Grease stains on unsealed natural stone.
I believe the stone in my bathroom is unsealed. There appears to be a great deal of stains on this stone.
I tried to scrub it with Kaboom and this left streaks. I do not have a spare tile that I can experiment with but the previous owner left what appears to be a tile that is similar to this stone.
I tried to use something from Lowe's and this appeared to brighten the stone but this sample stone was unstained.
A gentleman at Lowe's Recommended Dupont Heavy Duty Acidic Tile Floor Cleaner.
This product is for ceramic and porcelain tile and the ingredients are Deionized Water, Phosphoric Acid, Glycolic Acid, Alchohol Ethoxylate.
It seems to be pretty toxic. I don't know what these stains are from. I do bathe with bottled soap that I mix with olive oil or perhaps it's the minerals in the water that are causing the stains.
I really want to salvage this stone. Do you have any suggestions?
It's most likely the oil that's causing the stains in your stone. What ever you do, don't use the acid, as it will most likely etch your stone tile.
I don't know what your stone is, but all calcium based stones are sensitive to acid.
Really it doesn't matter that your stone was sealed on not as exposure to water and oil daily, it was inevitable that your stone was going to be stained.
My only suggesting would be when you are ready to change your tile, use a porcelain or ceramic tile.
The reason being, you will never have problems with staining with a non-porous material.
Because you use oil in your soap, and natural stones are porous, you will always have a staining problem.
