Polishing granite can be a time-consuming task, particularly if you have a large expanse of tile in your home. The idea of using car polish on granite surfaces might seem like a convenient, multi-purpose and cost-effective solution. But can you use car polish on granite? You can, but shouldn’t. Here’s why:

Understanding Granite

Granite is a hardy natural stone used for kitchen benchtops, bathrooms, flooring, pool coping and outdoor paving. It is a hard and durable material that is resistant to scratches, heat, and stains. Granite is formed from molten magma that cools and solidifies over time. It is composed of several minerals, including quartz, feldspar, and mica.

Granite comes in a variety of colours and patterns, making it a versatile material for design. It is also relatively easy to maintain with regular cleaning and sealing. However, it is important to use the right cleaning products and techniques to avoid damaging the surface.

When it comes to polishing granite, it is essential to use products that are specifically designed for use on natural stone. Car polish, for example, may contain chemicals that can harm the surface of the granite over time. It is best to use a polishing product that is pH-neutral and safe for use on granite.

In addition to regular cleaning and maintenance, it is also important to seal granite countertops to protect them from stains and other damage. A high-quality sealer will help to prevent liquids from penetrating the surface of the granite and causing damage.

Common Chemicals in Car Polishes and How They Affect Granite

• Silicones: These are often used for their water-repellent and gloss-enhancing properties. While they may provide a temporary shine, silicones can build up over time, creating a film that actually attracts more dirt and grime.
• Petroleum Distillates: These solvents are used to break down grime and oxidation. These can penetrate the porous surface of untreated granite, leading to potential staining and long-term damage.
• Abrasives: Aluminium oxide or other mineral substances are used to remove surface imperfections. The abrasives in car polish are generally too harsh for granite and can scratch the surface, leading to a dull appearance.
• Waxes: Carnauba or synthetic waxes are added for protective coating. While waxes may offer a temporary protective layer, they can also yellow over time, especially when exposed to sunlight, altering the natural colour of the granite.
• Acids and Alkalines: Some polishes contain mild acids or alkalines to remove stubborn stains or oxidation. Granite is sensitive to pH imbalances. Acids can etch the surface, while alkalines can break down the natural minerals in the stone.

Why Car Polish is Not a Good Idea for Granite

• Chemical Incompatibility: The chemicals in car polish are formulated specifically for automotive paint and are not suitable for the mineral composition of granite.
• Long-Term Effects: Using car polish on granite can lead to a range of issues from discolouration and scratching to a breakdown of the stone’s natural properties.
• Cost of Rectification: Should damage occur, the cost of professionally restoring the granite can be significant, far outweighing any perceived short-term savings from using car polish.
• Food Safety: If you plan to use car polish on a granite surface that comes into contact with food, you need to be especially careful. Car polish is not designed for use on food surfaces, and it may contain chemicals that are not safe for consumption. Even if you thoroughly clean the surface after using car polish, there may still be traces of chemicals that could contaminate your food.

Correct Care for Granite Surfaces

Most granite can be cleaned with a simple mix of dishwashing liquid and water. Avoid using abrasives on granite, they can dull the stone. Avoid using the following household cleaning products on your granite surfaces:

• Vinegar (a natural acid that can cause etching to your granite)
• Ammonia (and all-purpose cleaners which contain ammonia)
• Window cleaners
• Bleach
• Essential oils

Alternative Products for Granite Care

While car wax or polish may be tempting to use on your granite surfaces, it’s important to consider alternative products that are specifically designed for granite care. There are many granite cleaning products on the market that can help you maintain your granite in between professional cleaning, polishing and sealing.

Here are a few options to consider:

Granite Cleaners

Granite cleaners are specifically formulated to clean and protect granite surfaces without damaging them. They are pH-balanced, non-toxic, and safe for use on all types of natural stone. Some popular brands include Bar Keepers Friend, Hillmark and Guardsman.

Granite Polishes

If you’re looking to enhance the shine of your granite surfaces, consider using a granite polish. These products are designed to bring out the natural beauty of your granite and provide a long-lasting shine.

Granite Sealers

Granite sealers are designed to protect your granite surfaces from stains, spills, and other damage. They work by creating a barrier that prevents liquids from penetrating the surface of the granite. At Clean Seal Australia, we use penetrating sealers rather than topical sealers. Penetrating sealers, also known as impregnating sealers, are formulated to penetrate the porous surface of the granite, filling the microscopic pores and capillaries without altering the natural stone appearance.

Topical sealers, on the other hand, form a protective layer on the surface of the granite. They can cause granite to become slippery when wet, and should never be used on floor tiles, or in bathrooms and wet areas. While they offer some level of protection, topical sealers are not as durable or effective as penetrating sealers.

If you are going to use an interim sealing product in between professional sealing (you shouldn’t need to), always choose a penetrating sealer.

Your Granite Can Last a Lifetime

So, you’re thinking about using car polish on your granite surfaces? While it might seem like a quick fix, it’s really not the best idea. Car polish has chemicals that aren’t meant for granite and can do more harm than good. If you want to keep your granite looking its best, it’s worth getting help from the pros.

At Clean Seal Australia, we know exactly how to clean, polish, and seal your granite so it stays looking great for years. Trust us, your granite will thank you!
