Quartz countertops are marketed as being extremely durable and low-maintenance. So when stains start appearing, it can be surprising and concerning. However, with a bit of knowledge, quartz staining can often be prevented, minimized, or removed.
What Causes Staining on Quartz Countertops?
There are a few potential causes of staining on quartz countertops:
1. Spills from Dark Liquids
Spilling dark liquids, like red wine, coffee, or juice, can lead to staining if the spills are not cleaned up quickly. The pigments from these darker liquids can seep into the tiny pores and cracks in the quartz surface.
2. Harsh Chemicals and Cleaners
Using cleaners and chemicals that are too abrasive or acidic can damage the protective sealant on quartz, allowing stains to penetrate the surface over time. Things like bleach, oven cleaners, and degreasers should be avoided.
3. Heat Damage
Exposing quartz countertops to excessive heat can damage the resin that binds the quartz together. This damage leads to an increased porosity that makes it easier for stains to occur.
4. Poor Quality Quartz
Lower-quality quartz is more prone to staining issues. The ingredients and manufacturing process may produce a more porous material.
How to Prevent Staining on Quartz Surfaces
Preventing stains on quartz countertops involves following a few best practices:
Use Coasters and Trivets
Always use coasters under glasses, mugs, and bottles. Hot pans and baking dishes should be placed on trivets to prevent direct heat damage.
Clean Up Spills Quickly
Don’t let spills sit on the quartz for extended periods. Blot up liquids immediately using a paper towel or cloth.
Avoid Harsh Cleaners
Stick to mild soap and water or stone-safe cleaners. Steer clear of bleach, ammonia, vinegar, etc.
Reseal When Needed
Resealing your quartz every 1-2 years will replenish the protective barrier.
Choose Quality Materials
Opt for high-end quartz brands known for durability and stain resistance.
How to Remove Stains from Quartz Countertops
If stains appear, try these stain removal techniques:
Baking Soda Paste
Make a paste of baking soda and water and gently rub it into the stain using a soft cloth or sponge. Rinse thoroughly after letting it sit for a few minutes.
Use a 3% hydrogen peroxide solution, undiluted, and let it bubble on the stain for 2-3 minutes before wiping and rinsing. Be careful not to get it on other surfaces.
For oil-based stains, make a mix of warm water and dish soap. Allow it to sit on the stain briefly before scrubbing lightly and rinsing. Repeat as needed.
Lemon juice or a citrus-based cleaner can help break down and dissolve some organic stains. Rinse thoroughly afterwards.
As a last resort, use a polish made specifically for quartz to buff out very stubborn stains. This should only be done occasionally, as over-polishing can damage the surface.
When to Call a Professional
If DIY methods are ineffective at removing a persistent stain, don’t hesitate to call in a professional quartz restoration company. They have commercial-grade stain removal solutions and polishing equipment not available to consumers. This can often remove stains without damaging the surface.
While quartz countertops are less prone to staining than other materials, discoloration can occur under certain conditions. Being proactive about prevention, addressing spills quickly, and using the right stain removal techniques can keep your quartz counters looking like new for years. But when all else fails, calling a professional may be warranted to eliminate those stubborn stains. With some diligence about care and cleaning, quartz countertops can remain in immaculate condition.
