The five don’ts of quartz countertop care

Last Updated on October 26, 2026 by Royal Stone Care

If you’ve recently bought a quartz countertop for your bathroom or kitchen, congratulations! As a result, you’ll love the elegance this hardwearing stone can lend your home.

In terms of looking after your worktops, and keeping them looking their best, so here are the five top things NOT to do:

• Don’t throw away the manufacturer’s warranty

Quartz counters frequently come with a manufacturer’s warranty. You should hang on to this and make sure you keep it somewhere safe. That will help ensure a long life and protection for your investment in the unlikely event of anything going wrong.

• Don’t use common household cleaners

Some of the chemicals in regular cleaning products may loosen the resins, stone pieces and polymers used to make quartz slabs. Use something that’s specially formulated to be used on quartz.

• Don’t use harsh scouring pads

While quartz is a durable material, and you may feel strong scouring pads would do a good job on removing tough stains, the finish may become scratched or dull. Use a soft nylon brush to shift stubborn marks.

• Don’t use sharp metal objects in cleaning

We’re sure you wouldn’t anyway, but don’t use a metal scraper to remove caked-on spillages or stains. Stick to plastic items instead. Metal could seriously damage the natural stone surface.

• Don’t seal your quartz countertops

Our customers often asked about sealing their countertops. Unless your worktops are a textured or honed quartz surface, they don’t need to be sealed, unlike some other natural stones. The factory finish should last for years and years if you clean the surface sensibly and often.

Quartz maintenance myths busted

When it comes to quartz maintenance, though, there are a few lingering myths. Here, we try to bust them:

Quartz easily stains

Because it’s non-porous, quartz resists staining better than many other natural stones, even from liquids such as coffee and wine.

Sodium hydroxide and other permanent markers can leave permanent stains, and we’d certainly urge taking care generally. But, with normal use, staining shouldn’t be an issue.

By the way, this natural stone surface also offers the additional benefit of being non-porous. That makes it more hygienic since it’s less likely to harbour potentially harmful bacteria.

Quartz is heat-resistant

The resin which binds this stone as used in most homes will turn white if it becomes too hot. So you should NEVER put hot pots or pans straight on to your quartz countertop. Use place mats or trivets every time.

Sunlight will damage my countertop

Not so. Quartz is designed to be UV-resistant, and so is ideally suited to a good range of indoor applications, even in rooms which get a lot of sun. If you were using this stone outdoors, with prolonged exposure to direct sunlight, that’d be a different matter. (Especially with darker colours.) But you’re not – so relax!

Quartz doesn’t scratch at all

It’s true that the strength of this natural stone is considerable. In fact, it’s considered pretty much indestructible. So it is scratch-resistant. But that doesn’t mean it won’t ever scratch. Especially if your countertop is in a solid dark colour with a tight grain, it can scratch. What’s more, this can be hard to fix.

Don’t drag anything heavy like a ceramic pot over your countertop. If anything gritty gets on the surface, clean it up right away. Never use abrasive pads or cleaners.

Finally, if you do get a scratch on your worktop, call in a quartz repair professional to help.

Quartz is prohibitively expensive

Again, not necessarily so. Many prices are similar to a mid-range granite. Shop around and you should find quartz worktops are cheaper than you thought.

All manufacturers are the same

While all quartz producers basically use the same machinery, their processes and chemical formulations vary. That means differences in colour, price, look and finish.
