Cleaning Brown Stains On Marble Floor
by Sue
QUESTION:I have a carerra marble bathroom floor. There are dull yellow stains in the high traffic areas. How do I clean it?ANSWER:Cleaning marble stains is fairly easy in most cases, but it can't be done using conventional cleaning methods since stains occur when a substance is absorbed into the marble below the surface.Also, white marble like Carrara will often contain iron deposits. If the marble tile is exposed to a constant source of water, or if the floor was flooded and water is trapped beneath the tiles it can saturate the marble exposing the iron deposits to water. When this happens the iron oxidizes and the rusty water is carried to the surface to evaporate leaving brown/yellow/orange stains. So, if any of the above is a possible cause, then you need to eliminate the source of water if a leak, or make necessary repairs to grout, etc. if water may be getting under the tiles this way. If a one-time event like a flood, then it's possible that all the water is now dried out and the marble stains were caused all at once. The one confusing issue is that the stains occur in the traffic path. It's hard to know if this is coincidence or part of the cause. Another consideration is that some bath mats can contain dyes that will cause marble stains, especially when made of natural materials. The proper method for cleaning marble stains depends on what stained the marble, so it's helpful (but not absolutely necessary) to know. You'll find complete step-by-step instructions on how to remove all types of marble stains in the Removing Granite & Marble Stains e-book. It also details what to do when you are not sure what actually caused the stain. Good Luck, Ryan P.S.
