Can I Use Simple Green on Quartz Countertops?

Quartz countertops are engineered stone surfaces made from quartz particles bound together with resin. Their non-porous nature makes them resistant to stains and etching. However, quartz countertops still require regular cleaning to keep them looking their best. Simple Green is a popular household cleaner, but is it safe to use on quartz?

An Overview of Simple Green

Simple Green is an all-purpose, biodegradable cleaner made from plant-based ingredients like lemon extract and sodium citrate. It is non-toxic and fragrance-free. Simple Green is safe for many surfaces, but it’s important to check the label or manufacturer recommendations before using it.

Here are some key facts about Simple Green:

  • Safe for most surfaces including granite, marble, tile, glass, chrome, and stainless steel when used as directed
  • Non-abrasive formula won’t scratch surfaces
  • Rinses clean without leaving residue
  • Removes grease, grime, oil, dirt, and some tough stains
  • Available in original, diluted ready-to-use, and concentrated formulas

Is Simple Green Safe for Quartz Countertops?

The short answer is yes, Simple Green is generally safe to use on quartz countertops. However, there are some important caveats to keep in mind:

  • Use diluted Simple Green (1:16 ratio) – The concentrated formula can damage sealants and etch quartz. The diluted ready-to-use formula is safest.
  • Avoid abrasive cleaning tools – Soft microfiber cloths, sponges, or paper towels are best to avoid scratching.
  • Rinse thoroughly – Don’t allow Simple Green to sit or dry on the surface.
  • Check manufacturer guidance – Some quartz brands have specific cleaning dos and don’ts.

Simple Green’s website states their all-purpose cleaner is safe for engineered stone and quartz surfaces. Most major quartz manufacturers such as Caesarstone, Cambria, and Silestone also approve diluted Simple Green for routine cleaning.

Step-by-Step Guidelines for Using Simple Green on Quartz

Follow these best practices when using Simple Green to clean your quartz countertops:

  1. Use the diluted ready-to-use Simple Green formula. Check the label to confirm it’s the safer 1:16 dilution ratio.
  2. Apply a small amount directly onto a soft microfiber cloth or sponge. Avoid spraying directly onto the quartz.
  3. Wipe the quartz surface using light, circular motions. Apply more Simple Green to stubborn spots.
  4. Rinse the surface thoroughly with clean water to remove all cleaner residue.
  5. Dry the quartz with a clean soft cloth or paper towels.
  6. For dried spills or stains, let Simple Green sit for 2-3 minutes before wiping to allow it to penetrate.
  7. Once a week, give quartz a deep clean using a pH-neutral stone cleaner made for quartz.

Tips for Keeping Quartz Looking Like New

Taking proper care of your quartz countertops ensures they stay looking pristine:

  • Clean up spills immediately before they have a chance to soak in or stain.
  • Regularly wipe down surfaces using a quartz-safe cleaner.
  • Avoid using abrasive pads, scouring powders, or bleach products.
  • Use cutting boards and trivets to protect from scratches and burns.
  • Re-seal quartz every 1-2 years using a stone sealer made for engineered stone.
  • Handle etching issues right away before they worsen.

Can I Use Other Cleaners on Quartz?

While Simple Green is a good everyday option, other cleaners are also safe for quartz:

  • White vinegar diluted with water makes an effective DIY cleaner.
  • Dish soap like Dawn combined with warm water can lift grease.
  • Hydrogen peroxide helps whiten and disinfect.
  • Rubbing alcohol removes stubborn marks and disinfects.
  • pH-neutral stone cleaners specially formulated for quartz.

No matter what cleaning product you choose, always spot test on an inconspicuous area first. Check manufacturer guidance too. Avoid abrasive chemicals like bleach, alkaline cleaners, acidic solutions, etc.

When to Avoid Using Simple Green on Quartz

There are a few situations where you’ll want to avoid using Simple Green to clean quartz:

  • If the formula is not diluted – stick to the ready-to-use dilution only.
  • If the quartz has a glossy polished finish – it can strip the shine.
  • If you don’t rinse it thoroughly – residue left behind can stain over time.
  • On unsealed surfaces – seal quartz first before using any cleaners.
  • For removing stubborn etching or epoxy stains – use a specialty etching remover instead.

Professional Quartz Cleaning and Restoration

For a deep clean or help with damage, consider hiring a professional quartz restoration service. They have access to more heavy-duty cleaners and tools to re-polish, resurface, and re-seal quartz. Professionals can make quartz look brand new again.

Simple Green is a handy, quartz-safe cleaner for daily maintenance. With proper care, your quartz countertops can stay gorgeous for years to come. Follow the proper dilution, cleaning method, and safety tips outlined above to successfully use Simple Green on quartz surfaces.
