Care & Maintenance for Quartz Worktops
The Bottom Line
How to keep your engineered stone looking flawless. Engineered quartz is celebrated as one of the most durable and hygienic kitchen surfaces available today. Whether you have chosen a traditional quartz slab or one of the new, sustainable low-silica mineral blends, your worktops are completely non-porous and will never require chemical sealing. However, because quartz is bound together using advanced polymer resins, it requires a slightly different care routine compared to natural granite or sintered stone. By understanding exactly what cleaning products to use and how to protect the resins from heat, you can keep your pristine marble-effect or solid colour worktops looking brand new for a lifetime.
1. The Golden Rule: Avoid Harsh Chemicals
Because quartz contains polymer resins, exposing the surface to highly acidic or highly alkaline chemicals can permanently dull the factory polish.
What to Avoid
Never use bleach, oven cleaners, drain unblockers, paint strippers or heavy-duty limescale removers on your quartz worktops.
The Daily Routine
For everyday cleaning, the most effective and safe method is simply using a soft microfibre cloth and warm soapy water. Standard washing-up liquid is perfectly safe and highly effective at cutting through daily kitchen grease.
Glass Cleaner
To achieve a brilliant, streak-free shine (especially on dark or highly polished quartz), standard non-abrasive glass cleaner is an excellent finishing spray.
2. Removing Stubborn Stains
While the stone itself is non-porous and will not absorb stains, sticky foods and cooking oils can dry onto the surface.
Dried-on Spills
If food has hardened onto the worktop, do not use a metal scraper or a wire wool scouring pad, as this will scratch the resin. Instead, soak a cloth in warm water and place it over the spill for a few minutes to soften it, then wipe it away.
Tough Marks
For particularly stubborn marks, use a mild, non-abrasive cream cleaner (such as standard Cif) applied to a soft sponge. Gently work it into the mark in a circular motion, and thoroughly rinse the area with clean water immediately afterwards.
3. Protecting Against Heat (Crucial)
This is the most important care instruction for any quartz or mineral surface.
The Thermal Shock Risk
While the natural quartz minerals are heat resistant, the polymer resins binding them are not. Placing a boiling saucepan, a hot roasting tin or a slow cooker directly onto the worktop can cause thermal shock. This can result in a permanent white scorch mark or even cause the stone to crack.
The Solution
Always, without exception, use a heat pad, trivet or stainless steel hot rods to protect your quartz worktops from direct heat.
4. Preventing Scratches and Metal Marks
Quartz is exceptionally hard, but it is not completely scratch-proof.
Use a Chopping Board
Never chop vegetables or slice bread directly on the quartz surface. Not only will this rapidly blunt your kitchen knives, but sharp steel can also leave fine scratches in the polished resin.
Metal Transfer
Sliding heavy pots or aluminium baking trays across a white quartz worktop can sometimes leave grey metallic transfer marks. These look like scratches but are actually metal deposits sitting on top of the stone. These can usually be gently buffed out using a mild cream cleaner.
Quick Reference Care Guide
| Action | Recommendation |
|---|---|
| Daily Cleaning | Warm soapy water and a microfibre cloth |
| Chemical Sealing | Never required (Zero porosity) |
| Using Bleach / Oven Cleaner | Strictly avoid (Will damage the polish) |
| Placing Hot Pans on Surface | Strictly avoid (Always use a trivet) |
| Chopping Directly on Surface | Avoid (Always use a chopping board) |
Key Takeaways
Daily Care
Warm soapy water and a soft microfibre cloth is all you need. No specialist products or chemical sealants are ever required.
Heat Protection
Always use a trivet or heat pad. Never place hot pans directly onto quartz — the polymer resins can scorch permanently.
Chemical Safety
Never use bleach, oven cleaners or limescale removers. These harsh chemicals will permanently damage the polished resin surface.
