How to Keep Grout Clean Longer (And Why Your Grout Gets Dirty So Fast)

The 5 Real Reasons Your Grout Gets Dirty Fast

1. Grout Is Naturally Porous

Grout is like a sponge. It has tiny pores that absorb dirt, liquids, grease, and even cleaning products. Every time you mop your floor, you’re likely pushing dirty water into those pores unless you’re using the correct method and eliminating puddling. 

Pro Tip: Even if your tile is clean, the grout lines can trap grime and cause your floors to look dingy. Vacuuming is a great way to remove loose soils without pushing them into the grout.

2. Using the Wrong Cleaning Products

Acidic or harsh cleaners (like vinegar, bleach, or ammonia) can actually break down grout and protective sealers. This makes it easier for grime to penetrate deep into the surface. If these cleaners are not thoroughly rinsed after cleaning they will continue to eat away at your grout causing pin holes and weakening the bond of the grout. These pin holes and cracks can act as highways for dirt and grime to get deep within the grout and cause discoloration. 

Pro tip: Stick to a pH-neutral floor cleaner, especially for natural stone and grout. Acidic cleaners such as many grout cleaners from big box stores can damage natural stone floors like marble, travertine and limestone.

3. Improper Mopping Technique

Many homeowners use too much water or don’t change the mop water often enough. When water is allowed to puddle it grabs the dirt off the large part of the floor, being the tile, and pushes it into the grout lines where it is soaked up like a sponge. Even if the grout is sealed water will still find its way past the sealer if it sits long enough and you can bet it will carry any dirt it can find with it. Also if you do not change the water often when mopping or change out the mop heads/pads, you end up pushing the dirt from one place to the other.

Pro Tip: How you clean your floors is actually more important than how often you clean your floors. We recommend using a spray bottle of neutral cleaner and misting the floor then buffing the floor dry with a microfiber mop. You can see a demonstration if you check out our tile and grout cleaning care guide.

4. Your Grout Has No Seal or an Old One

If your grout was never sealed (or the sealer has worn off), it has no defense against daily wear and moisture. This is one of the biggest reasons grout stains so quickly—especially in kitchens, bathrooms, and entryways. We recommend sealing grout every 1-3 years depending on foot traffic and how often you have your floors professionally cleaned. Color seal on the other hand is a strong durable sealer that forms a topical barrier on the grout making it essentially non-porous. Color seal will last much longer and provide the homeowner with more effective “daily” cleanings and professional cleanings.

Pro Tip: If you select to have your floors color sealed by Beyond Clean Tile and have your floors professionally cleaned by us within 3 years of application we will touch up and color seal for FREE and extend the offer for another 3 years. This could go on for a life time saving you lots of money while also providing you the best results possible. 

5. Heavy Foot Traffic

High-traffic areas like hallways, kitchen floors, and entryways naturally collect more grime. If you are not taking measures to slow down the amount of dirt your floors are exposed to then rapid soiling can occur. Shoes track in dirt, oils, and fine grit that wears down grout sealants and pushes debris into the pores. Door mats and walk off rugs can hold dirt and cause it to spread throughout the house if they are not regularly cleaned. Oily garage floors can easily transfer dirt and oils to your shoes and into the house if not kept clean. Paying attention and keeping the exterior of your entry points to your house can have a difference. 

Pro Tip: If your entryway grout is darker than the edges of the room, traffic is the likely culprit.

How to Keep Grout Cleaner for Longer

• ✔️ Clean with a microfiber mop that lifts the dirt instead of pushing it around
• ✔️ Mist the floor instead of wet mopping
• ✔️ Use walk-off mats at all entrances
• ✔️ Seal your grout after professional cleaning to prevent fast re-soiling
