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

Porcelain tile is incredibly common in commercial facilities. We see it in lobbies, restrooms, kitchens, retail spaces, healthcare corridors, and countless other buildings. It’s easy to see why - it holds up well under heavy foot traffic, and looks stunning when clean. 

That’s why maintenance is so important, though. Cleaning porcelain floors the right way on a regular basis maximizes the benefits of this material. Otherwise, dirt builds up in the texture and grout lines trap grime. The wrong cleaning method can leave haze or damage the finish over time. 

Knowing how to clean porcelain floors involves meticulously picking chemicals, sourcing the right equipment, and implementing the optimal process to keep the surface looking professional and extend its lifespan. We’ll walk you through the best way to clean porcelain floors below.

Key Takeaways on Cleaning Porcelain Floors

• The best way to clean porcelain tile floors is a two-step process: dry sweep to remove loose debris, then scrub with a pH-neutral cleaner.
• Avoid acidic cleaners, bleach, and abrasive pads on glazed porcelain. These dull the finish and damage grout.
• Porcelain itself resists staining, but grout absorbs dirt and moisture if it's not sealed and maintained. Grout needs separate attention.
• A commercial floor scrubber, sweeper, or sweeper-scrubber can cut cleaning porcelain tile floors from an hour-long manual job down to minutes. 
• SweepScrub has the cleaning equipment and chemicals you need to elevate your porcelain floors cleaning process. Get in touch for one-on-one support. 

What to Use to Clean Porcelain Tile Floors

Our advice on what to use to clean porcelain tile floors depends on the type of porcelain (glazed vs unglazed), the kind of soil, and how large the area is. We’ll walk you through the essentials below.

Safe Chemicals

pH-neutral floor cleaners are the standard for porcelain in commercial settings. They lift dirt without attacking the glaze or degrading grout. Look for products specifically labeled for hard tile floors. Most commercial neutral cleaners from brands like Betco, Diversey, or our own KleenLine work well. 

A mild alkaline cleaner (pH 8-10) can handle grease and scuff marks without crossing into damage territory. Whatever you do, avoid anything marketed as a “heavy-duty degreaser” or “acid cleaner” if you're looking for the best cleaning product for porcelain tile floors in a commercial environment.

The one exception is if you're dealing with unglazed porcelain and know exactly what you're applying. Glazed porcelain has a protective layer that aggressive chemicals strip over repeated use.

DIY Solutions

Maybe you’re wondering what to use to clean porcelain floors when you don’t have access to professionally formulated chemicals. 

• A simple mix of warm water and a few drops of dish soap works for spot cleaning or smaller commercial spaces. 
• White vinegar diluted in water handles light mineral deposits and haze, but use it sparingly since vinegar is acidic and will erode grout with repeated application. 
• Baking soda paste works for individual stains on the tile surface, too. 

All of these are last resorts, not your go-to for daily maintenance. Facilities cleaning porcelain tile floors across thousands of square feet should invest in the right chemicals, which we talked about above.

Floor Sweepers/Scrubbers

As for what to use to clean porcelain floors from an equipment perspective, you have options. Not all of them are good. A mop spreads dirty water around. It makes less and less sense the larger your facility is. It’s worth elevating your janitorial arsenal with a sweeper, a scrubber, or both!

A commercial floor sweeper machine handles the dry debris (dust, grit, loose dirt) without pushing particles into grout lines the way a broom does. Then you can use a floor scrubber to apply cleaning solution through a brush or pad, scrub the surface, and vacuum up the dirty water in a single pass. 

Facilities that want both steps in one machine can upgrade to a floor sweeper scrubber machine. These sweep and scrub at once, cutting cleaning time in half. 

The difference in outcome and efficiency is significant. Mops leave dirty water sitting on the tile until it air-dries, which can lead to haze and redeposits soil into grout. Scrubbers extract the water immediately, so the floor dries clean. 

SweepScrub carries all types of floor cleaning machines from the most trusted brands the industry has to offer. From massive ride-on units to compact walk-behind models for tight spaces, we’ll help you pick the right solution for YOUR business.

Now that you know what to use to clean porcelain floors, let’s get into the actual process - here’s how to clean porcelain floors in your building. 

How to Clean Porcelain Floors in Commercial Settings: Step-by-Step Guide

The best way to clean porcelain tile floors looks the same whether you're maintaining a 500-square-foot retail shop or a 50,000-square-foot warehouse. The tools scale to the space, but the process stays the same. Here’s how to clean porcelain tile floors:

Step 1: Clear Loose Debris

Start with a dry pass. Sweep or vacuum all loose dirt, dust, sand, and grit off the surface. Otherwise, you could end up grinding that grit into the tile and grout during the wet cleaning step, causing micro-scratches on glazed porcelain and pushing dirt deeper into grout lines. 

