How to Clean Grout in Floor Tiles

Grout serves as a fundamental part of floor tiling. Acting as the adhesive and filler between tiles, it ensures stability and alignment. Despite its utilitarian nature, grout can also be an aesthetic choice, complementing or contrasting with the tiles to enhance the overall appearance of a space. However, grout’s porous nature makes it prone to staining and discolouration, especially in areas with heavy foot traffic or exposure to moisture. Proper care and maintenance are essential to keep grout looking its best. Here’s a comprehensive guide to cleaning grout in floor tiles, encompassing all aspects of care, from daily maintenance to deep cleaning.

Understanding the Grout Type

Grout used in floor tiling comes mainly in two types: sanded and unsanded. Identifying the type is the first step in determining the appropriate cleaning method.

  1. Sanded Grout: Commonly used in floor tiling, sanded grout contains fine sand particles and is generally more robust and resistant to shrinkage. Its texture, however, can make it more susceptible to staining.
  2. Unsanded Grout: This type is smoother and often used in walls or for tiles closely spaced. Its texture makes it easier to clean but requires gentler handling to avoid damage.

Daily and Weekly Maintenance for Grout Cleaning

Regular maintenance is key to preventing deep-set stains and keeping the grout looking fresh.

  1. Daily Wiping: In areas like kitchens or bathrooms, wiping the tiles and grout with a damp cloth daily can prevent stain buildup.
  2. Weekly Cleaning: A mild detergent mixed with warm water can be used for weekly cleaning. A soft brush can be used to scrub the grout gently. Ensure thorough rinsing to remove any soap residue.

Deep Cleaning Methods for Floor Tiling Grout

Despite regular cleaning, grout may require deep cleaning from time to time, especially in high-traffic areas. Here’s a detailed guide to deep cleaning methods:

  1. Using Specialized Grout Cleaners: Several over-the-counter grout cleaners are designed specifically for deep cleaning. Follow the manufacturer’s instructions, and always test a small hidden area first.
  2. Natural Cleaning Solutions: A mixture of baking soda and water can create a paste that’s effective for cleaning grout. Apply the paste, let it sit for a few minutes, and then scrub with a soft brush. Vinegar can also be used but should be avoided with natural stone tiles.
  3. Steam Cleaning: Professional Floor Tilers Melbourne often recommend steam cleaning for stubborn stains. The intense heat and pressure from steam can dislodge grime without damaging the grout.
  4. Hire Professional Floor Tiling Services: For extensive grout cleaning or restoration, professional floor Tiling services in Melbourne offer specialized treatments that can bring grout back to its original appearance.

Sealing the Grout for Longer Durability

  1. Choosing the Right Sealer: Sealers come in various forms, some offering a glossy finish and others a matte appearance. Selecting the right one depends on the desired look and the type of grout used.
  2. Proper Application: Follow the manufacturer’s guidelines for application. Typically, the grout must be completely clean and dry before sealing. A small brush or applicator ensures precise application.
  3. Frequency of Sealing: Depending on the location and the type of sealer used, re-sealing might be required every one to three years.

Preventing Future Grout Discolouration

  1. Avoid Harsh Chemicals: Bleach or other harsh chemicals can break down the grout over time. Stick to mild detergents or specialized grout cleaners.
  2. Promptly Clean Spills: In areas prone to spills, such as kitchens, prompt cleaning can prevent stains from setting into the grout.
  3. Use Entry Mats: In entryways, mats can trap dirt and moisture, reducing the grime that gets into the grout lines.


Grout cleaning is an integral part of maintaining the appearance and integrity of floor tiling. Understanding the type of grout, employing regular cleaning routines, and opting for deep cleaning when necessary are key to keeping grout looking its best. Floor Tilers Melbourne professionals often emphasize the importance of appropriate cleaning methods and the possible use of sealers to prolong the life and appearance of grout. By following these guidelines, anyone can keep the grout in their floor tiling looking as impeccable as the day it was laid.
