How to Deep Clean Grout Like a Pro with Tile & Grout Cleaning Machines
Grout: it’s the space between tiles that most people forget… until it’s stained, discoloured, and dragging down the look of your entire floor or wall. If you’ve ever tried scrubbing grout lines with a toothbrush, you already know: that it’s time-consuming, backbreaking, and honestly, not that effective.
But here’s the thing with the right tile & grout cleaning machine, you don’t have to spend hours on your knees. You can bring back that clean, fresh-from-the-showroom tile shine in half the time, and with much better results.
Whether you’re a professional cleaner, a facility manager, or just a homeowner sick of dingy grout lines, this guide walks you through the process step-by-step.
Why Grout Gets So Dirty — And Why Manual Cleaning Isn’t Enough
Grout is porous. That means it absorbs dirt, moisture, soap scum, and whatever your shoes drag in and hold onto it. Over time, this grime builds up, causing staining, mould, and odours.
While DIY methods like baking soda and vinegar might help a bit, they rarely penetrate deep enough. That’s where a tile & grout cleaning machine changes the game. These machines use rotating brushes, high-pressure water, and vacuum suction to lift grime from deep inside grout lines, not just off the surface.
Step-by-Step: How to Deep Clean Grout the Right Way
1. Choose the Right Equipment for the Job
Before you plug anything in, you need to make sure you’re working with the right tool. There’s a huge difference between basic consumer tools and an industrial tile and grout cleaning machine especially if you’re cleaning large areas like commercial kitchens, lobbies, or restrooms.
For a wide range of machines (from portable residential models to heavy-duty commercial units), we recommend Clean Care. Their lineup of tile and grout cleaning equipment for sale includes models for every use case, with reliable performance and professional-grade results.
Look for these key features:
- Adjustable pressure and water temperature
- Interchangeable brushes for different surfaces
- Strong suction for quick drying
- Easy maneuverability
2. Prep the Area
Clear the space. Remove any furniture, rugs, or obstructions. Vacuum or sweep the floor to get rid of loose dirt. This might seem like an extra step, but it prevents the machine from grinding debris deeper into the grout.
3. Apply Cleaning Solution
Most machines work best with a compatible grout cleaner. Avoid acidic or bleach-based products unless the manufacturer says otherwise. Apply the solution evenly and let it dwell for 5–10 minutes — this allows the chemicals to break down grease and grime, making it easier to lift.
4. Scrub and Extract
Now the fun part. Fire up your tile & grout cleaning machine and let it do the heavy lifting. The brushes scrub the grout while the high-pressure water lifts dirt. Simultaneously, the suction function removes dirty water, leaving the surface clean and nearly dry.
If you’re using a machine from Clean Care, many models allow you to adjust brush pressure and water output based on the tile type, which is perfect for avoiding damage on delicate surfaces.
5. Rinse (Optional) and Dry
Once you’ve cleaned the entire area, a clean-water rinse will remove any leftover residue. Use the suction mode to pick up the rinse water. Then let the surface dry completely open windows, turn on fans, or just give it time.

Maintenance Tips for Lasting Clean Grout
- Seal the grout: After a deep clean, sealing the grout lines helps protect them from future staining.
- Clean regularly: Use a smaller handheld or portable machine for touch-ups, especially in high-traffic areas.
- Spot clean spills quickly: The faster you respond, the less chance of permanent staining or mildew buildup.
