Even a completely sealed granite countertop can stain if a spill is left to sit for long enough.

Even granite can be marred if spills are left to sit or if surfaces are not adequately sealed. Granite isn’t a particularly porous stone, but, like all natural stone surfaces, it does let liquid in if it isn’t properly sealed. If the water soaks in and darkens your granite, then it’s time to re-seal. Other types of stone are differently affected by potentially staining liquids, so different kinds of countertops may require different care, or be particularly susceptible to certain types of stains.

This is one reason pizza boxes should never be placed on a granite top. If the worker had just spit out a wad of chewing tobacco or been eating some spaghetti with tomato sauce, then there is a chance his saliva contained colored molecules that could stain the granite.

One thing is for certain, do not seal the granite until the surface is stain-free.

These characteristics make them react differently when water soaks into the micro-pores of the granite. The air pressure pushing on the suction cups exacerbated the situation. If saliva was just placed on the top of the polished granite, the air pressure on each side of the granite is the same, and surface tension might minimize the depth to which the saliva would penetrate into the granite.

The moisture of the saliva causes light to refract differently and this is why you see a dark spot. Sealers help to block the pores and micro-cracks in the granite so water and oils sit on the surface. Oil can soak into the cardboard box and then pass into the granite. If this is the case, the granite supplier probably has special cleaners that can be used to remove the stains. Sealing the granite could lock the stain into the stone permanently.

Let the stain absorb into the stone for a minute or two, this is where you can experiment and let it sit for longer for a possibly darker stain.

Sealers, also known as ‘impregnators,’ work by soaking into the stone and forming a protective barrier that keeps out stains and liquids. They can be stained and damaged by acidic substances, despite being sealed. They have a strong odor and have been reported to cause problems with stones that were factory treated with resin. This quality makes them extremely good for repelling liquids, as they sit just beneath the surface of your countertop to provide a protective barrier.

Because they are natural materials, quartz, granite, and marble countertops differ piece by piece.

Typically black granite countertops are extremely dense and do not absorb stains or sealers. Marble and limestone have a calcite-base and may react to acids. Put a few small drops of lemon juice on the counter and observe the reaction. If it does not soak in at all, your stone countertop does not need sealing.
