Can You Use Ammonia on Quartz Countertops?

An Overview of Using Ammonia on Quartz

Ammonia is a powerful alkaline cleaning agent. In very diluted concentrations, ammonia-based cleaners can be safe for cleaning quartz surfaces. However, full-strength ammonia should always be avoided, as it can damage and discolor quartz.

Quartz countertop manufacturers generally approve using dilute ammonia solutions for routine cleaning. But they caution against using anything stronger than a 1:20 dilution of ammonia in water. Anything more concentrated than that risks etching or fading the quartz surface over time with repeated use.

Vinegar or pH-neutral stone cleaners are gentler options. But diluted ammonia can give an occasional boost for removing grime if used properly on quartz counters.

Pros and Cons of Using Diluted Ammonia on Quartz

Potential Benefits

  • Helps remove stubborn grease and dirt buildup
  • Cuts through grime from food prep and cooking
  • Sanitizes countertops
  • Typically inexpensive and easy to find

Potential Drawbacks

  • Can dull quartz surface over time if overused
  • Can etch quartz if too concentrated
  • Adds to indoor air pollution if used frequently
  • Has strong odor many find unpleasant

Best Practices for Using Ammonia on Quartz

When using diluted ammonia to clean quartz counters, follow these guidelines:

  • Always pre-test a small inconspicuous area first
  • Mix 1 tablespoon or less ammonia per 1 quart water (1:20 ratio)
  • Never use full-strength ammonia
  • Avoid abrasive tools like scouring pads
  • Rinse surfaces thoroughly after cleaning
  • Limit ammonia use to occasional deep cleaning
  • Opt for gentler daily or weekly cleaning products

Cleaners like Method, Seventh Generation, and Mrs. Meyer’s have plant-based formulas that are safe for quartz. Using a mix of gentle cleaners and the occasional dilute ammonia solution is an effective approach.

Cleaning Tips for Quartz Countertops

To keep quartz counters spotless, follow these expert care recommendations:

  • Blot up spills immediately to prevent stains
  • Rinse surfaces after using ammonia cleaner
  • Use trivets and cutting boards to protect quartz
  • Avoid exposes to strong chemicals like paint removers
  • Don’t use scratched or abrasive cleaning pads
  • Reseal quartz annually with a stone sealer
  • Remove stuck-on food with soft cloth and warm water
  • Clean quartz regularly with pH-neutral stone cleaner

Signs of Quartz Countertop Damage to Watch For

Be alert for the following signs of etching or damage:

  • Visible dull spots or swirls
  • Foggy looking areas
  • Noticeable scratches or cuts
  • Permanent stains despite cleaning attempts
  • Changes in gloss level across the surface

When to Call a Professional

If your quartz countertops become damaged despite your best care efforts, contact a professional for repair. Quartz repair technicians have experience with resurfacing etched or damaged areas. They can also professionally re-polish and reseal your countertops.

For deep scratches, chips, or irreparable staining, a countertop replacement may ultimately be needed. But minor etching or fading can often be improved with professional restoration services.

The Bottom Line

Diluted ammonia can be used occasionally on quartz countertops to clean and disinfect. But improper use or overuse creates a risk of long-term damage. Limit ammonia to periodic use only after testing, at a 1:20 maximum dilution with water. Daily or weekly cleaning is best done with gentler cleaners made for stone. Follow manufacturer guidelines and treat quartz counters with care to preserve their flawless beauty. With the right gentle products and cleaning methods, quartz countertops will shine for years.
