Start every stain the same way: blot up what you can, then clean the spot with warm water, a little mild dish soap and a soft cloth. Most marks on quartz, granite, porcelain and laminate come off at this stage, especially if you catch them early. Only if that fails should you move to something stronger, and then only to a product your countertop’s manufacturer approves, tested first in a spot nobody will see.
What you should never reach for depends on the material. Bleach, oven cleaner and scouring pads can damage quartz and laminate, and acidic cleaners such as vinegar can dull natural stone. Below is how to handle common stains on each surface, and when to stop and call a professional instead.
Five rules for any stain
- Know your material. The right method for granite can damage laminate. If you’re not sure what you have, check your paperwork or ask us.
- Blot, don’t rub. Rubbing spreads a spill and can push it further into porous stone.
- Start gentle. Warm water and mild dish soap first. On a dried spill, let the soapy water sit for a few minutes before wiping.
- Test first. Try any new product in a hidden spot, such as a corner behind the kettle, and check the result before going further.
- One product at a time. Rinse with clean water between attempts, and never mix cleaning products. Some combinations, such as bleach and ammonia, release dangerous fumes.

Quartz
Quartz is non-porous, so most stains sit on the surface rather than soaking in. Patience and a soft cloth usually win.
- For everyday marks, use warm water, mild dish soap and a soft or microfibre cloth.
- For dried-on food, gum or paint, let water soften it, then lift it with a plastic scraper. Never use a metal blade.
- If a mark remains, use a non-abrasive cleaner made for quartz, following your product’s care guide.
Avoid bleach, oven cleaner, drain cleaner, scouring powders and abrasive pads. Most quartz manufacturers warn against harsh chemicals, which can dull or discolour the resin that binds the stone. If something harsh does spill on quartz, rinse it off with plenty of water right away.
A pale or yellowed patch near the stove is often a heat mark, not a stain. Quartz contains resin, and direct high heat can mark it in a way cleaning won’t fix. Call us before you try to scrub it out.
Granite
Granite is natural stone and slightly porous, which is why it’s sealed. A good seal buys you time to wipe up a spill before it soaks in, but it doesn’t make the stone stain-proof.
Granite stains usually fall into two groups:
- Oil-based stains from cooking oil, butter or cosmetics darken the stone.
- Water-based stains from coffee, tea, wine or juice leave a tinted mark.
For both, blot immediately, then clean with a pH-neutral cleaner made for natural stone. Skip vinegar, lemon juice and other acidic cleaners.
If a stain has set in, the usual approach is a poultice: a paste spread over the stain, covered and left to dry, drawing the stain out of the stone as it does. Buy one made for natural stone, follow its directions exactly and test it in a hidden spot first. If the stain hasn’t lightened after a second try, stop and call a professional.
A dark patch that appears after cleaning and fades as it dries is usually water the stone has absorbed. If water darkens your granite quickly, it’s probably time to reseal. Our countertop care guide covers sealing.
Stain or etch?
A dull, lighter spot that feels slightly rough isn’t a stain. It’s an etch, where an acid has reacted with the surface. Granite generally resists etching, but some stones sold as granite contain minerals that can etch, the way marble does. Cleaning won’t remove an etch, and it needs professional attention. Our post on why homeowners choose quartz and granite over marble explains etching in more detail.
Porcelain
Porcelain is fired at very high temperatures and is highly resistant to staining. Most marks sit on top and come off with warm water and mild soap.
The marks people notice most often are grey lines left by metal pots and utensils. These are usually traces of metal left on the surface rather than scratches, and many come off with a non-abrasive cleaner recommended by the manufacturer. Check the care guide for your specific product, since advice can vary with the finish.
Avoid harsh rust removers and strong acids unless your care guide specifically allows them. For more on how the material behaves, see porcelain countertops explained.
Laminate
Laminate has a printed decorative layer under a protective surface, bonded to a particleboard core. It resists most household stains, but the surface is thin and can’t be sanded or polished, so being gentle matters most here.
- Clean with warm water, mild dish soap and a soft cloth.
- For a stubborn mark, some laminate manufacturers suggest a paste of baking soda and water, applied gently and rinsed off. Check your care guide first, and don’t scrub hard, especially on a glossy finish.
- Lift dried-on food or gum with a plastic scraper, using light pressure.
Avoid bleach, which can discolour the pattern, along with abrasive pads, scouring powders and drain or oven cleaners. Keep water from sitting on seams and along the backsplash, where it can reach the core and cause swelling. Some marks, such as hair dye, permanent marker and scorch marks from hot pans, can be permanent on laminate.
Hard water spots
Much of Waterloo Region has hard water, so chalky spots around the faucet are common. Drying the area after use prevents most of them. For built-up spots, use a non-abrasive cleaner suited to your material, and keep vinegar off quartz and natural stone.
When to call a professional
Stop and ask for advice if:
- A stain hasn’t moved after the gentle methods above
- You see an etch, heat mark, burn, chip or crack
- There’s a rust stain
- You’re not sure what your countertop is made of
- A cleaner has left a dull or discoloured patch
Harsher methods can turn a small mark into permanent damage. If we installed your countertop, call us first. Our after-sales support doesn’t end on installation day.
Preventing stains in the first place
- Wipe spills promptly, especially oil, wine, coffee and citrus
- Keep oil and wine bottles on a small tray rather than directly on the counter
- Keep cast iron, metal cans and wet steel wool off the surface to avoid rust marks
