How to Clean Terrazzo Floors: Best Way to Clean Terrazzo Floors in Commercial Settings

Terrazzo is one of the longest-lasting commercial flooring options on the market. Only if you give it the care it deserves, though. The wrong cleaner eats through the binder. Skipped sealing lets stains set permanently. Grit grinds the polish down underfoot. We’ll show you how to clean terrazzo floors correctly, because this is what separates a 75-year floor from one that looks worn in 5. 

The key takeaway: facilities maintaining large terrazzo areas need a commercial floor scrubber for better results in a fraction of the time manual mopping takes. SweepScrub carries everything from massive ride-on models to compact walk-behind units, always sourced from the best brands.

The Best Way to Clean Terrazzo Floors in Commercial Settings

The best way to clean terrazzo floors comes down to three things: the right tools, the right chemicals, and a consistent schedule. Here's what to use to clean terrazzo floors and which tools make the biggest difference.

Mops and Pushbrooms

Pushbrooms scatter particles back onto the surface, which ultimately defeats the purpose of polished terrazzo. A flat microfiber mop with pH-neutral cleaner handles the wet step in corridors and small rooms. 

This is how to clean terrazzo floors yourself on a budget - minimal equipment, just some good ol’ fashioned labor. But manual tools can't keep up once you're cleaning terrazzo floors across an entire school wing or hospital floor.

Sweepers and Scrubbers

A commercial floor sweeper machine replaces the dust mop at scale, capturing grit across wide cleaning paths without grinding particles into the terrazzo. Meanwhile, a floor scrubber lays down solution, scrubs, and vacuums dirty water in one pass - no haze from mop water drying on the floor. 

Want to consolidate cleaning equipment and work smarter? A floor sweeper scrubber machine combines both passes into a single trip. The best way to clean terrazzo floors in any space over a few thousand square feet involves one of these machines.

What Chemicals Are Safe for Terrazzo Flooring?

pH-neutral cleaners are a non-negotiable. Cementitious terrazzo dissolves on contact with acid. Even mild acids like vinegar cause damage that shows up in the form of dull patches, pitting, and weakened joints. 

Epoxy terrazzo is more chemical-resistant but still performs best with neutral formulas. Our advice on what to use to clean terrazzo floors in heavy-traffic commercial settings is a mild alkaline cleaner (pH 8-10). It will handle scuffs and heavier soil without risking the binder. 

Start with a commercial neutral floor cleaner at the manufacturer's dilution if you're figuring out how to clean terrazzo floors yourself. It’s the safest baseline for both terrazzo types.

How Do You Clean Terrazzo Floors? Step-by-Step Guide to Cleaning Terrazzo Floors

Cleaning terrazzo floors breaks into three tiers - daily, deep, and semi-annual. Each has a very specific purpose and process. But before we can even get into how to clean terrazzo floors, we need to figure out exactly what you’re working with.

First Things First, What Terrazzo System Do You Have?

We see two main types of terrazzo floors in commercial settings:

• Cementitious terrazzo uses a cement binder. It's porous, absorbs moisture, and needs a sealer for stain protection. 
• Epoxy terrazzo uses resin. It’s denser, less porous, and more forgiving with chemicals and water exposure.

The best way to clean terrazzo floors depends on which system you have. Like we touched on earlier, cementitious demands stricter chemical discipline and more frequent resealing.

Daily Maintenance for Terrazzo Floors

Sweep the full surface first, every time. Grit can kill terrazzo's polish as foot traffic grinds loose particles into the finish, creating micro-scratches that build into visible dullness over weeks. Then, you can put your floor scrubber to use with a pH-neutral cleaner at the manufacturer's dilution. 

Don't flood cementitious terrazzo. Excess water seeps into pores and undermines the sealer. No need to worry about that if you use a floor scrubber, since it controls moisture. Mopping is more prone to user error.

This daily routine is how to clean terrazzo floors yourself without professional help. You just need a sweeper, neutral cleaner, and floor scrubber. Knowing what to use to clean terrazzo floors at this stage keeps it simple - but you’ll need the best tile floor cleaning machine for sure.

Polishing Your Terrazzo Flooring

How to clean and polish terrazzo floors is two separate processes. Cleaning removes soil. Polishing restores gloss. This step is just as important for preserving your floor's stunning luster.

Diamond polishing pads on a floor machine progress through coarse to fine grits until the surface hits the desired shine. No chemicals needed - just water and pad progression. Polishing every 6-12 months keeps that reflective finish looking its best without a full strip-and-reseal.

However, stripping and resealing is something you’ll need to make time for occasionally…

Semi-Annual Maintenance (Stripping and Resealing)

Cementitious terrazzo with floor finish needs periodic stripping and recoating. Remove the old finish with a commercial floor stripper (alkaline - never acid), clean and rinse the bare surface, then apply fresh sealer. This restores stain and moisture protection. 

You can skip this step if you have epoxy terrazzo. Polishing alone keeps the surface pristine. Cleaning terrazzo floors gets easier after a fresh seal because the pores are closed and soil sits on top instead of absorbing.

Dos and Don'ts of Terrazzo Floors Cleaning

Few more pieces of advice we want to offer (and some words of caution) regarding terrazzo floors cleaning:

DO

• Dust mop or sweep daily - grit destroys the polish faster than anything else
• Stick to pH-neutral cleaners for every routine cleaning
• Rinse after scrubbing to avoid chemical residue dulling the finish
• Reseal cementitious terrazzo on schedule (unsealed pores absorb stains permanently)
• Place walk-off mats at entrances to catch sand and grit before it hits the floor
• Wipe spills immediately - water alone can stain unsealed cementitious terrazzo

DON'T

• Use vinegar, citrus, or any acid-based cleaner because they dissolve the cement binder
• Scrub with black or brown pads - they’re too aggressive for polished terrazzo
• Let dirty mop water air-dry on the surface as it leaves haze and redeposits soil
• Apply oil-based or wax-based products. They yellow and attract dirt
• Skip the dry sweep before wet cleaning (wet grit scratches worse)
