What stains the worst on quartz? Quartz countertops are known for their durability, low maintenance, and sleek, modern look. But as much as we love them for being non-porous and resistant to staining, they’re not completely stain-proof. Certain substances can leave stubborn marks if not cleaned up quickly.

So, what stains quartz the worst? Let’s dive in.


1. Permanent Markers and Ink

Sharpies, pens, and other inks are some of the toughest culprits. If you’re working on a craft or homework at the kitchen counter, be careful — once ink seeps into the surface, it can be incredibly difficult to remove. These kinds of stains often require special quartz-safe cleaners or even professional help.

Pro Tip: Use placemats or a barrier when writing or crafting directly on the countertop.


2. Turmeric and Curry Spices

Bright yellow spices like turmeric can leave an orange or yellow stain that’s hard to get out. The pigment is strong and can linger, especially if left sitting for a while.

Pro Tip: Wipe up spills immediately when cooking with colorful spices, and avoid letting sauces sit on the surface.


3. Red Wine

A classic staining agent — red wine is acidic and has deep pigments that can discolor your quartz if not cleaned up promptly. While quartz is less porous than granite, if wine is left to sit, it can still penetrate over time.

Pro Tip: Keep a soft cloth or paper towel nearby when serving drinks, and wipe up spills immediately.


4. Coffee and Tea

Over time, even light spills from coffee or tea can cause discoloration, especially around seams or if your quartz has a lighter finish. These drinks are acidic and pigmented, a double-whammy for potential staining.

Pro Tip: Daily cleaning with a mild soap and water mix can help prevent buildup and keep the surface looking fresh.


5. Cleaning Products with Bleach or High pH

This one’s a bit different — not a stain, but a damaging agent. Harsh chemicals like bleach, oven cleaners, or products with high pH can discolor the resin that binds the quartz together, leading to dull spots or faded areas.

Pro Tip: Stick with gentle, quartz-safe cleaners and avoid anything abrasive or acidic.


Final Thoughts

Quartz is a resilient and beautiful choice for your home, but like any surface, it benefits from a little TLC. Quick cleanup and using the right products can go a long way in preserving its shine.

Quick Recap of Worst Offenders:

  • Permanent markers/ink

  • Turmeric & curry

  • Red wine

  • Coffee & tea

  • Harsh cleaners

If a stain does happen, don’t panic! Many quartz-safe cleaners and home remedies (like baking soda paste or isopropyl alcohol) can help, but always test in an inconspicuous area first.
