If you’ve invested in onyx for your Toronto home, you already know what makes this stone so special. That gorgeous translucent glow, those dramatic veins that catch the light—onyx isn’t just a countertop or backsplash, it’s a conversation piece. But here’s the thing: this stunning natural stone needs a bit more TLC than your typical granite or quartz.
At Onyx & Beyond, we’ve worked with countless homeowners across North York and the GTA who’ve fallen in love with onyx. We’ve also gotten plenty of questions about keeping it looking its best. So let’s talk about how to protect your investment and keep that luxurious stone looking showroom-fresh for years to come.
What Makes Onyx Different?
Before we dive into care tips, let’s talk about why onyx needs special attention. Unlike the granite countertops you might be used to, onyx is softer and more porous. It’s made mostly of calcite, which means it’s more like marble than granite in terms of durability.
Think of it this way: onyx is that gorgeous friend who turns heads everywhere but needs a little extra care. It’s worth it, but you need to know what you’re working with.
Your Daily Onyx Care Routine (It’s Easier Than You Think)
The Quick Clean
Good news—daily maintenance is simple. After cooking or using your onyx surfaces, just wipe them down with a soft microfiber cloth and warm water. For a deeper clean, use a pH-neutral cleaner specifically made for natural stone. You can find these at most home improvement stores across Toronto, or ask us at Onyx & Beyond for recommendations.
The Golden Rule: Act Fast on Spills
This is the big one. When something spills on your onyx—especially coffee, wine, orange juice, or anything acidic—don’t wait. Grab a soft cloth and blot (don’t wipe) it up immediately. I mean right away. Acidic liquids can start etching your onyx surface in minutes, leaving dull spots that are tough to fix.
Protection is Everything
Always use coasters under your drinks. Always. Even that morning glass of water can leave rings if it sits there long enough. Same goes for hot dishes—use trivets or cutting boards. Your onyx might look tough, but trust me, it’s more delicate than you think.
Sealing Your Onyx: Your Stone’s Best Friend
Here’s something many Toronto homeowners don’t realize: onyx needs to be sealed regularly. When we install onyx countertops or vanities in North York homes, we seal them right away. But that seal doesn’t last forever.
How Often Should You Reseal?
Most onyx surfaces need resealing every 6 to 12 months, depending on how much you use them. A bathroom vanity that just holds your toothbrush? Maybe once a year. A busy kitchen island? Probably twice a year.
The Water Test
Not sure if your onyx needs resealing? Try this: put a few drops of water on the surface and wait 5-10 minutes. If the water darkens the stone or soaks in, it’s time to reseal. If the water beads up, you’re still good.
Always use a penetrating sealer made for calcite-based stones (that’s marble, travertine, and onyx). When in doubt, give us a call—we’re happy to recommend the right products for your specific stone.
What to NEVER Use on Your Onyx
Let’s talk about the stuff that’ll wreck your beautiful onyx faster than you can say “DIY disaster”:
Skip These Cleaners:
- Anything with vinegar (yes, even that “natural” cleaning recipe from Pinterest)
- Lemon juice or citrus-based cleaners
- Bleach
- Ammonia
- Your regular bathroom or kitchen spray cleaners
- Anything that says “acidic” or has a pH below 7
Avoid These Tools:
- Steel wool or abrasive scrubbing pads
- Rough sponges
- Magic erasers (they’re too abrasive)
Other No-Nos:
- Leaving standing water on the surface
- Putting hot pots directly on the stone
- Cutting directly on the surface
When Things Go Wrong: Fixing Etching and Damage
Okay, so maybe you forgot about that glass of orange juice, or someone used the wrong cleaner. It happens. Don’t panic.
For Minor Etching:
Light etching (those dull, rough spots) can often be buffed out by a professional stone restoration company. We work with several great ones in the Toronto area who can bring your onyx back to life.
For Deeper Damage:
Scratches and deeper etching need professional honing and repolishing. It’s not a DIY job, but the good news is that onyx can usually be restored to look brand new.
Different Spaces, Different Care
Onyx Kitchen Countertops
If you’ve got onyx in your kitchen (bold choice—we love it!), you’ll need to be extra vigilant. Use cutting boards for everything. Keep a stack of coasters handy. Consider placing decorative trays where you prep food to catch spills before they hit the stone.
Onyx Bathroom Vanities
Bathrooms are actually a great spot for onyx because there’s less acid exposure. That said, watch out for cosmetics, perfumes, and hair products. Many contain harsh chemicals that can damage the stone. Keep these items on a tray, and wipe up any spills right away.
Backlit Onyx Features
If you’ve got a backlit onyx wall or feature (one of our favorite installations), remember that the translucent quality that makes it so stunning also means stains might show through. Extra care with sealing is crucial here.
Professional Maintenance Matters
Even with perfect home care, your onyx should get professional attention once a year. A stone care specialist can:
- Deep clean the stone
- Reseal it properly
- Catch potential problems early
- Apply protective coatings if needed
Think of it like getting your car serviced—a little preventive maintenance goes a long way.
Living with Onyx in Toronto
Toronto’s hard water can be tough on natural stone. You might notice mineral deposits building up, especially in bathrooms. A pH-neutral stone cleaner will handle these better than DIY solutions.
And yes, our winters are rough, but if you’ve got onyx inside (where it should be), you’re fine. Just keep an eye on humidity levels and make sure your sealant is in good shape.
The Bottom Line
Look, onyx isn’t the easiest stone to maintain. But if you ask any of our clients in Forest Hill, Rosedale, or anywhere across the GTA who’ve chosen onyx for their homes, they’ll tell you the same thing: it’s absolutely worth it.
A few minutes of daily care, some common-sense precautions, and regular sealing will keep your onyx looking incredible. And when you’re standing in your kitchen at sunset, watching that natural light filter through your backlit onyx backsplash, you’ll understand why this stone has been prized for centuries.
