1. Scouring Powder, Hot Water, and a Stiff Brush
One of the most common and straightforward ways to clean grout is with a scouring powder, hot water, and a stiff-bristle brush.
This method is ideal for small areas of grout with light staining, especially if your floor is relatively new. How hard you scrub will depend on the level of staining but be careful not to apply too much pressure, as this can damage the tiles.
- Scouring powder
- Hot water
- Stiff-bristled brush (a grout brush or durable cleaning brush is perfect)
- Rubber gloves
- Protective goggles (optional)
- Step 1. Mix sourcing powder and water: Mix the scouring powder with the hot water in a bucket. Follow the manufacturer’s instructions on the correct scouring powder to water ratio. Stir it until it forms a paste.
- Step 2. Protect yourself: Put on your rubber gloves and goggles (if using) to protect yourself from the harsh chemicals (many scouring powders contain bleach or ammonia).
- Step 3. Apply the paste: Dip your brush into the paste, scooping up as much as you need to cover the bristles. Apply the paste to the grout lines, scrubbing in a back-and-forth motion, and scrub lightly at first to see how much pressure is required. If the stains are stubborn, you may need to scrub harder.
- Step 4. Small sections: Work in small sections until you’ve covered the entire area. Pay special attention to any areas that seem to be stained more than others. Check under furniture and in corners, as these areas are often neglected.
- Step 5. Rinse the area: Once you’ve finished scrubbing, leave the paste on for 10-15 minutes to allow it to work its magic. Then, rinse the area with clean water to remove all traces of the scouring powder. Use a clean cloth or sponge to wipe away any residual paste.
- Step 6. Let it dry: Allow the area to air-dry completely before walking on it or replacing furniture. You don’t want to track the scouring powder or water onto other areas of your home.
- Gentle pressure: Don’t use too much pressure when scrubbing, as this may scratch your tiles. Start with light pressure and increase as needed.
- Ventilation: Ventilate the area well while scrubbing and rinsing to avoid inhaling harmful fumes. Open windows and doors if possible.
- Only ceramic tiles: Only use this method on ceramic tile. Do not use it on natural stone or glass tile, as it can damage the surface.
2. White Vinegar and Water Solution
Whenever you need to clean something in your home, vinegar is likely the first thing that comes to mind. And for a good reason – vinegar is a powerful cleaning agent that can be used on various surfaces and does an amazing job cutting through grease and grime. But did you know that you can also use it to clean grout?
Vinegar contains acetic acid, a weak acid that breaks down stains and dirt. It’s also non-toxic and won’t harm your tile or grout as some harsh chemicals can. When using a vinegar solution to clean grout, do preliminary cleaning with a mild detergent to remove any surface dirt.
- White vinegar
- Spray bottle
- Liquid detergent (optional)
- Rubber gloves
- Soft-bristled brush
- Clean cloth or sponge
- Step 1. Mix vinegar and water: Mix 2-4 parts water with 1 part white vinegar in a bucket. Add 1/2 a teaspoonful of liquid detergent for extra cleaning power. Stir thoroughly for even mixing.
- Step 2. Use a spray bottle: Pour the mixture into a spray bottle. This makes applying the solution on the grout lines easy without over-wetting the tile. Fill the spray bottle to the top so you don’t have to stop and refill in the middle of cleaning.
- Step 3. Protect yourself: Put on rubber gloves to protect your hands from the acidic vinegar.
- Step 4. Apply the mixture: Spray the grout lines generously with the vinegar solution. Work in small sections, preferably 1 to 2 square feet at a time, ensuring that the grout is dampened. Leave the mixture to sit for 3 to 5 minutes.
- Step 5. Scrub the grout: Use a soft-bristled brush to scrub the grout lines. Work in small, circular motions to loosen the dirt and stains. Use a back-and-forth motion if the bristles are too long to scrub in a circle. Scrub until the grout is visibly clean.
- Step 6. Remove the mixture: Wipe away the dirty vinegar solution with a clean cloth or sponge. Wring it out frequently to avoid re-depositing the dirt onto the grout. Repeat steps 4 through 6 until all the grout lines are clean.
- Step 7. Rinse the area: Rinse the entire area with clean water to remove all traces of the vinegar solution, and use a clean cloth or sponge to wipe away any residual solution. Dry the area with an absorbent cloth or towel to prevent water spots and to speed up the drying process.
- Always dilute: Never use undiluted vinegar on grout. It can quickly eat away at the grout and could damage the tiles. Always use a diluted vinegar solution.
- Not for all materials: Never use vinegar on natural stone or marble. The acidity can etch the surface and damage it permanently.
- Do not scratch: If you’re using a brush with long bristles, be careful not to scratch your tile while scrubbing. Use a back-and-forth motion instead of scrubbing in circles.
- Gentle pressure: Avoid using excessive pressure when scrubbing, as this can damage the tiles. The strokes should be gentle but firm.
3. Hydrogen Peroxide and Baking Soda
Hydrogen peroxide is another cleaning agent you probably already have in your home. It’s a powerful natural oxidizer that can easily break down stains, and is often used as a natural alternative to bleach.
Combined with baking soda, it makes an effective cleaning paste that quickly cuts through grime and dirt. Baking soda is mildly abrasive, so it helps to loosen the dirt and grime from the surface. It’s also non-toxic and gentle, making it safe to use on tile and grout.
