. You can keep polishing until you reach your desired look or leave it at a light polishing for now and come back later to add more layers.

How to Polish a Knife Blade With a Dremel

Before anything else, prepare the things that are needed in this process such as:

  • Goggles
  • Vise
  • Dremel
  • Mandrel part number 401(Optional)
  • Aluminum oxide grinding stone (part number 932)
  • Polishing compound part number 421 (Optional)
  • 1/2" felt polishing wheel part number 414 (Optional)

Here are the easy steps that you should do:

1. Attach the knife to the vise. The vise should be tightened to make sure the knife is held securely for sharpening. And make sure to tighten the vise to secure your workbench while sharpening the knife blade. Prevent accidents as much as possible. 

2. Install the Dremel to the grinding attachment. Fasten the Dremel properly since the rapid rotation will surely fly off when in a loose condition. To begin sharpening, use the proper angle by sharpening one side of the blade with a 24-degree angle or sharpen both sides of the blade using a 12.5-degree angle. Start at the base of the blade closes to the handle, making sure that it is the most comfortable position for you. Then, move the Dremel along the edge of the knife blade while holding your angle. Also, remember to let the blade cool down before doing the second pass on the other side. 

3. To polish your knife blade, use the mandrel, felt pad, and polishing compound for more efficiency. Follow the instructions placed on the polishing compound for better results.

How to Polish a Knife Blades' Scratches

To polish the knife blades' scratches, the first thing you need to do is to make sure that the blade is dry. This will allow you to see the scratches more easily and it will also prevent the rubbing compound from being absorbed into the metal. You can use a towel or paper towel to dry off your blade.

Next, you should scrape away any minor surface rust with a sharpening steel or other metal utensils. This can be done by using light pressure and working through the scratches in a circular pattern. After this, you are ready to start polishing your knife blade with an abrasive material like sandpaper or baking soda.
