Why Do Granite Countertops Stain?

Granite, despite its toughness, has tiny natural pores that can absorb liquids if not properly sealed with a sealant or appropriate sealers. While less porous than some other stones, unsealed or worn granite can still let spills seep in, especially if left unattended. Lighter granite shades often show stain more noticeably than darker ones. When liquids penetrate these pores, they can leave visible marks-water might create temporary dark spots that fade, but oils and organic substances can cause lasting discoloration if ignored. Regular sealing with a sealant and sealers forms a protective shield, but even sealed granite isn't foolproof against prolonged exposure to spills.

Types of Granite Stains (Oil, Water, Rust, etc.)


Oil-Based Stains

Spills from cooking oil, butter, or greasy leftovers can be a headache on granite. Unlike water, these don't dry out; they sink deep, leaving dark spots that stick around. Even something like pizza grease or oily lotion can cause the same trouble if not wiped up fast.

Water Stains

Hard water or mineral deposits often leave whitish, chalky marks on granites, especially near sinks or dishwashers. Gentle dish soap, a granites cleaner, and pure water stains might disappear on a sealed surface as they evaporate, but there is a simple way to handle mineral-heavy water, which can leave lasting soap residue if not cleaned off.

Organic Stains

Food and drink spills-think coffee, red wine, fruit juice, or tomato sauce-can create food stain that seep into granites, forming dark, uneven marks. These show up more on lighter granites and need quick action to avoid becoming permanent stain from dyes.

Rust Stains

Rust stain pop up as orange or brown marks, usually from metal items like tools or pans left on wet granites. They're a bit trickier but can be managed with the right cleaning method for natural stone.
