Efflorescence on tile and grout is a curse on the decorative look of your showers. But not only does it ruin the aesthetic beauty, if not removed, it can clog your drains and crack your tile. Many people try to remove efflorescence with sharp tools, leading to scratches on the surface. Here we will discuss how to remove efflorescence in the proper way.


But before we explain the right way of efflorescence removal, we will first know in-depth about this build-up.

What is Efflorescence?

Efflorescence is a residue of mineral and calcium deposits that settle on the surface once the water evaporates. This water originates from leftover moisture or water underneath the tile at the time of installation. The water mixes with the minerals in the concrete mud bed, grows in volume and travels to the outside through a drain or any other seepage. If not removed at the right time, it can crack your tile and grout and also clog your shower drains.

How is Efflorescence Formed?

Efflorescence mainly forms when there are calcium and mineral deposits present in the concrete mix used for installing the tile. Moreover, if water is penetrating underneath the tile, it mixes with the minerals present there and forms a solution called efflorescence. This solution travels to the top of the surface where the water evaporates. The deposits then settle on the tile and grout surface. Thus, efflorescence only forms on surfaces that have been constructed or installed using porous materials. These porous surfaces allow the penetration of water to and fro.

Many people mistake efflorescence to be mold. But this whitish cement like residue does not spread like mold or have any health hazards. It only ruins your shower flooring. Let us now understand how to remove efflorescence the right way.

Dangers of Efflorescence:

  • Efflorescence on the shower tile and grout is a clear indication that there is accumulation of water underneath the floor or wall tile. If not rectified, this moisture may lead to mold development, weakening of the structure, termite infestation and many such problems later on.
  • A lot of efflorescence can clog your drains and crack your tile as well. This will lead to expensive tile and grout repair costs later on.
  • It does not cause any health hazards.

What are the Different Ways to Remove Efflorescence?

It is not tough to remove efflorescence from tile and grout. You can either use chemical cleaners or a sand blasting technique. But, sand blasting might cause severe damage to the tile surface. It is better to use a chemical cleaner to remove shower efflorescence.
