How to Properly Clean Composite Quartz Worktops

Introduction

Composite quartz worktops are a popular choice for homeowners due to their durability, aesthetic appeal, and low maintenance requirements. However, while they are easier to care for than some natural stones, understanding how to properly clean and maintain them is essential for keeping them looking pristine for years. This guide will walk you through the best methods for cleaning composite quartz worktops, ensuring you avoid common mistakes that can cause damage. We’ll also answer frequently asked questions about their care and upkeep.

What Are Composite Quartz Worktops?

Composite quartz worktops are made from engineered stone, a combination of 90-95% natural quartz and 5-10% polymer resins and pigments. This mix results in a non-porous, hard-wearing surface that mimics the appearance of natural stone like marble or granite but with added strength and stain resistance. Quartz worktops are available in a wide variety of colours and patterns, making them versatile for different kitchen designs.

How to Properly Clean Composite Quartz Worktops: Step-by-Step Guide

Use Gentle Cleaning Solutions

Composite quartz worktops are durable, but they are sensitive to harsh chemicals. Using the wrong cleaner can lead to discolouration, dulling of the surface, and even degradation over time. To avoid this, always opt for gentle, pH-balanced cleaning solutions. Mild dish soap mixed with warm water is usually sufficient for day-to-day cleaning. These solutions will effectively remove grease, grime, and light stains without causing harm to the quartz. Additionally, specialised quartz surface cleaners are available, formulated specifically to maintain the shine and protect the resin in the composite quartz.

Using harsh chemicals like bleach or acidic cleaners can break down the resin in the composite quartz, leading to long-term damage. A little care with what products you use can go a long way in maintaining the appearance and durability of your worktop.

Steps:

1. Prepare the solution: In a spray bottle, mix a few drops of mild dish soap with warm water. Make sure the water is not too hot, as extreme temperatures can stress the quartz over time.
2. Spray the surface: Spray the cleaning solution directly onto the worktop, making sure to cover the entire surface area.
3. Wipe it down: Use a soft, non-abrasive cloth or sponge to gently wipe the surface. Circular motions are recommended to avoid streaks and to ensure an even clean.
4. Rinse and dry: Rinse the cloth with clean water and go over the surface again to remove any soap residue. Leftover soap can leave streaks or dull the shine over time.
5. Final drying: Use a dry microfibre cloth to buff the surface to a shine and ensure no moisture remains, which can attract dust or grime.

Tackle Stubborn Stains Gently

Over time, you may encounter tougher stains, particularly from food items such as red wine, coffee, or turmeric, or from accidental spills of oil or grease. These stains should be tackled promptly and with care. Abrasive scrubbers, such as steel wool or scouring pads, can leave permanent scratches on your worktop, and harsh chemicals like bleach or ammonia can break down the resin, leading to dullness or discolouration.

For stubborn stains, it’s important to use a non-abrasive sponge along with a mild cleaner or a quartz-specific cleaning solution. Patience is key when working on tough spots—allow the cleaner to sit for a few minutes before scrubbing to give it time to break down the stain.

Steps:

1. Apply the cleaner: Use either a quartz-specific cleaner or a mixture of mild dish soap and water. Apply the solution directly to the stained area.
2. Let it sit: Allow the cleaner to sit on the stain for 5-10 minutes to penetrate and loosen the debris.
3. Scrub gently: Using a soft sponge or a microfibre cloth, scrub the area in small circular motions. Avoid using excessive force; the goal is to lift the stain without scratching the surface.
4. Rinse thoroughly: Wipe the area with clean water to remove any remaining cleaner and residue.
5. Dry the surface: Buff dry with a clean, soft cloth or microfibre towel.

For tougher stains that persist, a mixture of equal parts vinegar and water can be used. Vinegar has natural cleaning properties but should be used sparingly, as its acidity can wear down the surface’s shine over time. Make sure to rinse thoroughly if you opt for vinegar.

