Can Simple Green Be Used on Quartz Countertops?

Quartz countertops are popular in many homes for their durability, aesthetics, and ease of maintenance. However, like any surface, they still require proper cleaning to keep them looking their best. Some homeowners wonder if Simple Green, a common household cleaner, is safe to use on quartz countertops. Here is a detailed look at whether Simple Green can be used on quartz countertops.

What is Simple Green?

Simple Green is a non-toxic, biodegradable all-purpose cleaner made from naturally derived ingredients like lemon extract and salt of fatty acid. It is safe for cleaning most household surfaces such as countertops, floors, appliances, outdoor furniture, vehicles, etc.

Some key features of Simple Green:

  • Made from plant-based ingredients that are environmentally safe.
  • Does not contain harsh chemicals like ammonia, bleach, phosphates, etc.
  • pH neutral formula does not damage surfaces.
  • Can be diluted for light or heavy-duty cleaning.

Properties of Quartz Countertops

Before looking at using Simple Green on quartz counters, let’s first understand what quartz countertops are made of.

  • Quartz counters are engineered stone made from 90% ground quartz crystals combined with polymer resins and pigments.
  • The result is a hard, non-porous material that resists scratches, stains, and heat.
  • However, quartz is not indestructible and still requires careful cleaning. Harsh chemicals can damage the surface and dull the shine.

Is Simple Green Safe for Cleaning Quartz?

Simple Green is generally safe to use on quartz counters for regular cleaning due to the following reasons:

1. Non-Toxic Formula

The plant-based formula is non-toxic and does not contain harsh solvents, acids, or abrasives that can etch or dissolve quartz surfaces. When used as directed, Simple Green poses no risk of hazardous fumes or skin irritation.

2. pH Neutral

Simple Green has a neutral pH around 7-8, so it will not degrade the protective quartz sealant or etch the surface like acidic cleaners.

3. Gentle Surfactants

It contains mild detergents that help lift dirt and grease when used with water and gentle wiping. No scrubbing is required that can wear away the finish.

4. Rinses Clean

Simple Green solutions rinse cleanly without leaving behind residue or soap scum buildup. This keeps the quartz sparkling.

5. Versatile Dilutions

Depending on the cleaning needs, Simple Green can be diluted for regular upkeep or used full-strength for tougher messes. This flexibility makes it useful for quartz care.

How to Use Simple Green on Quartz

When using Simple Green All-Purpose Cleaner on quartz counters, follow these best practices:

  • Vacuum or wipe the surface first to remove loose debris.
  • Mix 2-3 tablespoons of Simple Green per quart of warm water for everyday cleaning.
  • Use a soft microfiber cloth, sponge or paper towel to gently wipe the surface.
  • Rinse thoroughly with clean water and dry with a soft towel to prevent streaks.
  • For tougher stains, apply full-strength Simple Green and let sit for 5 minutes before wiping.
  • Always scrub gently in circular motions. Never use abrasive scouring pads.
  • Clean spills promptly to prevent staining.
  • Regularly reseal quartz every 1-2 years with a stone sealer to protect the finish.

Are There Any Risks of Damage?

When used correctly, Simple Green is safe for quartz counters. However, there are some risks to avoid:

  • Letting Simple Green solutions sit for prolonged periods can erode the finish.
  • Using harsh scrubbing pads or brushes can create fine scratches.
  • Hair dyes, nail polish remover or oil-based cleaners can stain if not rinsed promptly.
  • Prolonged exposure to sunlight can degrade the polymers in quartz and cause fading.
  • Using cleaners outside their recommended pH range can damage the protective sealant.

Simple Green Alternatives for Quartz

If you prefer not to use Simple Green, some other quartz-safe cleaners include:

  • Mild dish soap – Dilute a few drops of blue Dawn dish soap per quart of water.
  • White vinegar – Mix 1 part vinegar with 4 parts water for an all-natural cleaner.
  • Hydrogen peroxide – Combine with equal parts water to create a disinfecting solution.
  • Isopropyl alcohol – Useful for removing adhesive residue and tough grease.
  • Specialty stone cleaners – Products like Method Daily Granite Cleaner are formulated for stone surfaces.

Pro Tips for Keeping Quartz Looking Like New

  • Clean up spills quickly before they have a chance to stain.
  • Rinse surfaces after cleaning to prevent chemical residue buildup.
  • Reseal quartz every 1-2 years with a penetrating stone sealer.
  • Use cutting boards and trivets to protect from scratches and burns.
  • Avoid using quartz as a cutting surface to prevent nicks and dulling.
  • Consider applying a quartz wax occasionally for added shine and protection.


Simple Green All-Purpose Cleaner is generally considered safe for routine cleaning of quartz countertops when used correctly. The non-toxic formula will not etch or damage quartz surfaces like other harsh cleaners. However, care should still be taken to avoid scrubbing too aggressively, allowing extended soaking, or using Simple Green outside recommended dilutions. With proper care and regular sealing, quartz counters cleaned with Simple Green can maintain their good looks and durability for many years.

Frequently Asked Questions About Using Simple Green on Quartz Countertops

Can I use undiluted Simple Green directly on my quartz counters?

No, it’s best to dilute Simple Green with water before using it to clean quartz counters. The full concentrated formula may be too harsh and strip the finish. Always test on a small area first.

How often should I clean quartz counters with Simple Green?

For regular maintenance, cleaning quartz with diluted Simple Green once a week is usually sufficient. Clean more frequently for heavy-use kitchens or if you notice dirt building up.

What ratio of Simple Green to water works best?

Most manufacturers recommend diluting Simple Green 3:1 with water. Mix 2-3 tablespoons of cleaner per quart of warm water. Adjust ratio as needed.

Can Simple Green remove hard water marks from quartz?

Yes, a slightly stronger solution of 1 part Simple Green to 1 part warm water can help scrub away hard water stains. Rinse thoroughly after cleaning.

Will Simple Green dull or etch the surface of my quartz counters?

When used correctly, Simple Green will not etch, pit or corrode quartz. Improper use like excessive soaking can damage the finish. Always rinse thoroughly after cleaning.

Can I mix Simple Green with other cleaners like bleach?

It’s not recommended. Simple Green works best on its own. Mixing it with acidic or alkaline cleaners can negatively react and damage quartz.

Does Simple Green leave a film or residue behind on quartz?

Simple Green solutions rinse clean without leaving residue or streaks. Make sure to wipe any excess cleaner and rinse thoroughly with water after use.

How do I get dried Simple Green stains out of quartz?

Dampen a cloth with warm water and scrub to loosen Simple Green residue, then rinse thoroughly. For tough stains, try some baking soda paste and vinegar.

Should I seal my quartz counters after cleaning with Simple Green?

Yes, it’s a good idea to periodically reseal quartz counters every 1-2 years after deep cleaning with Simple Green or other cleaners. Use a granite and quartz sealer.
