Commercial Grout Cleaning: What Do Professionals Use to Clean Grout?

Grout starts out light and uniform, but it doesn’t stay that way long unless you invest in regular commercial grout cleaning. All it takes is a few months of foot traffic in a commercial facility before it looks dark, stained, and neglected - even if the tile itself is clean. 

Mopping won't fix it once the staining sets in. The best ways to clean grout in a commercial setting require the right chemical, the right machine, and a schedule that stays ahead of the problem. 

So, what do professionals use to clean grout? They turn to SweepScrub for a commercial floor scrubber, attachments, and cleaning chemicals to simplify grout maintenance.

Why Commercial Grout Cleaning is Worth Investing in

Floor appearance directly affects business in countless industries: restaurants, retail, hospitals, schools - the list goes on and on. Stained grout lines tell customers the place isn't maintained, even if the tile is spotless.

The problem is that grout is porous, so it absorbs whatever hits it - dirt, grease, food spills, cleaning residue, and moisture. That absorption is constantly happening in high-traffic commercial settings. 

It’s so frustrating. The tile surface wipes clean because it's glazed and non-porous. The grout lines don't, because they sit recessed below the tile plane where mops and flat scrub pads can't reach.

That’s the problem. The discoloration you see with stained grout is embedded in the material. Getting it back to the way it used to look means combining agitation with a chemical that breaks soil loose from inside the porous surface. 

How Often to Make Time for Commercial Grout Cleaning?

There’s no one-size-fits-all answer on how often you need to clean your grout lines. It all depends on foot traffic and what's hitting the floor. 

Restaurants and food service kitchens need monthly deep cleans since grease doesn't sit on grout the way it sits on tile. It soaks in, and a mop pass won't pull it back out. 

On the other hand, offices and retail spaces with lighter traffic and no food or biological contamination can stretch to quarterly as long as they're regularly scrubbing the floor itself.

Whether you’re involved in hospital floor cleaning or school floor cleaning, the smart approach is to err on the side of more frequent than not frequent enough. 

How to Clean Grout in Commercial Settings: What Do Professionals Use to Clean Grout?

The best ways to clean grout in a commercial setting involve machines rather than manual labor. Don’t get us wrong, we can appreciate some good ol’ fashioned elbow grease. But grout is unique, and it’s always better to work smarter instead of harder.

So, what do professionals use to clean grout? You need the right chemical paired with a powerful machine, and then the right strategy. We’ll cover it all below. 

Choose the Right Cleaning Solution

The best commercial grout cleaner for most commercial tile floors is an alkaline degreaser with a pH between 10 and 13. This will effortlessly break down grease, oils, and organic soils - the most common culprits behind grout discoloration in restaurants, kitchens, and high-traffic areas. 

Apply the solution and let it dwell on the grout for 5-10 minutes before scrubbing. That dwell time lets the chemical penetrate the porous surface and loosen embedded soil before the brush hits it.

Whatever you do, avoid acidic cleaners on cement-based grout since they can dissolve cement. Vinegar, muriatic acid, and low-pH tile cleaners eat into the grout surface. They leave behind pitting and make the material more porous, so the grout stains faster going forward. 

Is your grout stained by rust, hard water deposits, or mineral buildup specifically? A mildly acidic product may help in this case, but take care to test a small area first and never let it sit on cement-based grout. 

Invest in a Commercial Grout Cleaning Machine

A commercial grout cleaning machine covers large floor areas, consistently applying enough down pressure to pull embedded soil out of grout lines. This is the smartest investment you can make in your commercial floor care arsenal.

The key is using a brush, not a pad. Flat scrub pads ride across the tile surface and completely skip over the recessed grout lines. A brush with stiff bristles reaches into those grooves.

You’ll also want to clear loose debris off the floor before running the scrub pass. Grit under the brush scratches tile. A commercial floor sweeper machine handles this faster than a broom without spreading dust in the air. 

A floor sweeper scrubber handles dry debris and the grout scrub in a single pass, saving time and consolidating your equipment closet. Otherwise, a commercial walk-behind floor scrubber with a brush attachment is what most facilities use for routine grout maintenance. 

The machine lays down cleaning solution, the brush agitates the grout lines, and the squeegee vacuums up the dirty water all in a single pass, leaving the floor clean and dry. 

You might need a dedicated commercial grout cleaning machine with higher brush RPM and more down pressure than a standard scrubber delivers for deep restoration where grout has years of embedded staining.

What do professionals use to clean grout on large floors? The same commercial floor scrubber they use for everything else, just with the right brush installed and the right chemical in the tank. One machine handles grout days and regular cleaning days. 

Spotlight on the Sandia Sniper 80-5000

This machine is a little different than your typical floor scrubber. It doesn’t use brushes at all. It blasts grout lines with 1,200 PSI through a 12” spinner tool. It’s way more aggressive than any scrubber brush can manage. Dual Lamb Ametek motors pull 170 inches of water lift, recovering dirty water on contact so soil doesn't settle back into the grout. 

The pro package includes the spinner tool, a handheld tool for edges and corners, plus degreaser and grout/tile renewer. 12-gallon solution and recovery tanks with auto-fill and auto-dump lines keep you running without stops.

It’s by far the best way to clean grout in commercial settings, and you’ll see why once you put it to use in your own facility. Get in touch today to learn more and start working smarter!

Does Steam Cleaning Work Well Enough?

Steam cleans grout without chemicals, using heat and pressure to loosen embedded soil so you can wipe or vacuum it away. This approach can definitely work for small areas and spot treatment. But is it the BEST grout cleaning method at scale? No. 

It just comes down to practicality. A handheld unit covers a few square feet at a time. A commercial tile floor has hundreds or thousands of square feet of grout lines.

Steam doesn't handle grease-based staining as well as an alkaline degreaser, either. The heat loosens some of it, but there’s no chemical agent breaking the bond between grease and grout. The soil returns faster after steam cleaning than after a proper chemical-and-brush scrub. 

Spot Cleaning Tight Spaces

Floor scrubbers handle open floor areas, but even compact walk-behind models can’t reach corners, edges along walls, under counters, or inside door frames. You’ll need a stiff nylon grout brush for those spots. Pair it with the same alkaline solution. 

You see, the best ways to clean grout in tight spaces haven't changed just because you’re working in tighter quarters. It’s still a process of chemical, agitation, and extraction, just without the machine. A wet/dry vacuum helps pull the dirty solution from corners and edges after scrubbing. 

That’s a key takeaway from commercial grout cleaning - don't let anything dry on the surface. That redeposits the soil you loosened. You’ll need to suck the mess up somehow.

Frequently Asked Questions

Is professional grout cleaning worth it?

Yes, if your grout is visibly stained and mopping doesn't fix it. The best ways to clean grout use the right chemical to break soil loose and a stiff brush to pull it out of the pores, and regular machine maintenance after the initial deep clean prevents the buildup from coming back.

What do professionals use to clean grout?

An alkaline degreasing solution (pH 10-13) paired with a floor scrubber running a stiff brush attachment. The chemical breaks soil loose, the brush agitates it out of the grout lines, and the squeegee picks up the dirty water. The best commercial grout cleaner is almost always alkaline.

How do you clean severely dirty grout?

Start by applying a strong alkaline degreaser and letting it dwell for 10-15 minutes. Run a floor scrubber with a stiff brush. You may need multiple passes on heavily stained sections. A commercial grout cleaning machine with higher RPM and down pressure helps if the grout doesn't respond.
