Granite Cleaning, Polishing & Sealing in San Diego

Cleaning, polishing, restoration, disinfection and sealing for granite countertops, floors and showers in homes and businesses, with maintenance advice to protect your investment.

Quick answer

How Is Granite Cleaned and Protected?

Granite is hard and quartz-based, so acidic foods and cleaners do not etch it the way they etch marble. Clean it with warm water or a stone cleaner and dry it after use, have stains and water marks treated professionally, and keep it sealed with a penetrating, food-safe sealer. Dull granite needs professional polishing; never use wax or surface enhancers.

Why it matters

Why Granite Still Needs Care

Granite adds value wherever it is installed, thanks to its strength and good looks. It is hard to scratch and resists acids, so it is easy to maintain day to day.

Professional help is worth it for stains, water marks or a sealer that was poorly applied in the past, because the wrong product can damage the stone. We provide stone care services and advice on the steps you can take yourself.

About the material

What Makes Granite Different From Marble?

Granite is a hard, quartz-based stone rather than a calcium-based one. That is why it shrugs off the acidic spills that etch marble, and why its care is mostly about stains, water marks and keeping the sealer working.

Quartz-based

Made of quartz rather than calcium, so acidic foods and cleaners do not etch it the way they etch marble.

Very hard

One of the hardest stones used in homes, so it is difficult to scratch.

Still porous

Its pores can absorb wine or oil and trap stains; even resin-impregnated granite can stain.

Polished finish

A dull finish is restored by professional polishing, never by wax or surface enhancers.

Sealing granite

Does Granite Need Sealing?

Yes. Like all natural stone, granite has pores that can absorb spills such as wine or oil and trap stains. Even resin-impregnated granite can still stain, so a good sealer is recommended.

Choose a penetrating sealer rather than a topical one. Penetrating sealers protect inside the pores; topical products sit on the surface, can be damaged by acids and chemicals and may leave a cloudy look. On countertops, use a non-toxic, food-safe sealer.

The water test: most granite needs resealing every one to two years, but rather than going by the calendar, sprinkle some water on the stone. If it beads up, the sealer is still working. If it soaks in quickly, it is time to reseal.

Compare the options

Cleaning, Polishing or Restoration?

Most granite only needs cleaning and a working sealer. Polishing and restoration are for finishes that have gone dull or been damaged.

What to avoid

What to Avoid on Granite

Granite is tough, but a few common products shorten the life of its finish and sealer.

  • Wax or surface enhancers to add shine; dull granite needs polishing
  • Harsh or abrasive cleaners
  • Topical sealers, which acids and chemicals can damage and which can look cloudy
  • Sealers that are not food-safe on kitchen countertops
  • Leaving grit on floors, which wears the finish in high-traffic areas

Common questions

Frequently Asked Questions

How should I clean granite day to day?

Clean frequently used granite with warm water and dry it afterward, or use a cleaner made for natural stone about once a week. Avoid harsh cleaners.

Does granite need sealing?

Yes. Granite has pores that can absorb spills and stain. A penetrating sealer is recommended, and a food-safe one on countertops.

How often should granite be resealed?

Usually every one to two years. Test it: if water beads on the surface the sealer is working; if it soaks in quickly, reseal.

How often does granite need polishing?

It depends on use and care. High-traffic areas, or places where grit is not cleaned up quickly, wear faster.

How much does granite care cost?

It depends on what the stone needs. Call (858) 952-0777 for a free quote.

Can acidic foods damage granite?

Granite is quartz-based rather than calcium-based, so acidic foods and cleaners do not etch it the way they etch marble. Acidic cleaners can still break down the sealer over time, so use a stone cleaner.

Can I wax granite to bring back the shine?

No. Wax and surface enhancers should never be used on granite. A dull finish needs professional polishing to the level the stone requires.
