While granite is somewhat resistant to staining, many substances can still manage to leave stains if the surface sealant has weakened over time. True discoloration is caused by prolonged exposure to ultraviolet rays or extreme heat.

How do you remove yellowing from granite?
Mix a poultice paste of baking soda and water (for oil-based stains), or baking soda and peroxide (for others), until it’s as thick as peanut butter. Spread the mixture over the spot, cover it with plastic wrap that you’ve poked a few holes in, and secure it with masking tape. Let the poultice paste stand for 24 hours.
Why did my granite turn yellow?

Can granite discolor?
A. Granite is a hard, nonporous mineral similar to marble and, depending on its source, can be stained, chipped or discolored.
What causes granite to change color?
Why Does It Happen? Even if your granite seems extremely smooth to the touch, it is a natural substance, and on a microscopic level it is uneven and full of holes. The porous surface of stone allows water to cling to it and absorb, darkening the appearance.
Why is my white countertop turning yellow?
You use a lot of bleach to get your bathroom counters clean and white. But you have recently noticed some yellow stains on your normally white bathroom counters.

How do you bring granite back to life?
Give countertops an occasional deep cleaning with a soap scum and mineral buildup remover and treat stains with a polishing compound as needed. Reseal your countertop about every year or, if your granite doesn’t see much action, every few years.
Why is my countertop yellowing?

Waxes and such used to be commonly applied to marble to enhance the shine and provide a bit of surface protection. Old wax needs to be stripped off and the marble cleaned.
Does granite stain easily?
The answer is that while no material is completely 100-percent stain-proof, granite countertops are surprisingly stain-resistant — and that includes light colors, too! The natural stone’s hardness gives granite its resistance to staining.
How do you brighten granite?
To put a shine on your granite, pour a little cooking oil on a soft cleaning cloth and wipe it across the countertop. Buff it gently. This makes the counter a little bit stain-resistant and gives it a glossy shine. Even if you know how to clean countertops correctly, your granite will need to be resealed periodically.
Why is my granite staining?
They are caused by the absorption of materials into the pores of the stone causing it to have a different color from the rest of the countertop. They can either come from spills or prolonged exposure to chemicals. The good news is, once the staining agent is removed, the stain on the granite countertop is gone too.
How do you fix a discolored countertop?

What happens if you don’t seal granite?

- pour a tablespoon of regular tap water onto the counter and let it sit for 10-15 minutes.
- Wipe away water with a dry cloth.

Does sealing granite change the color?
