Finally, sparkling clean grout: white grout instead of tedious scrubbing.
The fight against grey, black or yellowed grout
You know the feeling: you scrub, you bleach, you use harsh cleaners – but getting the tile grout white again seems impossible. Especially in bathrooms, grout becomes unsightly over the years. What was once sparkling white is now yellowed or gray. Perhaps you even have black grout due to mold growth or are battling white salt deposits (efflorescence).
Are you looking for ways to lighten or bleach grout ? We have a message for you: Stop cleaning. Start renovating.
Why home remedies often disappoint
Those who Google " home remedies to whiten grout " often end up with baking soda, vinegar, or chlorine. The problem is:
- Only superficial: These products often only remove surface dirt. Discoloration that is deep within the grout's pore system remains.
- Harmful: Acid (vinegar) and chlorine attack the cement over time. The grout becomes rough and attracts new dirt even faster.
- Not permanent: After a few weeks, the grout lines return to being black or yellow.
The solution: Whiten and seal the joints.
The only way to permanently restore white tile grout is with a high-quality grout paint. With Cala Casa, you don't just clean, you seal. Our paint forms a protective shield over the grout. Even black grout turns white – and stays white.

The ultimate expert guide: How to restore white grout, remove efflorescence & renovate
Why do grout lines turn black or yellow?
Before we explain how to make grout white again , we need to understand the cause. Cement grout is naturally porous. It absorbs moisture, grease (in the kitchen), soap scum, and skin flakes like a sponge.
- Yellow grout: Usually caused by grease or cleaning agent residues that discolor due to UV light.
- Black grout: In the bathroom, this is almost always a sign of mold spores that have settled in the damp grout.
- White crusts: So-called efflorescence in tile joints .
Many DIY enthusiasts swear by grandmother's tips. But caution is advised if you want to lighten your tile grout .
Baking powder & baking soda
A paste made from baking soda can loosen surface dirt. But deep-seated stains will remain. Besides, it's tedious work to scrub every inch with a toothbrush.
Vinegar & Lemon
Caution! Cement is alkaline, vinegar is acidic. The acid dissolves the lime in the cement. Regularly using vinegar to whiten grout will eventually damage the grout. The grout will crumble.
Chlorine & grout bleaching
Chemically bleaching grout (e.g., with Danklorix) does offer short-term protection against blackened (mold-like) bathroom grout , but it is harmful to health and the effect is not long-lasting. The mold will return because the grout remains porous.
Conclusion: Home remedies are good for quick cleanups, but unsuitable for a real visual restoration. If you want grout to be white again – permanently – you have to seal it, not just clean it.
Instead of cleaning, experts recommend whitening (also called grout coloring). This involves applying a special acrylic-based paint to the grout. The advantages over cleaning are:
- Total coverage: Whether tile grout was black or stained – after painting it, it is uniformly white.
- Sealing: The paint closes the pores. Dirt can no longer penetrate.
- Time saving: Whitening grout with a brush is faster than scrubbing for hours.
Yes, even black grout will turn white . Cala Casa has such high coverage that even anthracite-colored grout can be completely covered with white.
A technical issue that drives many homeowners to despair is white, salty deposits. People search for information on removing efflorescence from tile grout or bathroom grout .
What are efflorescences?
When moisture penetrates the mortar, it dissolves salts and lime (calcium hydroxide). When the water evaporates from the surface, the salt remains as a white, hard crust. This is often seen as efflorescence in tile joints, on patios , or in damp basements/bathrooms.
How do I get rid of them?
- Cleaning (Acidic): To remove efflorescence from grout , you need an acidic cleaner (cement residue remover), as this dissolves the limescale. Mechanical scraping only provides temporary relief.
- Address the cause: If water is pushing in from "below" (e.g., terrace), sealing is necessary.
- Sealing (Interior): In bathrooms, efflorescence often occurs due to seeping shower water. Cala Casa offers a brilliant solution: Thoroughly remove the efflorescence from the tile grout with our cleaner. Allow the grout to dry completely. Seal it with the grout color. Result: The grout is now waterproof from above. Water can no longer penetrate and wash out salts. This prevents new efflorescence from forming in your tile grout .
If the grout is black , it's often mold. Simply painting over it won't do the trick. The correct way to deal with it is:
- Kill the mold with a mold killer.
- Clean the joint thoroughly, removing all grease.
- Use Cala Casa to whiten grout . Our paint contains fungicidal properties, and the smooth surface prevents new spores from adhering. This restores the grout to its original white color, promoting a healthy bathroom environment.
Whether you need to remove efflorescence from grout , want to lighten tile grout , or are wondering how to get grout white again without replacing the tiles:
Say goodbye to ineffective home remedies. The answer is systematic grout whitening .
- Cleaning (removing grease/limescale/efflorescence).
- Painting (sealing & coloring).
- Wipe clean (finish).
Make your grout easy to clean. Whitening your grout once with Cala Casa will save you hours of cleaning in the future.