A floor sweeper handles this faster and more thoroughly than a push broom in commercial settings, especially on textured porcelain where particles settle into the surface grain. It’s well worth the investment.

Step 2: Pre-Treat Problem Areas

Stains, scuff marks, and heavily soiled grout lines need direct attention before the full floor scrub. Apply your cleaning solution directly to the spot and let it sit for 3-5 minutes. 

Grout lines in high-traffic zones usually need a stiff nylon brush and a little stronger concentration. Don't skip this. A single-pass scrub won't pull deep-set stains out of grout without pre-treatment.

Step 3: Apply Cleaning Solution and Scrub

Mix your pH-neutral cleaner at the manufacturer's recommended dilution. The scrubber's solution tank handles distribution automatically, so there’s no need to worry about flooding the floor or not putting down enough solution.

Porcelain responds well to cylindrical brush scrubbers and red or blue floor pads, depending on soil level. Red pads for daily maintenance on lightly soiled floors. Blue pads for heavier cleaning. You’ll want both in your porcelain floors cleaning arsenal.

Avoid black pads on glazed porcelain, as they're too aggressive. Our breakdown of the best tile floor cleaning machine options covers which scrubbers pair best with hard tile surfaces.

Step 4: Rinse the Surface

Cleaning solution left on porcelain dries into a haze - that dull film you see on tile floors that were mopped but never rinsed. You may need a full bucket change and a separate rinse pass if you’re using a mop.

Fortunately, floor scrubbers make this automatic, so you don’t have to spend too much extra time on it. Dump the dirty recovery tank, refill the solution tank with clean water, and run a second pass. That’s the key takeaway from our guide on how to clean porcelain floors: work smarter, not harder. 

Step 5: Dry Thoroughly

Standing water on porcelain creates slip hazards and leaves mineral deposits as it evaporates, especially in facilities with hard water. Again, this is a non-issue with floor scrubbers since they extract most of the water during operation, leaving the floor completely dry behind the machine. 

On the other hand, you’ll need to use a wet-dry vacuum to pull remaining water off the surface if you're mopping, or at the very least, put out wet floor signs. High-traffic areas should be fully dry before reopening to foot traffic.

What About the Grout?

Porcelain tile itself is nearly impervious to staining since it's fired at extremely high temperatures and has very low porosity. Not the case for grout, though. It’s actually the opposite - porous, absorbent, and collects every drop of moisture, dirt, and cleaning chemical that reaches it. 

In fact, most of what people call “dirty porcelain floors” is actually dirty grout making the whole floor look worn. That’s why figuring out how to deep clean porcelain tile floors starts with the grout. 

Use a pH-neutral or mildly alkaline cleaner with a stiff brush on grout lines, working in small sections. An oxygen bleach solution (sodium percarbonate mixed with warm water) lifts embedded dirt without the harshness of chlorine bleach for severe buildup. Rinse thoroughly after treatment.

Seal the grout once it’s clean, or you’ll just be back to square one within days. A penetrating grout sealer fills the pores and makes future cleaning way easier. One of the best things you can do to maintain your porcelain floor. Reapply annually or as recommended by the sealer manufacturer.

What Should You NOT Clean Porcelain With?

Porcelain is hard to damage, but the wrong products do it gradually. It’s usually too late to reverse by the time the damage is visible. We walked about how to clean porcelain floors, but now let’s cover what NOT to do:

• Acidic cleaners: Vinegar, citrus-based products, and acid-based tile cleaners erode grout with repeated use and can dull glazed porcelain over time. A one-time spot treatment is fine. Daily use is not.
• Chlorine bleach: Discolors colored grout and weakens the grout structure over time. Oxygen bleach is the safer alternative for deep cleaning.
• Abrasive pads and steel wool: Scratch glazed porcelain permanently. Stick to nylon brushes and non-abrasive floor pads.
• Oil-based cleaners: Leave a film on porcelain that attracts more dirt and creates slip hazards. Porcelain needs water-based cleaning products.
• Ammonia at full strength: Safe when diluted, but undiluted ammonia can damage grout and leave a residual odor that lingers in enclosed commercial spaces.

But whether you’re looking for the right chemicals or trying to choose the best floor scrubber for vinyl, best floor scrubber for laminate, or anything in between, there’s no need to figure it out on your own. You can connect with our experts at SweepScrub for one-on-one support.
