We bought a house with a marble shower that has rust stains from well water.

What is the best way to clean them and can they be cleaned?? Marilyn

Marble rust stain removal can be tricky. These are most likely rust stains, but I don't think it's from the well water.

If the stains were from the water, then the shower would show staining throughout and it does not.

What has probably occurred here has to do with the nature of many white marbles. White marble, particularly Carrara often contains iron deposits.

If/when the marble is saturated with water, these iron deposits hidden inside the stone will oxidize. Then, as the water moves through the stone to the surface, it carries the rust with it resulting in yellow-brown-orange stains on the marble.

This is not uncommon and seen mostly in floors after a flood or in areas the are constantly exposed to water like a shower.

Looking at the picture you see a heavy stain on the small strip next to the shower door runner.

If this stain was caused from the water, then the rust stain would extend down the entire side like a drip. But instead it stops at the seam, which is another indication this stain is due to internal oxidation of iron deposits and not from well water.

If the grout seams are intact, this typically will occur. A little water may absorb into the marble during a shower, but it will quickly evaporate and unless an iron deposit is directly below the surface you won't see any rusty discoloration.

However, when there are voids or cracks in the grout or caulk, then water can get beneath the tile where it will not evaporate quickly and can absorb into the stone. It travels through the stone to the surface oxidizing the iron along the way.

So, first thing to do is inspect all grout seams and fix any voids or cracks. Then you can work on the rust stain removal.

Marble stains are not removed by common methods since the stain is below the surface. Also, the method required depends on what stained the marble.

However, you'll find detailed steps for cleaning marble stains of all sorts in the Removing Granite & Marble Stains e-book (see links above and below).

Or simply use the Rust Stain Remover Product linked in the first question above.

Unfortunately, rust stains tend to be stubborn. They be removed, but you'll likely have to repeat the process several times.
