If you’re washing a marble floor, then use a larger microfiber mop to spread the soapy water over the surface. Soapy water is usually strong enough to eat through soot if you’re cleaning a marble fireplace. Avoid using any acidic cleaners, such as lemon juice or vinegar, since they can leave marks on the marble’s surface.

For a marble floor, use a clean mop head or thoroughly wring out the old head before using it to rinse.

Any water you leave on your marble could absorb into the stone and leave a stain on the surface.

Always follow the directions on the cleaner’s packaging since they may vary. Avoid using other household cleaners like bleach or mineral spirits since they could further damage your marble.

Try to clean up the stain as soon as they happen since they haven’t set in and will be easier to clean up. Ammonia is safe to mix with hydrogen peroxide but avoid using it with bleach or any other cleaners since it could create toxic fumes.

The baking soda and peroxide will help draw the stain out from the stone and lighten the section of marble. Test the baking soda and peroxide mixture on a discreet area of the marble first to make sure it doesn’t leave any marks or damage.

If you can still see a rust stain, you can try applying another poultice to your marble. If the stain persists, then it may be permanent on the surface.

You can also use a rotary buffer to apply the polishing powder more quickly on larger surfaces, like a large tabletop or marble floor.

Some marble manufacturers don’t recommend using steel wool since it’s abrasive and could affect the surface of your marble. Try testing the steel wool in a hidden area of the marble before using it on a scratch.

Using coasters prevents glasses or mugs from forming ring-shaped stains on your marble.
