How to remove a white stain on black granite caused by lemon juice

Granite is a beautiful kitchen surface that gives the room a dramatic quality. Unfortunately, it can also stain quite easily. Lemon juice can create a white stain on black granite. The juice can cause corrosion to the granite. Follow these steps to remove a lemon juice stain from your black granite.

Make a paste of baking soda and peroxide and use it to lightly scrub the stain with a microfibre cloth. The purpose of this is to buff away the damaged surface.

Leave a thin layer of cleaning paste on the stain overnight. Cover it with the microfibre cloth. This will draw any colour out of the stain.

Use a dry microfibre cloth to polish the white stain on your black granite.

Use granite sealer to polish and protect the area from future damage.


Immediately clean up stains. Sitting acids (lemon juice, fruit punch) can cause stains that are very difficult to remove.


Do not use any lemon products on granite because the granite is porous and lemon juice will ruin the finish.
Do not use an ordinary kitchen cleaning product to clean granite.
