Cleaning experts shared how to whiten black-stained grout in under five minutes using an all-natural method.
Cleaning grout proves surprisingly rewarding once you begin, and it’s an excellent method to refresh your bathroom without any expenditure. Whether the grouting surrounding your shower has acquired an unfortunate orange tinge from shampoo residue, or your floor tiles have turned grey or black due to accumulated dirt or mould, the cleaning specialists behind the Instagram account @thecleangroup have the solution.
Tiles themselves are straightforward to maintain, but grout presents greater challenges because of its porous nature and vulnerability to discolouration. Combined with bathroom humidity, it creates perfect conditions for mould to flourish, and you’ll find it speckles the grouting.
The cleaning professionals maintained that achieving whitened grout with “instant results” requires neither foams, gels, pastes, electric scrubbers, nor brushes.
They maintain that the secret to pristine grout involves using a particular cleaning powder alongside one natural product – a magic eraser sponge.
Within the post’s comments section, the professional cleaners stated: “You cannot beat a magic eraser.”
Magic erasers consist of melamine foam, which essentially functions like extremely fine sandpaper. This property enables them to tackle those incredibly stubborn marks on various surfaces, particularly grouting. The cleaning specialists noted that their grout technique “blew a client’s mind” upon witnessing the transformation.
The method
For this method, purchase a packet of basic, unbranded magic erasers and dip them directly into some Bar Keepers Friend powder.
Bar Keepers Friend powder is a versatile surface cleaner that removes stubborn marks in kitchens, bathrooms and beyond using its non-bleach, plant-derived formula.
Then, gently scrub your grout lines and “watch the real colour come back”. The specialists confirmed they cleaned all the grout in their bathroom “in less than five minutes”, and noted that it’s effective on textured tiles as well.
If you’d prefer to avoid even light scrubbing, they emphasised that a gentle wipe works equally effectively and “it works just as well”.
