To clean grout, start by sweeping, then apply a paste of baking soda and water (or peroxide/vinegar for tougher stains), let it sit, scrub with a brush (like an old toothbrush), and rinse thoroughly with warm water, ensuring all residue is gone to prevent haze. For tough mold or stains, commercial cleaners or oxygen bleach (OxyClean) can be used, but always ensure good ventilation and test on a small area first, and avoid mixing cleaners like bleach and vinegar.
You generally should not grout directly over old grout for longevity and adhesion, as it often leads to cracking and peeling; instead, you must first remove a significant portion (at least 2mm) of the old grout, thoroughly clean the area, and then apply the new grout to ensure proper bonding and a lasting finish. Special rejuvenation grouts or epoxy grouts might require less removal, but scraping out most of the old material is the best practice for standard grout.
To whiten grout, use a paste of baking soda and water/hydrogen peroxide, scrub with a stiff brush, let it sit, then rinse; for tougher stains, try a vinegar/baking soda mix or a bleach/baking soda paste, always rinsing well and allowing it to dry, as grout darkens when wet, and consider a grout pen or sealant for a fresh, white finish.
Vinegar can indeed ruin grout.
Once lodged in these spaces, vinegar will corrode grout with the passage of time. The grout will eventually wear off. So you should take not to apply vinegar for cleaning purposes if you have unsealed grout in the area.
Below are some of the things you should avoid using when cleaning grout.
The best homemade grout cleaner is often a paste of baking soda and hydrogen peroxide (3%), sometimes with a squirt of dish soap for extra power, creating a fizzing, whitening action that lifts grime when scrubbed with an old toothbrush and rinsed well. For a simpler option, a paste of equal parts baking soda and water works, while a spray of equal parts white vinegar and water tackles mold/mildew but should avoid natural stone.
Baking Soda and Peroxide Mixture
Some professionals swear by a simple mixture of baking soda and peroxide to clean grout.
From cleaning grout between floor tiles to sprucing up the tiles on the wall of your shower, the Magic Eraser Bath with Gain Original Scent is a simple and effective tool.
Hydrogen peroxide – a strong but safe alternative to bleach, is great for cleaning floor tile grout and tackling mould, especially in bathrooms. However, it may lighten coloured grout over time. Steam cleaning is a chemical-free method that effectively removes dirt from grout without scrubbing.
Regrouting is the best option when tiles and grout begin to show signs of discoloration or the stains are so deep that they cannot be removed. As grout ages, it naturally deviates from its original color. If the white grout turns yellow or is covered with stains, you must regrout very soon.
While grout pens are not a permanent solution to some grout issues, they're still an affordable and easy way to help you transform your home. Just be sure that you choose a grout pen in a color that works for your style, the room itself, and the tile.
One of the most frequent grouting mistakes is improper mixing and application. Grout is a precise material, and getting this step right is crucial for its strength and adhesion. Incorrect Water-to-Grout Ratio: Adding too much or too little water can significantly weaken the grout.
4) Be Careful With Coarse Scrubbers
Instead, it would be smarter to use a stone-safe sponge or nylon bristle brush and can scrub out dirt effectively without being abrasive enough to damage the grout or tile around it.
The process is exactly the same: First, mix some baking soda with water to form a paste (a ratio of three parts water to one part baking soda is usually recommended), then apply this to the grout and rinse it away after it has had time to work its magic.
If you're a die-hard DIYer, using Dawn dish soap alone can be a safer option for mild cleaning. Dilute a small amount of Dawn in warm water, scrub the grout with a soft brush, and rinse thoroughly. However, this method is less effective for tackling stubborn stains or deep-seated grime.
To protect your tiles and ensure their longevity, it's essential to understand which chemicals to avoid and adopt safer, more effective cleaning methods.
Grout makes even the most beautiful tiles look old and dirty. The good news is you can make them look brand new with a bit of Coke! Independent house cleaners will pour a small bit of the soda on the area that needs cleaning. They'll let it sit for several minutes before wiping it clean.
