Got a stubborn stain on your marble countertop? Marble is durable yet delicate, easily damaged by harsh cleaners. Luckily, there's a gentle, time-tested solution using Blanc de Meudon (whiting powder), a natural calcium carbonate powder favored by professional cleaners for its non-abrasive properties.
To effectively clean stains without harming the stone, follow this simple paste method we've used successfully on countless marble surfaces.
Contents 1. Put two cups of Blanc de Meudon in a container.
2. Pour a cup of water.
3. Mix to obtain a dough not too hard (the quantities depend on the quantity you need).
4. Spread this paste on the marble.
5. Leave to stand for 5 minutes.
6. Rinse by rubbing with just a little clear water.
There you go, your marble surface is clean :-)
This trick works regardless of the type of stain. Cleaning stained marble becomes effortless, thanks to this reliable method!
Little known but incredibly versatile, Blanc de Meudon is a staple for home cleaning and even decoration.
If the stain persists, add a little salt to the mixture and repeat the same process, letting it act a little longer if necessary.
Stains from wine, rust, acid, champagne... nothing stands a chance!
You can also use Meudon white to de-yellow marble and maintain black marble.
From old living room fireplaces to antique Louis XV furniture or bathroom floors, marble is everywhere.
For oil or grease stains, if the paste doesn't fully remove it, try gently scraping with a piece of onion first, then reapply the method.
It may sound unusual, but this trick effectively loosens grease on marble.
