Soak in White Vinegar

The first step in removing rust from your ceramic or steel knives is to soak them in white vinegar for three hours or overnight.

White vinegar is an effective rust remover due to its acidity, so make sure you use gloves when handling the knife during this process.

Once you’ve soaked the knife for a few hours, take it out of the vinegar bath and use a soft cloth or sponge to gently scrub away any remaining rust spots.

You should also rinse off the blade with warm water after every scrubbing session.

Use Baking Soda

Baking soda is another effective way of removing rust from kitchen knives.

Start by making a thick paste using equal parts baking soda and water in a bowl or small container.

Then, using a soft cloth or sponge, apply the paste liberally onto the rusty areas of your knife’s blade and let sit for one hour before rinsing off with warm water.

This method works best on smaller patches of rust that haven’t had time to spread too much around the blade.

Use Steel Wool

If all else fails, steel wool is always an option as well!

Start by wetting down the steel wool pad slightly with warm water and then lightly rub off any remaining rust spots on your knife’s blade until they have completely gone away.

Make sure not to press too hard while rubbing off the rust spots; otherwise, you may accidentally damage or scratch up your knife’s surface!

Afterward, be sure to rinse off any residue left behind by the steel wool with warm water before drying thoroughly with a soft cloth or paper towel.

Use Lemon Juice

If you don't have access to white vinegar, lemon juice will also work effectively in order to remove rust from your kitchen knives.

Start by squeezing some fresh lemon juice onto a clean cloth or sponge and then rub it into the blade of your knife until all of the rust is gone. To finish off, rinse with warm water and dry thoroughly before use.

Use Saltwater Solution

Salt has natural cleansing properties which make it great for removing rust from metal surfaces such as ceramic or steel knives.

To make a saltwater solution suitable for cleaning your knife, mix 3 tablespoons of salt into 2 cups of hot water until fully dissolved.

Soak your ceramic knife in this solution for 10-15 minutes before taking it out and scrubbing away any remaining rust with steel wool or a stiff brush.

Rinse off the blade thoroughly afterwards and dry it completely before using again as normal.