Clean Up Spills Immediately

While composite quartz worktops are designed to resist stains, leaving spills on the surface for extended periods can still cause issues. Liquids like red wine, coffee, fruit juices, or oil can seep into the surface over time and lead to permanent stains or discolouration. Even though quartz is non-porous, it’s still a best practice to clean spills as soon as they occur to prevent any possible damage.

When addressing spills, it’s crucial to blot rather than rub. Rubbing a spill can spread the liquid over a larger area, increasing the risk of staining.

Steps:

1. Blot the spill: Use a soft paper towel or cloth to blot the spill. Be sure not to rub, as this could spread the liquid and worsen the stain.
2. Clean with soapy water: After blotting, clean the affected area with your mild soapy water solution.
3. Rinse and dry: Wipe down the surface with clean water to remove any soapy residue, then dry it off with a microfibre cloth to prevent streaking.

Prompt cleaning will prevent liquids from setting in and ensure your worktop stays stain-free.

Avoid Abrasive Scrubbers and Harsh Chemicals

To protect the long-term appearance of your composite quartz worktop, it’s essential to avoid abrasive cleaning tools and harsh chemicals. Materials such as steel wool, scouring pads, or harsh scrub brushes can cause micro-scratches in the resin, dulling the finish. Similarly, chemical cleaners like bleach, oven cleaners, or drain cleaners can degrade the resin and pigments in the quartz, leading to fading and weakening of the surface.

Using the wrong cleaner even once can lead to irreversible damage, so always double-check the products you’re using. Stick with soft cloths and sponges and gentle, non-corrosive cleaners.

Tips:

• Stick to soft cloths and sponges: Always use non-abrasive cleaning tools such as microfibre cloths or soft sponges to avoid scratching the surface.
• Avoid harsh chemicals: Do not use bleach, ammonia, or any products containing them. These chemicals are too aggressive for composite quartz and will damage the resin and pigments over time.
• Stay clear of highly acidic solutions: Citrus-based cleaners and other acidic solutions should be avoided, as they can etch the surface and cause dullness with repeated use.

Remove Dried Debris With a Plastic Scraper

Even with the most diligent cleaning routine, it’s inevitable that dried-on debris like food spills, gum, or even adhesive residue may sometimes get stuck on your quartz surface. While it can be tempting to grab the nearest tool to scrape off the debris, it’s important to avoid using metal tools, which can easily scratch the surface. Instead, opt for a plastic scraper, which is gentle enough to remove stuck-on debris without damaging the surface.

Steps:

1. Hold the scraper at an angle: Use a plastic scraper at a 45-degree angle to gently scrape off the dried debris. Make sure to work slowly and carefully to avoid pressing too hard.
2. Clean the area: After removing the debris, wipe the area with a soft cloth and a mild cleaning solution to ensure any remaining residue is cleaned away.
3. Rinse and dry: Finally, rinse the area with water and dry it thoroughly with a microfibre cloth.

This method is effective for removing dried spills or adhesive without harming the integrity of the quartz.

Polish for a Streak-Free Shine

Once your composite quartz worktop is clean, you can give it an added shine by buffing the surface. While composite quartz doesn’t require polishing to maintain its functionality, a streak-free finish can enhance its appearance, making the surface gleam. If desired, you can use a quartz-safe polish for added lustre. These polishes are specifically formulated to bring out the natural shine without damaging the resin.

Steps:

1. Dry the worktop: After cleaning, make sure the surface is completely dry. Use a dry microfibre cloth to remove any remaining moisture or streaks.
2. Apply quartz polish (optional): If you want to enhance the shine, apply a small amount of quartz polish according to the manufacturer’s instructions. Make sure the polish is suitable for composite quartz surfaces.
3. Buff the surface: Use a clean microfibre cloth to gently buff the surface in circular motions. This will leave the worktop looking glossy and streak-free.

With regular cleaning and proper care, your composite quartz worktop will maintain its shine and appeal for years to come.
