To Bleach or Not to Bleach: The Dilemma of Granite Worktops

In kitchen aesthetics, granite worktops stand as timeless testaments to durability and elegance. Their natural beauty and robust characteristics make them a popular choice for homeowners seeking both style and functionality. However, when it comes to maintaining these exquisite surfaces, the question of whether to use bleach on granite worktops often arises. In this blog, we’ll delve into the pros and cons, exploring safer alternatives for maintaining the pristine allure of granite. 

The Dangers of Bleach

Bleach has long been celebrated as a powerful disinfectant, capable of vanquishing germs and bacteria with unparalleled efficacy. However, when it comes to granite worktops, the story takes a different turn. While bleach can undoubtedly sanitise your surfaces, it comes at a cost. The harsh chemical composition of bleach can dull the finish of your granite and, in some cases, even alter its colour.

Granite is a natural stone with unique mineral compositions that contribute to its distinctive appearance. Bleach, being a corrosive substance, can react with these minerals, resulting in a loss of the stone’s natural lustre. This effect is particularly noticeable on polished surfaces, where the reflective shine can be compromised by the use of bleach.

A Safer Path to Disinfection

Given the potential risks associated with bleach, it’s essential to explore alternative methods for disinfecting granite worktops. We recommend steering clear of bleach and any products that contain it when cleaning your granite. Instead, consider these safer alternatives:

Mild Dish Soap and Warm Water: 

A simple solution of mild dish soap and warm water can effectively remove dirt and bacteria from your granite worktops without compromising their natural beauty. Use a soft cloth or sponge to gently clean the surface, avoiding abrasive materials that could scratch the stone.

Isopropyl Alcohol: 

For a more potent disinfectant, you can use isopropyl alcohol. Mix a solution of equal parts alcohol and water, apply it to the granite, and wipe away any contaminants. This method is particularly useful for high-touch areas where bacteria may accumulate.

Specialised Granite Cleaners: 

Opt for cleaners specifically formulated for granite surfaces. These products are designed to clean and protect without causing harm to the stone. Always follow the manufacturer’s instructions for the best results.


Having considered the points above, the verdict is clear: using bleach is best avoided. Granite’s allure lies in its natural charm, and using harsh chemicals can diminish its beauty over time. Instead, embrace gentler cleaning methods to ensure the longevity and vibrancy of your granite surfaces. With a little care and the right products, your granite worktops can continue to be the focal point of your kitchen for years to come.
